Abstract (en)
[origin: WO0140756A2] A monitoring seal system comprises a seal housing, a seal assembly, a temperature sensor and a controller. The seal assembly sealingly engages a rotary shaft to prevent fluid leakage between the shaft and the housing. The seal assembly has at least one seal. The seal has a primary ring and a mating ring. The temperature sensor senses the temperature in the vicinity of the seal. The controller determines whether an upset condition has occured based on at least the temperature in the vicinity of the seal.
