Patent ID: 7168628

Claim:
A device for monitoring the operation of a control valve, the control valve being adapted to supply fluid at a predetermined temperature via an outlet, the device comprising: a sensor coupled to the outlet and adapted to detect the temperature of the fluid and generate data representative of the detected temperature of the fluid; a processor coupled to the sensor, the processor adapted to receive data representative of the temperature of the fluid from the sensor, determine the temperature of the fluid based on the data received from the sensor, and transmit data representative of the determined temperature to an associated indication device; an indication device communicatively coupled to the processor, the indication device adapted to receive the determined temperature data and display the determined temperature data; a storage means communicatively coupled to the processor and adapted for receiving determined temperature data from the processor and storing the received determined temperature data; and a time recording means coupled to the processor and adapted to determine the time at which a temperature was determined.
