Ultimate equipment for bearing temperature monitoring
The SENTRY® wireless bearing temperature monitoring system is capable of continuously measuring the metal temperature of bearings during engine operation. Each sensor is individually interrogated from a multiplexed signal
processing unit using a high frequency and low energy radar pulse.
The radar pulse is transmitted to the wireless sensor via a coaxial cable to a stationary antenna positioned inside the crank case. Within the interrogation range of the stationary antenna
the sensor responds to the radar pulse by reflecting a pulse pattern back to the signal processing unit. The characteristics of the reflected pulse is uniquely defined by the temperature.
