Use any Pressure Scale

P450 Sensors can read in any unit of pressure (Pa, millibar, etc.); Simply convert the sensor's scaling values using the Pressure Converter for the XR440 / XR450 or the XR5 Pressure Converter.

Extension cable

The 18 inch leads on the P450 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.

Compatible tubing

Commonly available 1/8" I.D. or 3.2 mm I.D. plastic tubing is compatible with the P450 using the included tubing adapter.

Tubing stocked at Pace

Clear 3/32" I.D.  tubing connects directly to all P350, P400, P450 and P600 Sensors.  Temperature range -40°C to 74°C (-40°F to 165°F).  5/32" (4 mm) O.D., minimum bend radius 3/8" (10 mm).  Maximum pressure 43 PSI.  Available in 25 FT (7.6 meter) rolls.
