Sensonics upgrades transmitters for smaller pumps, motors and compressors

1 min read

Machine protection and condition monitoring specialist Sensonics has added IECEx and UKEx intrinsically safe certification and ATEX certification to its range of Senturion X DNX803 series of transmitters designed for monitoring smaller pumps, motors and compressors in hazardous areas

The upgraded shaft vibration and axial position transmitters are approved for installation and use in areas with potentially explosive atmosphere (gases) or dusts.

The upgraded shaft vibration and axial position transmitters are approved for installation and use in areas with potentially explosive atmosphere (gases) or dusts. 

The DNX8031 (shaft vibration) and DNX8033 (shaft position) proximity probe transmitters are suitable for above ground applications when used in conjunction with Sensonics intrinsically safe range of XPR eddy current type proximity probes and XEC cables.

The 4-20mA loop powered modules provide integration with either the local machine PLC or a plant wide DCS as they are powered through the safety barrier measurement loop. All signal processing is carried out within the unit providing an output current proportional to either peak-to-peak shaft vibration or relative position to the probe face.  The module allows the adjustment of both gain and offset for ease of calibration to suit the application. 

Smaller pumps, centrifugal air compressors, motors and fans particularly benefit from the upgraded DNX803 series. When combined with Sensonics range of compact machine mounted housings, the upgraded transmitters provide a cost-effective solution for critical operational measurements, with a straightforward interface that requires no local power supply. 

The transmitter offers selectable system lengths of 5 m, 7 m or 9 m, with a front panel green LED for indicating the selected option. A gap voltage monitoring socket is also provided. The cable system incorporates snap lock connectors which require no torquing and provide a shake-proof solution important for heavy industrial applications.
