Rotronic Hygro Flex 3 Transmitters For Humidity and Temperature
The new HygroFlex3-series is the latest development in HVAC transmitters for relative humidity, temperature and dew point. Based on AirChip3000 technology, the instruments achieve a degree of accuracy not seen before.
In combination with advances in sensor technology and integration, the HygroFlex3-series provides superb precision and state-of-the-art functionality, taking humidity, temperature and dew point measurements to a whole new level of performance and reliability (< 2 % rh / 0.3 K).
High flexibility
• Two freely selectable and scalable analog outputs
• Analog outputs assignable to relative humidity, temperature or dew point
• 2-wire or 3/4-wire systems available
• Two integrated relay contacts available as options to convert the transmitters to thermostats/hygrostats
AirChip3000
• Compensates humidity and temperature over 30,000 reference points
• 2,000 data point memory
• Dew/frost point calculation
• Sensor auto-diagnostics and automatic correction
• Active alarming and information
• ASIC (Application Specific Integrated Circuit), micro-controller and EEPROM on one chip
Fast response and precision measurement
• By decoupling the Pt100 temperature sensor from the probe, thermal response is significantly improved
• Use of Pt100 1/3 Class B sensors for maximum accuracy
• Relative humidity, temperature and dew point measurement
• Outstanding accuracy and repeatability
• Hygromer® IN-1 humidity sensor
• Auto-diagnostics and automatic correction
• Freely selectable and scalable analog outputs
• Also available as hygrostat and thermostat
