OPP-SENS® Duct enthalpy

humidity temperature sensors
Type Item no. ADG Euro / pc.

OPP-SENS®Duct humidity temperature sensor (enthalpy) HTx-xxx-I-... see see our
For measuring enthalpy temperature in air ducts. following current
The optional display enables you to configure the transmitter such page price list
that it indicates and outputs absolute or relative humidity or the
mixture ratio instead of enthalpy. The absolute air pressure can also
be set via the display.
Display and control unit with autoadapt and capacitive
button (option). This enables the NFC function, allowing easy
sensor parameterization via a smartphone.
5-point calibration: linear interpolation of the output
curve over 5 user-defined points.
10 offset points: linear shift of characteristic curve the output
signal via 10-level rotary switch.
Captive lid with 8-way positioning.

10 measurement ranges can be set using the rotary switch:
0 – 50 kJ / kg 0 – 80 kJ / kg 0 – 100 kJ / kg* 0 – 200 kJ / kg
0 – 400 kJ / kg 0 – 1000 kJ / kg -50 – 50 kJ / kg -50 – 200 kJ / kg
