GTM100 slide switch RTD temperature 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.
FEATURES
PRODUCT DESCRIPTION
GTM100
1. GTM100 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. GTM100 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℃. GTM100 RTD transmitter could operate under harsh environment.
