HVAC40 – HVAC Transmitters and Hygrostats

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 2 m cable
fixed duct horizontal probe
Available outputs, depending on the model:

RS485 Modbus–RTU digital output
0…10 V voltage analog output
0…20 mA / 4…20 mA active current analog output
2-wire (current loop) 4…20 mA analog 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.
