Kongsberg Crosshead and crank temperature monitoring - SENTRY

Wireless bearing temperature monitoring system to continuously measure metal temperature of bearings during engine operation 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. The SENTRY®system is based on a sensor technology called Surface Acoustic Wave (SAW), which opens for non-contact wireless temperature sensing without using batteries or transmitting inductive power to the sensor. In this system the air-gap between the sensor and the stationary antenna can vary between 10 and 50 millimetres providing an extremely flexible installation inside the crank-case.
