Modbus High Temperature Humidity Sensor ANDARFT/R-MD/HT is for measuring the relative humidity/temperature in outdoor areas or indoor areas subject to high requirements. The measuring transducer measures the temperature and humidity via an internal sensor and converts the value into a standardized analog output signal in the range between 0-10V/4-20 mA. Additionally, a passive temperature sensor can be connected. Various measuring ranges are available depending on the model. The sensor features long-term stability and no recalibration is required.
Additional options for sensor ANDARFT/R-MD/HT (surcharges):
- relay.
Alternative sensor versions:
- High Temperature Humidity Sensor ANDARFT/R-X/HT.
