The DN8031 (vibration) and DN8033 (thrust position) proximity probe systems feature 4-20mA loop powered modules that can be integrated with either the local machine PLC or a plant wide DCS since it is 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 permits the adjustment of both gain and offset. 

When combined with Sensonics’ range of compact machine mounted housings, the DN803X series is suitable for smaller pumps and compressors in critical operational measurements. The driver also provides a raw buffered output of the vibration signal that can be utilised through portable analysis equipments.
