OPP-SENS® Differential air pressure

volume flow transmitter
Type Item no. ADG Euro / pc.

OPP-SENS® Differential air pressure PV… See see our
volume flow transmitter following current
for measuring pressure differential and volume flow of page price list
non-combustible and non-aggressive gases and air.
With manual zero point setting.
Selectively configurable from 0 – 1,000 Pa and 0 – 4,000 Pa,
depending on desired accuracy.
Adjustable linear or square root extraction output of pressure
differential on analog transmitters (factory setting: linear). SENSORS
The data is always transmitted in the form of registers in the
bus version.
Volume flow is calculated by entering correction factor k or
selecting a fan manufacturer and is output as a linear output
signal or via bus.
Volume flow measurement range: 0 – 99,000 m³ / h.
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.
Optional integration of fan walls/fan grids.
10 pressure sensor ranges selectable with rotating switch:
