While fiberglass offers superior chemical resistance in highly acidic environments, the aluminum 21000 variant is preferred on high-temperature casings and applications prone to direct mechanical impact. When transitioning legacy 7200 series installations to 3300 XL proximity systems within this housing, verify that the sleeve thread pitch matches the probe body configuration.\n\u003c\/p\u003e\n\n\u003ch4 style=\"color: #1a365d; font-size: 16px; margin-top: 1rem; margin-bottom: 0.5rem;\"\u003eApplication Pitfalls \u0026amp; Engineering Notes\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003e\nDuring machinery operation, significant thermal expansion of the machine casing can cause the housing's insertion depth to shift relative to the shaft target area. In high-temperature steam applications, commissioning engineers must calculate the thermal growth vector to ensure the probe remains within its linear calibration range (typically 80 mils for standard 8mm probes) when the machine reaches steady-state operating temperature.\n\u003c\/p\u003e\n\n\u003ch4 style=\"color: #1a365d; font-size: 16px; margin-top: 1rem; margin-bottom: 0.5rem;\"\u003eCommissioning \u0026amp; Calibration Tips\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003e\nNever rotate the housing assembly while the probe cable is connected, as this twists and damages the internal coaxial cable. Always disconnect the extension cable before making physical sleeve depth adjustments. Utilize a static calibrator spindle or dial indicator during initial mechanical gap setup to verify that the target DC voltage reading matches the correct physical gap midpoint.\n\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cdiv style=\"background-color: #fff5f5; border-left: 4px solid #c53030; padding: 1rem; margin-bottom: 1.5rem;\"\u003e\n  \u003cstrong style=\"color: #9b2c2c; display: block; margin-bottom: 0.5rem;\"\u003eCRITICAL WARNING\u003c\/strong\u003e\n  \u003cp style=\"color: #9b2c2c; margin: 0; font-size: 14px;\"\u003e\n    Ensure all machine systems are locked out, depressurized, and completely de-energized before mounting or adjusting the probe housing. Escaping high-pressure steam, hot oil, or process gases can cause catastrophic injury.
