Frequently Asked Questions (FAQ)

Q: What is included in this "housing assembly"?

• A: It includes the metal housing, a pre-installed and calibrated 11mm probe, 1 meter of cable, and the connector. It is a complete, ready-to-install sensor unit.

Q: Can I adjust the probe's penetration depth after installation?

• A: No. The 7.8-inch penetration is fixed by the factory assembly. The entire housing threads in or out to set the final tip-to-target gap.

Q: Is the probe itself replaceable?

• A: In this assembly, the probe is integrated. If the probe fails, typically the entire assembly unit is replaced for guaranteed calibration.
