Models with "D" in part number can read Gage or Differential pressure.
To read Gage pressure, connect center port to pressure and leave remaining port unconnected (exposed to ambient pressure).
Differential Pressure readings will read as positive pressure when the center port has the higher pressure of the two ports.
The 18 inch leads on all P400 Pressure Sensors may be extended up to 100 FT (30 meters) by the user using three conductor 22 or 24 gage cable. In electrically noisy environments we recommend using shielded cable.
Because the P400 is small and light, it can be held in place by fixing the signal cable and pressure tubing with a cable tie or hook and loop straps about an inch or so from the pressure ports. A mounting base is also available (below).
Sensor press fits into base. Neoprene rubber pads grip sensor securely. Base has two 0.184 dia mounting holes spaced 1.375 inches center to center. Maximum temperature rating of base: 75°C (167°F)
