Mounting the Sensor

Installing extended mount electronics

If you ordered a sensor with an extended mount for the electronics, you will need to install the extender. To install the extended mount electronics:

1.There is a metal clamping ring around the base of the feedthrough (Figure 9). Remove this ring and set it aside. You will use it later to secure the extender to the sensor.

2.The sensor was shipped with a plastic cap over the feedthrough pins. Remove the plastic cap and discard it.

3.There is a plastic plug inside the extended mount (Figure 10). Remove the plug and discard it.

4.Place the extended mount onto the feedthrough and carefully rotate the extender until the feedthrough notches line up. Being careful not to damage the feedthrough pins, push the extender down onto the feedthrough until it is fully engaged.

5.Replace the clamping ring on the feedthrough. Tighten the ring’s screw to 13–18 in-lbs (1.5–2 N-m).
