Humidity and temperature transmitter HTT-21_22
Product description
Transmitter that converts temperature and relative humidity of gas (e.g., compressed air) in tanks and pipelines into a current signal.
Features of the transmitter:
-
- dual output signal: 2×0÷20mA,
- integrated temperature sensor,
- programmable conversion range of measured quantities,
- programmable humidity unit: %RH or °Cdp,
- programmable range of output signal
- hermetic housing (IP65)
- The transmitter is configurable with a computer via the IF-2013U interface.
Instead of a signal proportional to relative humidity, an output proportional to the dew point temperature can be selected. The processing range of the measured quantities can also be changed.
