The Bently Nevada 330172-00-20-05-02-CN addresses these with its armored cable and robust PPS tip. For example, in steam turbine vibration monitoring, the probe's high tensile strength (222 N) prevents lead-breakage under vibration. The probe's low sensitivity to 60 Hz magnetic fields (0.0014 mil pp\/gauss at 50 mil gap) ensures accurate readings even near electrical machinery. To prevent premature pressure seal failure, avoid exposing the probe below -34°C.\u003c\/p\u003e\u003ch2\u003eInstallation \u0026amp; Setup Guidance\u003c\/h2\u003e\u003cp\u003eProper mounting is critical for accurate measurements. The Bently Nevada 330172-00-20-05-02-CN uses a 1\/4-28 UNF thread with a maximum thread engagement of 0.375 inches. When drilling and tapping, use a #3 or larger tap drill. Apply a probe case torque of 5.1 N·m (45 in·lb); do not exceed 7.3 N·m (65 in·lb). For the ClickLoc connector, the maximum connector-to-connector torque is 0.565 N·m (0.42 ft·lbf). Ensure the cable bend radius does not drop below 25.4 mm to avoid internal damage.\u003c\/p\u003e\u003ch2\u003eMaintenance \u0026amp; Reliability\u003c\/h2\u003e\u003cp\u003eRoutine inspection of the probe tip and cable is recommended. The probe operates reliably from -35°C to +177°C. To maintain pressure seal integrity, avoid operation below -34°C. The gold-plated connectors resist corrosion, and the stainless steel case provides durability in harsh environments. Following the specified torque limits prevents mechanical stress.\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eWhen selecting a replacement or upgrade, verify the probe length (0.5 m as configured here) and thread compatibility. This unit includes a miniature coaxial ClickLoc connector. For system integration, ensure your monitor supports -24 Vdc excitation and 50 Ω output resistance.
