Mixing components with older 7200 series or non-XL legacy systems can alter the electrical characteristics and calibration, leading to inaccurate gap voltage readings.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the purpose of the 304 stainless steel sleeve combined with the aluminum body?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: The aluminum body provides a lightweight, spark-resistant, and corrosion-resistant outer enclosure, while the 304 stainless steel sleeve delivers superior mechanical rigidity and wear resistance where the assembly penetrates the machine casing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does this housing assembly maintain its hazardous area rating if alternative fittings are used?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: No. The explosion-proof integrity is only guaranteed when using the factory-supplied explosion-proof fittings or certified equivalents torqued to exact regulatory standards.

Adjust the probe depth until the voltage reads exactly -10.0 VDC (corresponding to the center of the linear range for standard calibrated targets), then secure the mounting locks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNPT Thread Sealing and Torque:\u003c\/strong\u003e Apply a high-grade, electrically conductive anti-seize compound or Teflon tape to the 3\/4-14 NPT mounting threads. Thread the assembly into the casing hand-tight, then wrench-tighten an additional 1.5 to 3.0 turns to ensure an explosion-proof, gas-tight seal. Do not over-torque, as this can distort the stainless steel sleeve.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConduit Sealing and Moisture Prevention:\u003c\/strong\u003e Ensure the explosion-proof conduit fitting is filled with approved sealing compound after routing the probe extension cable. Route the external conduit with a low-point drip loop to prevent ambient moisture and condensation from draining into the aluminum enclosure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSevere Environment Durability:\u003c\/strong\u003e This assembly is engineered to withstand high-frequency structural vibration typical of large centrifugal compressors and steam turbines.
