  • This product is a precision platinum resistance temperature transducer. The transducer converts the resistance signal of the input platinum resistance to the standard 420mA DC current output through constant current source excitation, voltage magnification, linear processing. The input temperature range can be confirmed by the user when ordering. The standard three-wire connection is adopted between platinum resistance and transducer, can compensate for the adverse effect of long leads on temperature measurement accuracy. The output is two-wire connection, signal circuit under its own power, low power consumption; High output impedance, large-signal, non- radio-frequency interference effects, the signal has a strong far eastone ability. With the power supply polarity reverse protection circuit. This product is small,nice linearity,low temperature drift,high accuracy in temperature measurement, stable and reliable performance, it can be used in various temperature measuring environment.
