GTM104 RTD 4 20ma pt100 temperature transmitter
Description
GTM104 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).

Features
1. GTM104 adopts circuit design with lightening protection and EFT resistant function, thus the product is lightening resistant. The product could protect related equipment effectively under 5 continuous inductive thunder (≤±4000V).
2. Both input and output could resist ±4000V EFT interference.
3. GTM104 RTD transmitter could effectively protect equipment damage from faradism, switch on and off of high capacity equipment in power system, line fault, switching, operation of frequency conversion equipment or welding machine, etc.
4. Product with compact structure design and easy for installation.
5. Super low consumption inner circuit design will greatly reduce temperature drift caused by heat dissipation of instrument components. This had improved long period stability of the product and prolonged its service life.
6. Operating temperature range for the product is -40~+85℃. GTM104 RTD transmitter could operate under harsh environment.
