Temperature Sensor of Current Transmission Circuit
The resistance in the cirtuit is metal film one. Itsaccuracy is better than 1% and temperature coefficient TCis less than ±50X10-6/K.The measuring range is from0℃ to 100℃. Current I= 4+T/6.25. The temperate unit is ℃ and the current unit is mA. The current shows KTY87two-wire current transmitter consisting of Wheatstone bridge with pre-amplifier , current transmitter stage and voltage regulator.
