Usually, the voltage signal can not be used for long-distance transmission, because its attenuation will be more serious, you can completely use the milliampere signal in transmission (this general transmitter can be), and a total of 2 transmitters are required.
The first is a thermal resistance transmitter that provides an exciting signal to the thermal resistance and outputs a current signal.
The second is the current signal converter module that converts the current signal into the voltage signal.
If it is a current signal, do not need to shield the cable, direct ordinary cable can be.
