Title: Temperature converting circuit for three-wire type resistance temperature detector
Inventor: YASUDA HIROO
IPC: G01K7/20
Filed: 1990-06-22
Abstract: PURPOSE:To correct a nonlinear error without causing any span variation nor zero variation and to reduce an error due to a leak current by providing a constant current control circuit which has the inflow point of the resistance temperature detector held at a ground potential. CONSTITUTION:A leak current due to insulation deterioration between the resistance temperature detector Rt and ground, and a conductor L1 and the ground causes and error and the leak current increases more and more as the potential between them is higher, but the potential at the inflow port of the resistance temperature detector Rt is low since the resistance value is small. Further, a current flowing to the inverted input terminal of an operational amplifier A1 can be ignored by using high-input resistance. The span variation of a line resistance L is the ratio of the sum of the input resistance and feedback resistance of an operational amplifier A2 and the line resistance L. For the purpose, resistances R4 and R6 which are large are selected to reduce the variation.
