For penetration lengths between 1.0 and 2.0 inches, counter boring the machine case may be necessary to reduce side or rear view effects. If the combined penetration (C plus D) exceeds 300 mm (12 in), sleeve support near the probe is required to prevent resonance.\u003c\/p\u003e\u003ch2\u003eIndustry Applications\u003c\/h2\u003e\u003cp\u003eThis housing assembly is ideal for vibration monitoring on turbines, compressors, pumps, and other rotating equipment where shaft displacement must be measured accurately. In a typical refinery application, the 21000-16-10-15-081-03-02 mounts externally on the machine case, protecting the proximity probe while providing a reliable signal to the monitoring system. Its CSA Type 4 enclosure rating and explosion-proof certification (Class 1 Divisions 1 and 2, Groups C and D; Class 2 Divisions 1 and 2, Groups E, F, and G) make it suitable for hazardous areas.\u003c\/p\u003e\u003cp\u003eFor maintenance teams, this assembly simplifies probe installation and replacement. The dome cover and threaded ports allow easy conduit connections, while the optional standoff adapter accommodates various mounting configurations. The included fittings ensure a secure, leak-proof seal, reducing the risk of contamination and downtime.\u003c\/p\u003e\u003ch2\u003eInstallation \u0026amp; Setup Guidance\u003c\/h2\u003e\u003cp\u003eProper installation is critical for accurate measurements.

Check the O-rings and thread seal periodically for wear, especially in high-vibration environments. Verify that the dome cover remains securely tightened and that all fittings are free from corrosion. The aluminum body and stainless steel sleeve resist environmental degradation, but regular cleaning of the exterior helps maintain the enclosure rating.\u003c\/p\u003e\u003cp\u003eBecause this assembly is CSA certified for hazardous areas, any maintenance must be performed with the power removed and in accordance with local regulations. Replacing worn grommets or fittings promptly prevents moisture ingress and maintains the non-incendive circuit integrity.\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eWhen ordering the 21000-16-10-15-081-03-02, confirm that the suffix codes match your application requirements. The probe option (16) specifies the 3300 XL 8 mm probe, which is a standard choice for many machines. The cable length (10) of 1.0 m suits most installations, but longer cables may be needed for remote monitoring. The standoff adapter (15) and probe penetration (081) must be selected to position the probe tip correctly relative to the shaft.\u003c\/p\u003e\u003cp\u003eVerify that your system is compatible with the 8 mm probe format and that the mounting thread is correct. If you have any doubts, consult the manufacturer's documentation or contact a technical specialist.
