Description
BRT TC-DB11 Series Isolated thermocouple to analog current voltage signal converter is designed to deal with the temperature change measured by thermocouple (TC) through the processing circuits into a standard voltage or current signal after signal amplification. Its output signal can be used for digital temperature instrumentation recorder, analog regulator, PID, DCS system, and widely used in industrial processes detection and controlling system. BRT TC-DB11 thermocouple to analog converter can withstand 1.5kV impulse voltage among input, output, power supply, its performance is much higher than other similar TC signal converters and provides reliable high-performance solution for customers.
