  Pure water machine pressure transmitter

  introduction

  With the continuous improvement of people's requirements for water quality, pure water machines have become essential household appliances for thousands of households. In a pure water machine, the pressure transmitter, as an important sensor component, plays a crucial role in real-time monitoring of water pressure and ensuring the normal operation of the equipment. This article will provide a detailed introduction to the pressure transmitter of a pure water machine, covering its working principle, classification, selection, installation and maintenance, aiming to help readers have a deeper understanding of it.

  1、 Working principle of pressure transmitter for pure water machine

  A pressure transmitter is a sensor that converts pressure signals into standard electrical signals. The pressure transmitter of a pure water machine is usually installed at the front or back end of the RO membrane to monitor pressure changes in the water circuit. Its working principle is mainly based on the piezoresistive effect, which means that the resistance value of certain materials will change with the pressure they are subjected to. When the water pressure changes, the resistance value of the sensitive component of the pressure transmitter will change accordingly, which will cause a change in the output signal, thus achieving monitoring of the water pressure.

  2、 Classification of pressure transmitters for pure water machines

  Pure water machine pressure transmitters can be classified into the following categories according to different classification standards:

  1. Classified by measurement principle:

  Piezoresistive pressure transmitter Ceramic pressure transmitter Diffuse silicon pressure transmitter 2 Classified by output signal:

  4-20mA output 0-5V output RS485 output 3 Classified by installation method:

  Threaded connection card sleeve connection flange connection III. Selection of pressure transmitter for pure water machine

  Choosing the appropriate pressure transmitter is crucial for ensuring the normal operation of the pure water machine. When making a choice, the following factors need to be considered:

  1. Measurement range: The appropriate measurement range should be selected based on the working pressure of the pure water machine to avoid overload or inaccurate measurement.

  2. Accuracy level: The higher the accuracy level, the more accurate the measurement results. The appropriate accuracy level should be selected based on actual needs.

  3. Output signal: The appropriate output signal type should be selected according to the interface requirements of the pure water machine control system.

  4. Installation method: The appropriate installation method should be selected based on the installation space and pipeline size.

  5. Working environment: The appropriate protection level and temperature range should be selected according to the working environment of the pure water machine.

  4、 Installation and maintenance of pressure transmitter for pure water machine

  1. Installation:

  Before installation, carefully read the product manual and understand the installation precautions. During installation, the pipeline should be kept clean to prevent impurities from entering the interior of the pressure transmitter. After installation, debugging should be carried out to ensure that the pressure transmitter is working properly. 2. Maintenance:

  Regularly check whether the appearance of the pressure transmitter is intact and whether the wiring is secure. Regularly calibrate pressure transmitters to ensure measurement accuracy. Avoid the pressure transmitter from being affected by shock, vibration, and corrosive substances. 5、 Application of pressure transmitter in pure water machine

  The pressure transmitter of a pure water machine has applications in the following areas:

  Monitor the pressure before and after the RO membrane to determine if the RO membrane is clogged. Control the start and stop of the booster pump to ensure the working pressure of the RO membrane. Monitor the pressure of the waterway system to prevent water leakage or pipe bursting. Provide water pressure data for water quality analysis and fault diagnosis. 6、 Summary

  As an important component of a pure water machine, the pressure transmitter plays a crucial role in ensuring the normal operation of the equipment and water quality safety. Choosing the appropriate pressure transmitter and installing and maintaining it correctly can effectively extend its service life and improve the reliability of the pure water machine. I believe that with the continuous advancement of technology, pressure transmitters for pure water machines will be more widely used in the future.
