Rotronic Hygro Flex 4 Transmitters For Humidity and Temperature
The new HygroFlex 4-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 HygroFlex HF42-, HF43- and HF45- transmitters 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 (< 1 %rh / 0.2 K).
Practical display
• Display of the measured values on a clear, backlit graphic display with trend indicators
• Configuration by keypad possible
Tried-and-tested housing
• Robust industrial housing
• Wall or duct mount versions
Outputs
• Two freely selectable and scalable analog outputs
• 2-wire and 3/4-wire systems available
• Optional digital outputs allow integration on a network via RS485, Ethernet and even wireless connection
Fast response and precision measurement
• Integrated probe
• By decoupling the Pt100 temperature sensor from the probe, thermal response is significantly improved
• Heat from the electronic components is not transmitted to the sensors, thereby improving the accuracy of the system
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
• 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
• Network compatibility with digital outputs
