For precise flow measurements it is required often to record temperature and humidity of the flowing medium. For this purpose we offer the models of the series HUMTMP, which combine a sensor for the determination of temperature and humidity in one device.
The sensor can be used for pressures up to 16 bar and it is equipped with a screw-in thread G1/2" for installation. The Pt100 resistive element and the capacitive humidity sensor are open in direction of the medium. A glass leadthrough separates electronics and sensors. The sensors are protected from high flow rate and particles by a plastic or stainless steel sinter filter cap.
Product features include:
- Combined measurement of temperature and humidity
- Measuring range temperature: –10 up to +60°C
- Measuring range humidity: 0 up to 100% relative humidity
- Mechanical connection: G1/2"a
- Quick response time
Temperature is measured by a passive Pt100 element and humidity is measured by a capacitive measuring element. The sensors are protected from high flow rates and particles by a plastic or stainless steel sinter filter cap.
The connection thread with O-ring and integrated glass leadthrough allows pressure-tight connecting of the sensor in closed compressed air tube systems with up to 16 bar overpressure.
The flow rate at the measuring head must not exceed 40 m/s. Furthermore, humidity sensors are subject to ageing as a matter of principle and must be recalibrated from time to time or replaced.
