In the field of hydroelectric turbines and in an environment requiring fully submerged measuring probes, MC-monitoring has developed the Submersible Proximity Probe (SPP).
The SPP is an Eddy current proximity probes used for non-contact measurement of shaft vibration and position.
The high-performance casing probe material allows sealed mounting of the eddy current probe into water or oil lubricated bearing types.
Front and back of the sensor are sealed. This gives a protection rating of IP69 and may resist a pressure up to 10 bars. Beside excellent wear resistance and high dimensional stability, the SPP presents an accuracy of reading better than +/- 2% on measuring range.
The SPP series is currently available for a measuring ranges of 0..2 mm (SPP-201) or 0..4 mm (SPP-401).
