Convert High-Temperature Thermocouple Signals Reliably Thermocouple Temperature Transmitter is designed for furnaces, kilns, exhausts, reactors and machinery requiring broad or high temperature range. Small millivolt signals are vulnerable to wrong extension wire, reversed polarity, electrical noise and cold-junction error. A transmitter near the sensor performs linearization and cold-junction compensation before sending a stronger 4-20 mA or digital signal. Match Type, Polarity and Protection Tube The transmitter accepts an RTD or thermocouple signal, performs linearization and compensation, and converts the result into a robust 4-20 mA or digital output for the control system. Locating the transmitter close to the sensor reduces noise over long cable runs. Gallop lists RTD and thermocouple inputs, 4-20 mA, voltage, RS485 and HART options, accuracy choices of ±0.25 or ±0.5 percent, and IP65 or IP67 housings. The portfolio also includes hazardous-area configurations and a range of protection-tube materials. Gallop lists common K, E, S and B ranges in the temperature portfolio, with final limits set by sensor, sheath and protection-tube construction. This page can naturally support buyer terms such as temperature transmitter, 4-20 mA temperature signal, RTD transmitter, thermocouple transmitter and hazardous-area temperature measurement. Control Cold Junction and Installation Error Specify thermocouple type, range, junction, sheath, insertion length, thermowell or protection tube, ambient temperature and response requirement. Use matching extension cable, verify polarity from sensor to transmitter and configure burnout direction and alarm behavior for a safe process response. The final loop accuracy includes sensor tolerance, transmitter error, installation effects and drift. Thermocouple polarity, cold-junction compensation, RTD lead resistance and thermowell lag must be addressed during design and commissioning. Gallop states a one-year warranty, long-life maintenance and installation guidance. Include commissioning support, spare-part recommendations and response expectations in the commercial review so service terms are as clear as the instrument specification.
