Hydrotechnik pressure sensor is a commonly used sensor in industrial production. It has the characteristics of small size, light weight, and easy use. Widely used in various industrial automation control environments, including water conservancy and hydropower, railway transportation, intelligent buildings, production automation control, aerospace, military industry, petrochemicals, oil wells, electricity, ships, machine tools, pipelines and many other industries.

When using this sensor, it is necessary to regularly check the zero point and calibrate it regularly; Regular discharge, coagulation, and emptying; Regularly blow and clean the pressure pipes that are prone to clogging media, and regularly add isolation fluid. It is very important to keep the installation holes clean and prevent the blockage of molten materials for the normal operation of the equipment. Before cleaning the extruder, all pressure sensors should be removed from the cylinder to avoid damage. After removing the sensor, molten material may flow into the mounting hole and harden. If these residual molten materials are not removed, the top of the sensor may be damaged when reinstalling it. The cleaning kit can remove these molten residues. However, repeating the cleaning process may deepen the damage caused to the sensor by the mounting holes. If this situation occurs, measures should be taken to raise the position of the sensor in the installation hole.

The quality of the hydrotechnik pressure sensor must be checked before use. The pressure sensor is accurate and sensitive, with indication error and static pressure error meeting the requirements, and the zero position is correct; The instrument components are intact, without severe rust or damage, the nameplate is clear and correct, the fasteners are not loose, the joints are in good contact, and the terminal wiring is firm; The technical documentation is complete, accurate, and meets management requirements.

The piezoelectric materials mainly used in this sensor include quartz, potassium sodium tartrate, and dihydrogen phosphate. Quartz (silicon dioxide) is a natural crystal in which the piezoelectric effect has been discovered. Within a certain temperature range, piezoelectric properties always exist, but when the temperature exceeds the Curie point, the piezoelectric properties * disappear.
