Proximity Probes Snoop Into Hazardous Areas


SENSONICS reports that its SENTURION X Range of proximity probe systems have obtained ATEX, IECEx and PESO certification. Compliant to the API 670 standard, these intrinsically safe probes are suitable for non-contact measurement of shaft vibration position, position and speed in hazardous areas where potentially explosive gases or dusts are present. Typical applications include monitoring reciprocating machines such as turbines, pumps, compressors, fans, motors and gearboxes across a wide range of industries including petroleum refineries, petrochemical and power generation plants.

Said to be versatile, the eddy current proximity probes can be used for many critical measurements such as relative shaft vibration and eccentricity, axial shaft position, thrust wear, differential expansion, shaft speed, over-speed, phase reference, reverse rotation, and rod drop monitoring (rider band wear on reciprocating compressors). Measurement ranges are from 2.5 mm to 30 mm. The probes are available in different formats including reverse mount, for use in externally fitted through case probe holders, straight threaded usually mounted internal to the machine and disc type which are typically mounted on an adjustable bracket for axial measurements.

They can be supplied with plain cables or armored with stainless steel convoluted hose, and with extension cables where required. System cable lengths are 5m, 7m, or 9m, and the driver unit can be configured at the factory to suit the application. For more details, checkout the SENTURION X Range of proximity probe systems.
