HD2011TC2-1  External probe L=330 mm with a cable L=5 meters.

Relative humidity and temperature transmitters convert the variation that occurs simultaneously inside a
relative humidity capacitive sensor and a resistive Platinum sensor both into a 4 -20mA linearized signal and,
depending on the various models, into 0 - 1V, 0 - 10V, 0 - 20mA or 4 - 20mA signals.
They are distinguished in two-wired current-looped passive transmitters, separately power-supplied active
transmitters (with voltage usually of 24Vac), and finally passive and active transmitters which can work with
either of the two possible kinds of power supply - two wires with current loop, or grid of 24Vac.
