18-811IS Thermocouple Transmitter, FM Approved and Intrinsically Safe

FM Approved, Intrinsically Safe T/C Input (Choose T/C Type & Range) Factory Calibrated +/- 0.1% Accuracy Low Cost Conversion of thermocouple from field sensors may be accomplished using the DEVAR Model 18-811IS series of connection head mount, signal transmitters. The 18-811IS's compact size allows it to mount directly within thermocouple connection heads, providing a 4/20 mA output signal proportional to the milli-volt input signal. Operational errors are eliminated by mounting the amplifier close to the thermocouple within the connection head. These errors, due to multiple TC cold junction connections, noise pickup, and possible voltage drops are not encountered because a stable 4/20 mA signal is transmitter directly from the TC assembly. Each unit is supplied precalibrated to standard temperature ranges for thermocouple signals. Utilization of multi-turn trimmers for span and offset calibration (±25% adjustment) enable precise 0.1% calibration. Typical applications include i
