Proximity probe systems are usually made up of a calibrated probe, extension cable and driver. Utilising the eddy current principle, this combination forms a tuned circuit with the target material and variations in probe face to target distance are detected in this circuit by the separate driver. The PRI series provides this complete functionality in a single probe assembly mounted on the machine offering either a M12 connector interface for the 5mm range probe or an integral cable for the 2mm range option.
Offering processed outputs of shaft vibration, position and speed through a 4 – 20 mA current loop, the PRI range is ideal for OEM applications and can connect directly to the local machine PLC or a plant wide DCS. The probe also provides a raw buffered output of the measured signal that can be utilised through portable analysis equipment for a more detailed picture of the dynamic performance of the machine.
