Description temperature transmitter
GTM100 slide switch RTD transmitter is an intelligent two-wire PC programmable RTD transmitter with its range set by slide switch. It could linearize RTD input for 4-20mA (two-wire) output and transmit the output signal to system control equipment like DCS or PLC with features of sensor damage or short circuit preset. The product is powered by output circuit (no separate power needed) and shall be installed in junction box of temperature sensor. Installation opening is in cylinder shape for fitting different size of junction box. With installation frame, GTM100 could also installed on DIN rails.
