The HygroFlex5-EX series of humidity & temperature transmitters is designed for fixed installation in applications
where high measurement accuracy is required. The transmitters can be used with all ROTRONIC ATEX probes in
the AirChip3000 series. Standard probes may not be used.
The HygroFlex5-EX has two analog current outputs for relative humidity, temperature or a derived parameter, e.g.
dew point, enthalpy, mixing ratio, etc. The HygroFlex5-EX transmitter has an internal digital service interface.
Digital communication with a PC allows simultaneous monitoring of three parameters: relative humidity,
temperature and calculated value. The HygroFlex5-EX can measure within the ranges of 0 to 100 %RH
and 100 to 200°C (-148 to 392°F). The working temperature range of the electronics is limited to -40 ... 60°C
(-10 ... 60°C with optional LCD).
The probes are equipped with proven, durable sensors.
•User-configurable adjustments
•Calculation of humidity parameters such as dew point or frost point
•Interchangeable probes for humidity and temperature calibration and adjustment outside Ex zones
•Simulator mode
•Simple updating of the firmware for both the HygroFlex5-EX transmitter as well as the Hygroclip-2 probe keeps the devices in the HygroFlex5-EX series up to date with improved functionality.
Note:
•The housings for all types with display are designed for horizontal mounting
Mechanical configurations and dimensions
Display and keypad option
The optional LCD does not have a backlight.
The first line of the display shows the relative humidity and the second line the temperature (or a calculated value,
e.g. dew point, frost point, ...).
The display can be configured to show a trend indicator at the start of every line:
▲: Increasing value
▼: Decreasing value
In the event of an alarm the display shows the symbol [ ! ] to the right of the value
