Aerosense Series DPT-R8-3W Differential Pressure Transmitter

Listing ID #3501885

Aerosense series dpt-r8-3w differential pressure transmitter
series dpt-r8-3w differential pressure transmitter monitors pressure
the series dpt-r8-3w differential pressure transmitter is an extremely versatile transmitter for monitoring pressure. The compact package is loaded with features such as 8 selectable ranges, 2 selectable outputs, optional display and optional auto-zero feature which electronically adjusts the transmitter zero at predetermined time intervals (every 10 minutes). The auto-zero adjustment takes 4 seconds.
The az calibration eliminates all output signal drift due to thermal, electronic or mechanical effects. Optional display and auto-zero feature available.
Product applications:
building pressure monitoring
duct pressure monitoring
filter condition monitoring
note! supply voltage must be connected one hour before the 0-point adjustment is carried out.
Loose both tubes from the pressure inlets + and -
push zero button until the red led turns on.
Wait until led turns off and then install tubes again to the pressure inlets.
It is recommended to adjust the zero point every 12 months during normal operation.
If the transmitter is equipped with automatic zero element the manual push button adjustment is not required.
Az-calibration is a function in the form of an automatic zeroing circuit built into the pcb. The az-calibration electronically adjusts the transmitter zero at predetermined time intervals (every 10 minutes). The az-calibration eliminates all output signal drift due to thermal, electronic or mechanical effects, as well as the need for technicians to remove high and low pressure tubes when performing initial or periodic transmitter zero point calibration.
