Abstract
A fluid temperature measuring device, which includes a resistance temperature detector (RTD), is disclosed for measuring the temperature of a fluid flowing through one of several heat exchange conduits which empty into a channel of a heat exchanger of a refrigeration system. The device is simple, inexpensive, reliable, easy to replace, and may be used with a microprocessor control system for the refrigeration system.
Claims5
A device for measuring the temperature of a fluid flowing through one of several heat exchange conduits which empty into a collection chamber comprising:
- temperature sensing means for generating electrical signals corresponding to the temperature of the fluid in contact with the temperature sensing means in the collection chamber;
- and
- diverter means for directing the fluid from the one conduit whose fluid temperature it is desired to measure into the collection chamber to contact said temperature sensing means substantially only with fluid from this one conduit.
