Technical characteristics

This product adopts advanced digital technology, which possesses many advanced performances that traditional analog instruments do not possess. It has excellent performance in suppressing high and low frequency interference signals. It can be reliably applied even in high power frequency conversion control system. At the same time, the application of digital technology thoroughly overcomes the disadvantage of poor linearity of traditional temperature transmitter, and the number is used internally. Many advanced technologies, such as character adjustment, zero-free and full-degree potentiometer, automatic dynamic calibration zero point, automatic compensation for temperature drift, etc., meet the requirements of anti-electromagnetic interference for products in the fourth category (harsh industrial field) environment stipulated in IEC 61000-4:1995. The application of these technologies ensures the stability and reliability of products scientifically.

The above technologies are superior to the advanced international standards.

Applicability

It can be used in combination with unit instrumentation, DCS, PLC and other systems. It is widely used in oil field, petrochemical, manufacturing, electric power, metallurgy and other major projects.
