Sensonics offers a range of instrumentation for Hydroelectric Machines which provide the operator critical information on both turbine and generator performance.

Our vibration sensors offer both piezoelectric and electrodynamic velocity sensing options, as well as a range of proximity probes for the measurement of guide bearing vibration at slow rotational speeds, stator vibration and thrust bearing position.

Generator stator and rotor air gap analysis is a key parameter to be monitored, particularly on larger machines. Sensonics CS range of air gap sensors provides a measurement range of up to 75mm providing both dynamic and processed gap outputs.

Sensor signal conditioning can be performed with our Sentry G3 supervisory system, or our DN26G3 monitor, which is popular on smaller installations and specifically designed with low-frequency vibration algorithms suited to hydroelectric installations.
