The MFT 2.1 dew point transmitter, based on a capacitive polymer sensor, is designed in probe form, with the sensor element in direct contact with the sample gas, for good response behaviour.
- Cost-effective detection of the dew point
- Fast response time
- Low temperature dependence
- Low cross-sensitivity
A fine-pored, moisture-permeable stainless steel sintered cap is available as an option which effectively protects the sensor from contamination and mechanical effects, if required. A high-pressure version up to 150 bar operating pressure with ½″ screw-in thread is also available for monitoring tasks in compressed air systems.
Analogue and digital interfaces are available for measured value output, with the option of a customer-specific adaptation of the measured variable (dew point, relative humidity, ambient temperature) with analogue output as a 4-20 mA current loop or 0-5 V voltage output. A combination of several, simultaneously output measured variables with a digital interface is also possible.
- Integrated plausibility check
- Ensuring trouble-free operation through a self-diagnosis system
