Installation and Setup

When mounting the 330171-00-40-10-02-00, drill and tap a 1/4-28 UNF hole. A #3 or larger tap drill is recommended. Apply a recommended torque of 5.1 N·m (45 in·lb) to the probe case, with a maximum of 7.3 N·m (65 in·lb). The minimum cable bend radius is 25.4 mm (1.0 in). Ensure the probe is gapped at 1.27 mm (50 mils) for optimal linear range. The probe operates with a -24 Vdc power supply and a 10 kΩ load.

Applications and Use Cases

The 330171-00-40-10-02-00 is ideal for continuous monitoring of rotating machinery, such as turbines, compressors, and pumps. Its 5mm tip and 1/4-28 thread make it suitable for tight installation spaces. The probe's PPS tip and stainless steel case provide durability in harsh industrial environments. With a temperature range up to +177°C, it can be used in high-temperature applications. The ClickLoc connector ensures secure and reliable signal transmission.
