Air Differential Pressure Transmitters PDM-series is an extremely versatile 
transmitter for monitoring pressure and air velocity.
The Air Differential Pressure Transmitters PDM-series have 
Field selectable English or Metric ranges.
3 pressure ranges in same unit.
Available pressure ranges:
0-25 Pa, 0-50 Pa or 0-100 Pa.
0-250 Pa, 0-500 Pa or 0-1250 Pa.
+25 to -25, +50 to -50 or +100 to -100 Pa.
With or without LCD display for Air Differential Pressure Transmitters PDM-series.
Adjustable damping of output signal 
(with LCD display only).
Ability to select a square root output for use with pitot tubes and other similar flow sensors.
Along with these features, the patented magnetic sensing technology provides exceptional long term performance and enables the Air Differential Pressure Transmitter PDM-series to be the single solution for your pressure and flow applications.
The accuracy for Air Differential Pressure Transmitters PDM-series is:
±1% for 50 Pa, 100 Pa, 500 Pa, 1250 Pa, 
±2% for 25 Pa, 250 Pa and all bidirectional ranges.
The output for Air Differential Pressure Transmitters PDM-series is 0-10 Vdc,
on request 4-20 mA and 0-5 Vdc output.
