Laminar flow monitoring – reliable and robust – even with intensive cleaning processes and the use of aggressive media in pharmaceutical plants

Laminar flow monitoring - reliable and robust - even with intensive cleaning processes and use of aggressive media in pharmaceutical plants Introducing the SCHMIDT® Flow Sensor SS 20.715 LED, a robust solution for continuous monitoring of laminar airflow in clean rooms and clean applications. With sensor elements completely encapsulated in stainless steel, it impresses with its resistance to aggressive media and dirt and also offers very good protection during the rough cleaning of pharmaceutical systems. Monitoring the flow in cleanrooms and clean areas A direction-defined air flow in clean rooms protects products from contamination and disruptive particles are safely removed. For this purpose, a uniform air flow from the ceiling to the floor is maintained in clean rooms with high cleanliness classes ("directed, low-turbulence displacement flow"; monitoring range from wN = 0.36 to 0.54 m/s). The measurement is carried out on the clean room side after the terminal filters. Since the air circulation is throttled during idle times, high-precision measurement of the air speed from 0.1 m/s is necessary. The solution: measuring the supply air flow with the SCHMIDT® flow sensor SS 20.715 LED According to the EN ISO 14644-3 standard, the air speed is measured at a distance of around 150 to 300 mm below the front surface of the filter. For easy installation in ceiling and wall systems, the thermal SCHMIDT® flow sensor SS 20.715 LED offers a cleanroom-compatible quick mounting system. The sensor is extremely compact, as all the electronics are built into the sensor tube and therefore no turbulence is generated in the low-turbulence displacement flow. Individually adapted to each application There are 3 standard variants to choose from for optimal installation in different applications. The laminar flow sensor can be mounted on the wall in a straight version with a sensor length of 300 mm or in an angled form under the ceiling of the clean room or the bottling plant. The angled design can be configured with the dimensions 270 x 300 mm or 150 x 300 mm (where the first dimension defines the distance to the ceiling; plus mounting system). Robust solution for pure applications with aggressive media or intensive cleaning The thermal SCHMIDT® flow sensor SS 20.715 LED is the robust solution for extremely challenging clean room applications. Product changes in pharmaceutical filling plants or simply internal requirements force operators of clean rooms and plants in clean areas to clean them regularly. If aggressive media are used or if more intensive cleaning is required due to significant or very stubborn dirt, the new laminar flow flow sensor SS 20.715 LED with double pin sensor head made of stainless steel is the first choice. The double pin sensor was designed precisely for the aforementioned needs and is ideally suited for demanding applications thanks to the sensor elements completely encapsulated in stainless steel. In addition to the flow rate, the SS 20.715 LED also records the medium temperature from -20 °C to +70 °C. Thanks to the SCHMIDT® quick mounting system, which is suitable for clean rooms, the SS 20.715 LED can be exchanged for an existing sensor without any additional effort and installed as easily as usual. The sensor works without moving parts and due to the measuring principle, drift or aging are irrelevant. Due to the sensor elements being completely encapsulated in stainless steel, the maintenance of the sensor is reduced to an absolute minimum. However, should cleaning be necessary, this can be carried out very easily and in a variety of ways. High accuracy and detection of the smallest currents The special double-pin sensor head records flow velocities from 0.1 m/s up to 10 m/s in three selectable measuring ranges (1 / 2.5 / 10 m/s). In order to obtain precise measurement results in this speed range, each sensor is individually adjusted and calibrated in a high-quality wind tunnel. On request, the sensor can also be supplied with a DAkkS-accredited calibration. Highlights of the SCHMIDT® flow sensor SS 20.715 LED: For laminar flow applications with aggressive components or intensive cleaning processes Sensor elements completely encapsulated in stainless steel enable extremely easy cleaning Very robust and extremely compact design (electronics integrated in the sensor tube) 3 sensor length variants: straight design: 300 mm angled design: 150 or 270 x 300 mm Measuring ranges 0 … 1 / 2.5 / 10 m/s Temperature measurement range from -20 to +70 °C Linear analog output for measured value output Integrated sensor self-monitoring with error signaling Operating status display and serial number of the sensor visible on the sensor when installed Special version for laminar flow monitoring in clean rooms with quick assembly technology for easy installation in clean room ceiling and clean room wall systems DAkkS-accredited calibration (optional) SCHMIDT® Flow sensor SS 20.715 LED: Especially designed for laminar flow applications with intensive cleaning processes: Thanks to the sensor elements completely encapsulated in stainless steel, they are ideal for demanding applications in clean rooms and in clean processes suitable and resistant to aggressive media.

