ABSTRACT:
Disclosed is a differential temperature cell useful for measuring the difference in temperature between two environments. This dT cell comprises a first reservoir which is in fluid communication with a first chamber. Part of one wall of the first chamber defines a diaphragm, which also forms a part of the wall of a second chamber. The diaphragm provides a structure for measuring differences in pressure between the two chambers. The second chamber is also in fluid communication with a second reservoir.
