Installation
CAUTION:
1.INCORRECT ELECTRICAL CONNECTIONS CAN, IN CERTAIN CIRCUMSTANCES, DESTROY THE ELECTRONIC OUTPUT CIRCUIT.
2.BEFORE APPLYING ELECTRICAL POWER, MAKE SURE THE SUPPLY VOLTAGE IS TO THE CORRECT RATING.
3.THIS A VERY SENSITIVE SENSOR. ONLY APPLY PRESSURE WITHIN THE PRESSURE RANGE.
Mounting
Two M5 threaded holes in the base of the sensor provide mounting points.
Note: The screws must not enter the holes more than 0.472" into the sensor body.
The installed position of the sensor should be away from sudden temperature variations, shocks and vibrations and should not be close to strong electromagnetic fields (transformers, motors etc.). The sensor can be mounted in any position, but mounting at an angle may require zero adjustment.

Electromagnetic Interference
To avoid electrical interference, use shielded cable with the shield connected to the earth ground at both ends. The ground of the sensor can be the casing or the ground terminal screw.
Electrical Connections
PX838 Series (current output)
The maximum allowable load resistance is calculated to
formula:
R Max = 0.05 (V supply - 10) kW Where: R Max in kW and V in Volts

If the output cable passes through an area of electrical
disturbance, use a recommended load impedance of between 2 kW and 10 kW . Connect the load resistance between the wires corresponding to signal and - terminal at
a point furthest from the sensor; this produces a circulating
current.
