Performance Parameters The ETR probe maintains the same electrical performance as standard 3300 XL 8mm probes across the extended temperature range. The linear range is 2.0 mm (80 mils) with system linearity of ±0.025 mm (±1.0 mil). When combined with the 3300 XL 8mm ETR Proximitor and ETR extension cable, the system achieves the same 7.87 V/mm (200 mV/mil) sensitivity as the standard system. The probe maintains calibration stability within ±1.0% across the full temperature range. The frequency response extends to 10 kHz when used with the ETR Proximitor.
Material Composition The probe tip is molded from Polyphenylene Sulfide (PPS), a high-temperature engineering plastic with excellent dimensional stability and chemical resistance. The probe case is machined from AISI 303 or 304 stainless steel for corrosion resistance and mechanical strength. The internal coil is wound with high-temperature magnet wire on a ceramic or high-temperature plastic bobbin. The cable conductor is silver-plated copper with high-temperature fluoropolymer insulation. The Viton O-ring provides reliable pressure sealing between the probe tip and case across the temperature range.
Structural Characteristics The probe features a cylindrical stainless steel case with M10x1 external thread. The 0mm unthreaded length means the thread extends to the probe tip, suitable for flush mounting. The 6mm overall case length is very compact, with the threaded portion being the majority of the case. The integral cable exits from the rear of the case. The probe tip is molded PPS with a flat sensing face. The ClickLoc connector at the cable end provides positive locking with the extension cable or Proximitor. The probe is marked with part number and serial number on the case.
