*Using XR440 set to 12 bit, or XR5-SE.

Use any Pressure Scale

The P500 Sensor can read in any unit of pressure (kPa, millibar, etc.); Simply convert the sensor's scaling values using the XR440 Pressure Converter for the XR440 or the XR5 Pressure Converter for the XR5.

Extension cable

The 18 inch leads on the P500 Pressure Sensor 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.

Power Limitation

Due to its 8 ma current draw, a maximum of 2 P500 Sensors may be powered by one XR440 Data Logger and a maximum of 3 P500 Sensors may be powered by one XR5-SE Data Logger.
