HygroFlex5 Series Humidity Transmitters
Features the possibility to output all psychrometric calculations as an analog signal
This transmitter requires a HygroClip2 probe which is sold separately.
The Rotronic HygroFlex5-series is the latest development in transmitters for humidity, temperature and dew point. The innovative HygroFlex5-series features the possibility to output all psychrometric calculations as an analog signal.
The HygroFlex5-series is compatible with HygroClip2 probes with integrated AirChip3000 technology - which achieve a degree of accuracy not seen before. Advances in sensor technology and integration allow the Rotronic HygroFlex HF52-, HF53- and HF55- transmitters to provide superb precision and state-of-the-art functionality, taking humidity, temperature and dew point measurements to a whole new level of performance and reliability. AirChip3000 technology compensates humidity and temperature over 30,000 reference points, has a 2000 data point memory, calculates dew/frost point, has sensor auto-diagnostics and automatic correction.
The HygroFlex5-series has an optional backlit graphic display of measured values with trend indicators. Wall or duct mount versions with robust industrial housing are available. The Rotronic Hygroflex5-series transmitters have two freely selectable and scalable analog outputs. Units are available as 2-wire (HF52), 3/4-wire (HF53) and digital (HF55) transmitters. The optional digital outputs allow integration on a network via RS485, Ethernet and wireless connections.
