OPP-SENS®

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

OPP-SENS® Volume flow temperature transmitter VT… See See
for measuring of volume air flow in ducts, with adjustable following following
mounting for adjusting the depth of immersion. page page
Via the optional display, the transmitter can be configured to show
either flow volume in m³/h or flow velocity in m/s. The size of the
duct and a correction factor can also be set via the display. 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.

Volume flow measurement range:
0 – 9,999 m³ / h, use correction factors for parametrization

10 measurement ranges can be set using the rotary switch:
