Overview:

The on-site thermal resistance or thermocouple signal is isolated and amplified, converted into a DC signal linear to the temperature and output to the control system. When used as a thermocouple temperature transmission, it has the automatic cold junction temperature compensation function.

It can be used in combination with the unit combination instrument and DCS, PLC and other systems to give field instrument signal isolation, signal conversion, signal distribution, signal processing, etc., thereby improving the anti-interference ability of the automatic control system in the industrial production process and ensuring the stability and reliability of the system Sex. With LCD display, the parameters of different channels can be displayed by touching the infrared touch buttons, and the real-time measured value, theoretical output value, unit and channel number can be displayed.
