Application of pressure transmitter of ceramic measuring unit in industry

The pressure transmitter of ceramic measuring unit is mainly used in equipment machine tools in industry, which has the following points:

1. accurate linear 4...20 mA output signal

2. High repeatability and low linear error

3. High load protection and long-term stability

4. Solid stainless steel shell, suitable for harsh industrial environment.

5. Wide working temperature range

Common pressure transmitters with ceramic measuring units are: Yifumen PA3024.

Analysis on the misunderstanding of selecting pressure transmitter

A good quality pressure transmitter not only has excellent functions, but also has little deviation in its own system, and its anti-interference ability is relatively strong, which has a major influence on the measurement of pressure transmitter. However, in the actual use, the user's choice of pressure transmitter is often easily misunderstood, and these misunderstandings will also affect the user's choice. In order to prevent these misunderstandings accurately, users need to have a certain understanding of the selection misunderstandings of pressure transmitters.

1. Admire foreign things, buy expensive ones, and think that expensive ones must be good.

2. Don't listen to the manufacturer's statement completely. Stop thinking about its products and see if they are as good as they say.

3. Review the material of pressure transmitter. Many transmitter manufacturers in China use LM324 (or LM258) and LM431, which can be used as remote control toys, to make pressure transmitters. As the service life of pressure transmitters is long, it is necessary to review the material of pressure transmitters when purchasing.

4. The products of Engraving were selected, such as voltage output type instead of current output type, non-scale output type instead of 4 ~ 20mA scale output type, and Engraving 3-wire 4-wire output type instead of 4 ~ 20mA scale two-wire output type.

5. The transmitter is a frontier subject, and many project planning staff are unfamiliar with it. They mistakenly think that the sensor transmitter is very complicated. The actual transmitter is composed of a receiver, a transmitter module and an operational amplifier.

Through the brief description of the above process, trust experts should have an accurate understanding of how to accurately choose pressure transmitters, and also understand how to avoid these misunderstandings.
