Expert FAQ & Purchasing Tips

Q: Why does the 24701 model require a standoff adapter for this penetration?
A: The 2.0-inch standoff (Option -20) provides the necessary mechanical clearance for the housing to clear external machine insulation or cooling fins while maintaining the 6-inch sleeve depth.

Q: Does this specific part number include the proximity probe?
A: No. Suffixes -00-00 indicate “Probe not required.” This assembly is the protective hardware; the sensor must be selected based on your monitoring system (e.g., 8mm or 11mm).

Q: How do I select the correct mounting thread?
A: This unit uses 3/4-14 NPT (Option -02). Always match your machine casing port threads or use a certified adapter to ensure an explosion-proof seal.

Q: Can the sleeve be shortened in the field?
A: Field modification is not recommended as it may damage the thread seal or internal alignment. It is best to order the exact penetration length (060 = 6 inches) for your application.

Q: Is the dome cover compatible with conduit fittings?
A: The dome cover protects the probe head. Conduit connections are made through the threaded ports on the housing body, ensuring wires are protected from moisture and debris.
