As an integral component of the 3300 XL 8 mm Transducer System, this reverse-mount probe features a 3\/8-24 UNF threaded case, physical fluid sealing, and robust physical construction to withstand continuous exposure to extreme industrial environments. It translates physical gap changes into proportional voltage signals when coupled with a calibrated 3300 XL Proximitor Sensor, allowing plant operators to identify machinery instability before failure occurs.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul style=\"list-style-type: square;

Standardizing on the 3300 XL 8 mm system provides backwards compatibility with older 3300 series 5 mm and 8 mm components; however, using mixed legacy configurations will alter the output scale factor from the typical 7.87 V\/mm (200 mV\/mil).

A common point of commissioning failure is over-tightening of the probe thread, which can deform the internal sensor housing or damage the PPS tip.

The coaxial cable routing must avoid sharp bends; the minimum bend radius of 25.4 mm (1.0 inch) must be strictly maintained. When joining the ClickLoc connectors, ensure no solvent, oil, or physical debris enters the connection face.
