Use any Pressure Scale

A P300 Sensor can read in any unit of pressure (Pa, bar, 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 leads on the P300 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.
