Transmitter

The transmitter is a device that converts the sensed physical quantity, chemical quantity and other information into standardized signals convenient for measurement and transmission according to certain rules, and is a component of the unit combination instrument. The transmitter can also be said to be a sensor whose output is a standardized signal.

2. Common transmitter applications

There are many kinds of transmitters. The transmitters used for industrial control instruments mainly include temperature transmitters, Pressure transmitter, flow transmitter, current transmitter, voltage transmitter, etc. Transmitters play an important role in the field of instruments, meters and industrial automation. Different from the sensor, the transmitter can not only convert non electric quantity into measurable electric quantity, but also has a certain amplification effect.

3. Transmitter development history

In the 21st century, the third generation transmitter digital intelligent transmitter has gradually entered people's vision. The third generation transmitter uses advanced detection technology to eliminate the impact of moisture, dust and other harsh on-site environment on the measurement of the transmitter, with higher accuracy. It is said that its accuracy is better than 0.05%; The range division is finer, and the range ratio is expanded to 200? 1； The stability is more than 5 years; The communication protocol is more complete. The new transmitter has also passed the safety demonstration, which can ensure the safe shutdown when the process conditions exceed the critical value. Since the second generation transmitter can meet the monitoring requirements of cement plants, and the third generation transmitter is still expensive, the author believes that it is not suitable to promote it in cement plants.
