Applications and Use Cases

The 173688-01-20-12-05 excels in monitoring turbines, compressors, pumps, and motors. It provides continuous shaft vibration and position data that helps operators assess machine health. In petrochemical plants, the ATEX and IECEx approvals allow safe use in explosive atmospheres. Similarly, the CSA certification supports deployment in Canadian and US industrial sites. This probe is also suitable for paper mills, power generation, and oil refineries where reliability is paramount.

Installation and Setup

Proper installation is critical for accurate readings. The 1/2-14 NPT mounting thread ensures a secure fit into standard probe ports. Ensure the probe tip is positioned correctly relative to the shaft surface. The 2.0-meter system length provides flexibility in routing cables to the monitor. Follow the manufacturer's guidelines for gap settings and calibration. Always verify the connector is fully seated to avoid signal loss.

Maintenance and Reliability

Regular inspection of the probe and cable helps maintain measurement integrity. Check for physical damage or wear on the tip and cable. The stainless steel case and PPS tip resist corrosion and abrasion. Although the probe is designed to seal differential pressure, it is not pressure tested before shipment. If your application requires a pressure seal test, contact the custom design department. Follow the manufacturer's manual for any cleaning or handling procedures.

Comparison with Similar Probes

Compared to other 3300 XL 8 mm probes, the 173688-01-20-12-05 offers a specific combination of options. The 2.0-meter system length is a common choice for many installations.