Flow Sensor SS 20.700 for heavy-duty applications in air and other gases

Flow measurement in harsh conditions The SCHMIDT® flow sensor SS 20.700 is a robust solution for highly demanding heavy-duty applications in air and other gases. With sensor elements completely encapsulated in stainless steel, it impresses with its resistance to aggressive media and dirt.   Flow rates of gases – an important parameter in industrial processes Energy saving and quality assurance measures are becoming increasingly important in the production process of industrial processes. The precise measurement of volume flows and flow rates of the gases plays a major role. The requirements for the intended flow sensor are high: The sensor should deliver precise measurement results in different gases, high overpressures and wide temperature ranges - even under the most difficult environmental conditions. Another criterion when choosing the right sensor is the avoidance of maintenance and high follow-up costs. Users want easy installation and reliable readings over the years. Robust solution for heavy-duty industrial processes and compressed air technology The thermal SCHMIDT® flow sensor SS 20.700 is the robust solution for extremely challenging industrial applications. It can be used for various applications such as compressed air monitoring, gas monitoring for process burners, metering of gas consumption and much more. The double pin sensor was designed precisely to meet the needs of so-called "heavy-duty applications" and is ideally suited for demanding applications such as e.g. B. the production of bio-gas. In addition, the sensor is resistant to aggressive media. In addition to the flow velocity, the SS 20.700 also records the medium temperature up to +120 °C. It can be used in small pipes from DN 40 and can also record the volume flow in large ducts up to a sensor length of 600 mm. The sensor can be used up to an overpressure of 16 bar. The installation of the sensor is very easy: Screw in the sensor using the supplied through-bolt, align it in the gas flow and in the middle of the pipe, connect electrically - done. The sensor works without moving parts and due to the measuring principle, drift or aging are irrelevant. Due to the sensor elements being completely encapsulated in stainless steel, the maintenance of the sensor is reduced to an absolute minimum. However, should cleaning be necessary, this can be carried out very easily and in a variety of ways - in the spirit of "heavy-duty".   High gas velocities and special gases The special double pin sensor head records flow velocities from 0.1 m/s up to 220 m/s. In order to obtain precise measurement results in this very wide speed range, each sensor is individually adjusted in a high-quality pressure wind tunnel. The sensor can be supplied in individual versions for use in different gases, e.g. B. for pure oxygen, nitrogen, argon, CO2 and other gases.   Individually adapted to each application There are 2 standard sensor lengths to choose from for optimum installation in different pipe diameters. The SS 20.700 can also be ordered in a remote version for difficult installation conditions. The standard sensor lengths are available here, the cable length between sensor and housing can be freely defined (up to 10 m). In addition to various standard measuring ranges, the flow sensor can also be supplied with an application-specific measuring range. For media with an oxygen content of > 21% by volume, all parts that come into contact with the medium must be cleaned of grease, oil or other combustible components. Two special variants "Oxygen O2 > 21%" and "Fat-free and oxygen O2 > 21% (LABS-free)" provide the necessary security for these applications.   Modular function extension In addition, the SS 20.700 has a module interface as standard for the modular expansion of the sensor's range of functions. The sensor can be parameterized via the module interface, a Bluetooth® wireless transmission to the SCHMIDT® Sensor App can be implemented or the additional 7-segment display MD 10.020 can be connected. The SCHMIDT® data logger DL 10.010 can also be operated via the module interface. The module interface also has an LED light ring, which signals communication with other additional modules by means of different colors and pulsing. The sensor parameterization enables e.g. B. a scaling of the measuring range to individual needs, the settingment of a damping and much more.   Highlights of the SCHMIDT® flow sensor SS 20.700: Sensor elements completely encapsulated in stainless steel Large flow measurement range from 0.1 to 220 m/s Temperature measurement range from -20 to +120 °C For air and gases in applications with harsh conditions (medium with aggressive components, pollution, high humidity) Very robust design and overpressure resistant up to 16 bar Easy cleaning thanks to the encapsulated stainless steel surface Sensor configuration via module interface   SCHMIDT® flow sensor SS 20.700: Especially designed for "heavy-duty applications": Thanks to the sensor elements completely encapsulated in stainless steel, they are ideal for demanding applications such as e.g. B. the production of bio-gas etc. Suitable and resistant to aggressive media.

Duplex flow sensor SS 20.415 redundant laminar flow monitoring

Redundant laminar flow monitoring at one measuring point SCHMIDT® duplex flow sensor SS 20.415 Twin* is a high-precision 2-in-1 flow sensor solution for laminar flow monitoring. A redundant monitoring of the laminar flow with two independently working flow sensors at one measuring point, without mutual interference, is thus successfully solved.   Monitoring the flow in cleanrooms and clean areas A direction-defined air flow in clean rooms protects products from contamination and disruptive particles are safely removed. For this purpose, a uniform air flow from the ceiling to the floor is maintained in clean rooms with high cleanliness classes ("directed, low-turbulence displacement flow"; monitoring range from wN = 0.36 to 0.54 m/s). The measurement is carried out on the clean room side after the terminal filters. Since the air circulation is throttled during idle times, high-precision measurement of the air speed from 0.1 m/s is necessary.   Measuring and controlling the supply air flow with the SCHMIDT® duplex flow sensor SS 20.415 Twin Two redundantly working flow sensors such as the SS 20.415 LED are often installed in one application, for example to map the control and monitoring of the laminar flow independently of one another. Limits are often reached when it comes to the optimal placement of the two sensors due to cramped spatial conditions. Even if the assembly can ultimately be implemented, the mutual influence of the two sensors is a big unknown. With the SCHMIDT® duplex flow sensor SS 20.415 Twin*, both of the above problems can be easily solved. By combining two flow sensors that work completely independently, it has been possible to implement a redundant flow measurement at the same measuring position and to eliminate the mutual influence of the two probes. Both flow signals are made available separately from each other via two analog outputs. Thanks to the SCHMIDT® quick mounting system, which is suitable for clean rooms, the duplex sensor can be exchanged for an existing sensor without any additional effort. The installation effort is identical, the space required for installation is slightly higher.   Highlights of the SCHMIDT® Duplex flow sensor SS 20.415 Twin*: Redundant protection of laminar flow applications Two fully-fledged flow sensors working independently of each other in one unit Easy installation at a measuring point No mutual interference of the measurement Constrained space becomes a minor matter Plug and play and quick assembly Precise measurement of small flow velocities [wN] Straight and angled design for wall or ceiling mounting SCHMIDT® duplex flow sensor SS 20.415 Twin*: Optimally suited when double protection of the laminar flow monitoring is required and when space is limited. Two redundant flow signals from one measuring point - without mutual interference. Available in straight and angled designs (depending on mounting requirements * protected by DE 20 2021 103 497.1
