HVAC40… SERIES- RH & Temperature Transmitters / Hygrostats
Humidity, Temperature
Transmitters and hygrostats series for measuring temperature, relative humidity and dew point in HVAC applications.
Over 40 years of experience in worldwide applications combined with a new design on accuracy, stability, simplicity and connectivity: this is the HVAC40 series. These transmitters and hygrostats measure temperature, relative humidity and dew point using an interchangeable relative humidity and temperature digital sensor.
The probe is available in three different versions:
- fixed vertical probe for wall mounting
- fixed probe with 2m cable
- fixed duct horizontal probe
Available outputs, depending on the model:
- RS485 Modbus-RTU digital output
- 0…10 V voltage analogue output
- 0…20 mA / 4…20 mA active current analogue output
- 2-wire (current loop) 4…20 mA analogue output
- ON/OFF relay switch
Relay versions with settable alarm thresholds, hysteresis and delay and supplied as standard with LCD display. Optional LCD for all other versions.
The instruments are factory calibrated and ready for use.
