Overview:

The two-wire 4-20mA loop supply thermal resistance temperature transmitter product is mainly used in the isolation and transmission of sensor signals such as PT100, PT1000, PT10, Cu50, Cu100 (sensor need for users themselves). The temperature is mainly used in the industry to measure the temperature of -200 ~ + 600 ° C. The transmitter has a linearization and long-term compensation function, and the factory is fully corrected according to the PT100 national standard indexing table, completely reaches 0.2 level accuracy requirements. Product separation and non-separation type. The isolation type input, the output is completely isolated, and the isolation withstand voltage of 3000 Vdc can be subjected to. Non-quarantine inputs and output are not isolated, and there is no interference. The product is installed in DIN35 international standard rail installation, small size, high precision, stable performance, high cost performance, can be widely used in oil, chemical, electric power, instrumentation and industrial control.

The WJ11 series temperature signal isolation amplifier is very convenient, only the linear resistance signal can be realized.
