The 0.5 m cable length is well-suited for close-coupled installations where the probe connects to a nearby extension cable or monitor.\u003c\/p\u003e\u003ch2\u003eInstallation \u0026amp; Setup Guidance\u003c\/h2\u003e\u003cp\u003eBefore installation, verify that the mounting thread (3\/4-14 NPT) matches your machine's existing port. The included cable seal grip accommodates cable diameters from 1\/8 to 3\/8 inches, ensuring a secure and weatherproof entry. Tighten the dome cover and fittings to the manufacturer's recommended torque to maintain the explosion-proof seal.\u003c\/p\u003e\u003cp\u003eFor optimal performance, position the probe so that the sensing tip is at the correct gap relative to the target surface. Use the visible probe markings (if present) to confirm proper penetration. If the probe is not visible, rely on the mechanical stop and measured dimensions to set the gap.\u003c\/p\u003e\u003ch2\u003eMaintenance \u0026amp; Reliability\u003c\/h2\u003e\u003cp\u003eRoutine inspection of the housing assembly every 6 to 12 months is recommended to check for loose fittings, damaged O-rings, or signs of corrosion. The aluminum body and stainless steel sleeve resist most industrial atmospheres, but in highly corrosive environments, more frequent checks may be necessary.\u003c\/p\u003e\u003cp\u003eBecause the assembly is designed for easy access, replacing the probe or O-rings is straightforward, minimizing downtime. The robust construction and CSA Type 4 rating contribute to a long service life, reducing total cost of ownership.\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eWhen ordering a replacement, confirm the exact part number \u003cstrong\u003e21000-16-05-00-066-03-02\u003c\/strong\u003e to ensure compatibility with your existing system.
