Beskrivning
<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>. För närvarande, it has been widely used in petroleum, chemical,metallurgi, power station, light industry and other departments, and is used with regulators, recording instruments, computers,etc. to form various measurement and control systems.
