Industry Applications and Failure Prevention
By maintaining a sealed environment around the probe tip, it prevents contamination from moisture, dust, and debris—common failure points in vibration monitoring systems. The 303 stainless steel body and 304 stainless steel sleeve offer corrosion resistance in chemical and offshore environments.

Installation and Setup Guidance
When installing the 24701-28-05-00-140-00-02, ensure the mounting thread (3/4-14 NPT) is properly sealed with appropriate thread sealant to prevent leakage. The probe sleeve length of 14 inches (probe penetration) must be matched to the machine casing thickness. The dome cover screws into the housing body; verify O-ring condition before final tightening. Conduit connections should be made to the threaded ports using approved fittings (not included).
Maintenance and Reliability
Periodic inspection of the housing assembly is recommended to check for O-ring degradation, corrosion, or physical damage. The stainless steel construction provides long service life, but environmental factors such as high humidity or chemical exposure may accelerate wear. Replace O-rings if any signs of cracking or compression set are observed.
