Temperature Transmitters for Thermocouples Our thermocouple transmitters offer very high accuracy and linearity, accurate built-in cold junction compensation, reverse polarity and surge protection, thermocouple failure detection and failsafe output. They can be mounted in the head of the thermocouple housing or on a 35 mm DIN rail. GTT202 is a field programmable two wire loop power 4-20 mA temperature transmitters for most of the thermocouples in use and millivolts. Features OUTPUT CAN BE LINEAR TO TEMPERATURE OR VOLTAGE, FIELD PROGRAMMABLE TOTAL ERROR IS LESS THAN 0.1 % FS BUILT-IN COLD JUNCTION COMPENSATION. CAN BE ENABLED OR DISABLED, FIELD PROGRAMMABLE COLD JUNCTION COMPENSATION ERROR LESS THAN 0.25 oC FIELD PROGRAMMABLE THERMOCOUPLE TYPE DEGREES C OR DEGREES F, FIELD PROGRAMMABLE THERMOCOUPLE FAILURE DETECTION FIELD PROGRAMMABLE FAILSAFE OUTPUT THE OUTPUT IS FIELD PROGRAMMABLE - OFFSET/SPAN, NORMAL/INVERSE REVERSE POLARITY AND SURGE PROTECTION HEAD MOUNT OR DIN RAIL MOUNT 44.4 mm dia x 15 mm H (1.75''dia x 0.6''H), HEIGHT INCLUDES THE TERMINALS WEIGHT 20 g (0.7 oz) GpH140-12 has one input for pH / REDOX / ORP and one for mV / thermocouples. GpH140-22 has two inputs for mV / thermocouples. Both have as a standard one Pt1000 RTD input, the built-in cold junction compensation and one 4-20 mA two wire loop power input.
