We have a compressor which has Four Bently Nevada Proximity Sensors P/N 330180-51-05. These are marked as Compressor Gearbox Instrumentation. These four are marked as X Probe, Y Probe, Z Probe and Speed Sensor. This compressor package will be controlled by a Local PLC. We have no idea how to interface and control these via PLC as these transducers require -17.5 to -26VDC input Power Supply and Output is also in -7.87 V/mm. Each transducer has three terminals marked as Out, COM and Vt (-24VDC). We have not used these transducers before. So i need details from an experience user regarding how to supply -24VDC power from a conventional 24VDC Power Supply, and how to interface and monitor output of these transducers to my PLC analog input Card.
Please guide me on this.
Thanks in advance.
