Temperature Transmitter with 4-20mA Hart for Thermocouple Rtd

Product Description

Temperature transmitter with 4-20mA Hart for thermocouple RTD

Product Description

The on-site thermal resistance or thermocouple signals are isolated and amplified, converted into DC signals that are linear with temperature, and output to the control system. When used for thermocouple temperature transmission, it has the function of automatic compensation for cold junction temperature. The supporting upper computer software can be used for parameter modification, which can be used in conjunction with unit combination instruments, DCS, PLC and other systems to provide on-site instrument signal isolation, signal conversion, signal distribution, signal processing, etc., thereby improving the anti-interference ability of industrial production process automatic control systems and ensuring the stability and reliability of the system. This product is divided into one in one out and two in two out varieties, and the input and output are magnetically isolated.
