Isolated temperature transmitter

1 Introduction edit

Isolation temperature transmitter is a kind of advanced digital technology. It has excellent performance in suppressing high and low frequency interference signals. It can be reliably applied even in high-power frequency conversion control systems. It uses digital calibration internally and has no zero point. And full-scale potentiometers, automatic dynamic calibration zero, automatic temperature drift compensation and many other advanced technologies, and meet the IEC61000-4-4: 1995 in the fourth category (bad industrial site) environment for the product's anti-electromagnetic interference requirements, The application of this technology ensures the stability and reliability of the product.
