Why does 4~20mA 2-wire Become Mainstream Output of Transmitter

With respect to transmitter signal transmission in industrial automation applications, 4~20mA is one of the most common choice. In the case there will be a linear relationship between the process variable( pressure, level, temperature, etc.) and the current output. 4mA represents lower limit, 20m... Read More

What is thermowell?

When using a temperature sensor/transmitter, the stem is inserted into the process container and exposed to the measured medium. In certain operating conditions, some factors could causing damage to the probe, such as suspended solid particles, extreme pressure, erosion, corrosion and degradation... Read More

How does Display Controller Work as Secondary Instrument
