OPP-SENS®

Air flow temperature transmitter
Type Item no. ADG Euro / pc.

OPP-SENS® Air flow temperature transmitter FT… See See
for measuring of air flow in ducts, with adjustable following following
mounting for adjusting the depth of immersion. page page
The microprocessor technology guarantees a constant
linear output, even at low air speeds.
Illuminated display & control unit with
autoadapt and capacitive buttons. The duration of
lighting, contrast, display (temperature, flow or alternating) and
temperature unit can be set via the menu.
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 – 2 m / s 0 – 2,5 m / s 0 – 4 m / s 0 – 5 m / s
0 – 6 m / s 0 – 8 m / s 0 – 10 m / s* 0 – 12 m / s
