Follow these steps for best results:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSelect a mounting location that provides a clear line of sight to the target shaft surface. Ensure the probe tip is perpendicular to the shaft.\u003c\/li\u003e\n\u003cli\u003eUse the 3\/4-14 NPT thread to secure the housing into the machine case. If the probe penetration length (C plus D) is between 1.0 and 2.0 inches, counter boring may be necessary to reduce side view or rear view effects.\u003c\/li\u003e\n\u003cli\u003eFor probe penetration lengths exceeding 300 mm (12 in), add sleeve support near the probe to prevent resonance.\u003c\/li\u003e\n\u003cli\u003eRoute the probe cable through the cable seal grip, selecting the appropriate grommet size from the provided range (1\/8 to 3\/8 inches).\u003c\/li\u003e\n\u003cli\u003eConnect the probe to the extension cable and monitor as per your system's wiring diagram.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAdjust the probe penetration (Option D) within the 13 mm (±0.5 in) range to achieve the optimal gap voltage. Always verify that the probe tip does not contact the shaft during operation.\u003c\/p\u003e\u003ch2\u003eMaintenance \u0026amp; Reliability\u003c\/h2\u003e\u003cp\u003eRoutine inspection ensures long-term performance. Check the housing for any signs of corrosion or damage, especially in corrosive atmospheres. The aluminum body with 304 stainless steel sleeve provides excellent resistance, but regular cleaning is recommended.\u003c\/p\u003e\u003cp\u003eInspect the cable seal grip and grommets periodically to maintain a watertight seal. Replace worn grommets to prevent moisture ingress. Verify that all fittings remain tight to avoid loosening due to vibration.\u003c\/p\u003e\u003cp\u003eThe housing is rated for temperatures up to +80 °C (T4 rating) and down to -50 °C, making it suitable for extreme environments. With proper care, this module will provide years of reliable service, reducing downtime and maintenance costs.\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eBefore ordering, confirm that the \u003cstrong\u003e21000-16-05-00-105-03-02\u003c\/strong\u003e matches your system requirements.
