SCHMIDT® Flow-sensor SS 20.260 for process technology
For the employment in process technology the latest SCHMIDT® flow sensor SS 20.260 offers three crucial upgrades compared to his forerunner. With an expanded measuring range of 0 … 50 m/s the sensor can be applied for flow rate control in a wide range of systems. Many processes require the measurement of heated gases and therefore an enhanced operating temperature. Depending on the configuration of the SS 20.260 it is up to 120 °C. The temperature can be measured with an additional linear output and no separate sensor is required any more. The unit is ro-bust due to a chamber in which the sensing element is protected against impacts. The stainless steel sensor tube is available in different length and thus can be placed at the correct position regardless of the size of the duct. Two LED’s indicate the correct operation or inform about wrong supply voltage or sensor defects.
Applications: Flow measuring in air ducts, volume flow measur-ing in test benches, control of combustion air of oil, wood, gas or coal burners, flow control in cool-ing or drying constructions.
Technical data: Immersion sensor with integrated transducer.
Use of sensor: Free air and guided air in ducts from 25 to 1.000 mm (1 to 40 inch).
Medium: Air, Nitro-gen, Argon and other non-burnable gases. Measuring ranges: 0 … 2.5/10/20/40/50 m/s.
Pressure: Atmospheric.
Power supply: 24 VDC / power consumption only 30 mA.
Output: 0 … 10 V / (0)4 … 20 mA linear.
Functional display: 2 Status LED’s

Massflow under control
Massflow gas measurement is independant of temperature and pressure, thus controlling a process gas can be stable and reproduceable. Massflow controllers contain a PID-controller and can be driven through norm signal or field bus. Massflow meters are without actuators and are only for measuring massflow.

The FMA1000 Series industrial air velocity and temperature transmitter/indicator measures and displays air velocity as well as air temperature in research and development labs, HVAC applications, and other manufacturing processes. The sensor design is based on three RTD elements, one measures air temperature and the other two measure air velocity by measuring the heat loss from the RTD sensor as it cools down by the air flow.
The FMA1000 series offers many standard features such as display of air velocity and temperature, two analogue outputs corresponding to air velocity and temperature, high and low voltage alarm outputs, USB serial interface, and Windows® based data logging software. The FMA1000 displays the air velocity in different engineering units such as FPM, m/sec, miles/hour, and km/hour. The air temperature is displayed in °C or °F.
