Professional Q&A
When should I choose this long-case (230mm) probe?
Select this model when you need the probe to reach through a deep mounting hole, a heavy insulation layer, or a protective sleeve to sense the shaft.
What is the purpose of the connector protector?
It safeguards the delicate electrical contacts on the ClickLoc connector from impact, dust, and moisture during shipping, storage, and handling before final connection.
How does the 1.0-meter cable compare to shorter options?
The 1-meter length provides more routing flexibility than a 0.5m cable, often allowing connection to a junction box without needing an immediate extension cable.
Can this probe withstand washdowns or wet environments?
The probe itself is not submersible. However, its PPS tip and Viton seal offer good resistance. The connection point must be protected within an appropriate housing (e.g., Bently Nevada 31000 series) for wet areas.
What’s a common mistake when installing long-case probes?
Over-tightening. Use a torque wrench for the case thread (45 in-lb max). For the probe tip, finger tight plus a quarter-turn is sufficient—never exceed 5 in-lb.
