The basic maintenance knowledge of the input type liquid level transmitter

It is a pressure sensor that measures liquid level. According to the principle of measuring the liquid static pressure proportional to the height of the liquid, the static pressure is converted into an electrical signal by an isolated diffusion silicon sensitive element or a ceramic capacitive pressure sensitive sensor, and then converted into a standard electrical signal through temperature compensation and linear correction. It is suitable for liquid level measurement of various media in petrochemical, metallurgical, electric power, pharmaceutical and other industries.

The input type liquid level transmitter directly inputs the measured medium. It is very convenient to install and use. It has the advantages of good stability, high precision and long service life. It can measure water, oil or paste-like media with high viscosity. It is not affected by blistering, deposition and electrical characteristics of the measured medium. In order to make the input type liquid level transmitter can accurately measure, the maintenance of the equipment should be paid attention to in the daily use process. This article introduces some common sense of the maintenance of the input type liquid level transmitter.

1. Make a record of the operation of the instrument, especially the failure time and phenomenon, for maintenance and query;

2. Be careful not to damage the appearance of the instrument. Especially probes and buttons; it is strictly forbidden to damage the connecting cable mechanically, and stop using it immediately after damage. Especially do not shut down at will during work, develop a good habit, and shut down after various operations are completed;

3. After daily use, turn off the power of the host;

4. Do not disassemble the packaging and carry the instrument within 10 minutes after shutdown; If the instrument is not used for a long time, unplug the power supply plug of the power grid; put the probes, buttons and other parts in the accessory box.
