<1>. QDL80A digital display thermocouple thermometer is composed of a temperature sensor and a signal converter. The signal converter is installed in the cold junction box of the temperature sensor, and directly converts the voltage and resistance signals detected by the temperature sensor into a 4-20mA current output.
<2>. The structure is simple, easy to install, use and maintain. It is a new generation of temperature detection and control instrument, which is well received by designers and users. <3>. At present, it has been widely used in petroleum, chemical,metallurgy, power station, light industry and other departments, and is used with regulators, recording instruments, computers,etc. to form various measurement and control systems.
