Description

Technical Field

[0001] The utility model relates to the technical field of digital pressure gauges, in particular to a high-precision detection and control device for digital pressure gauges. Background Art

[0002] Digital pressure gauge is an online measuring instrument. It has the advantages of small size, safe and reliable performance, and clear display. It can accurately measure flow, liquid level, gauge pressure, absolute pressure, vacuum and specific gravity. It is directly connected to secondary instruments and computer control systems to realize automatic detection and control of the production process. It can be widely used in various industrial fields for gas and liquid pressure detection.

[0003] After searching, the application with patent number CN202110438630.7 discloses a high-precision detection control method and system for a digital pressure gauge, including the following steps: cleaning the hydraulic sensor, obtaining the ambient temperature value and liquid pressure value in the pipeline to be tested, comparing the obtained liquid pressure value with the preset conventional pressure value range, and making an alarm response if the liquid pressure value is outside the conventional pressure value range, and compensating the liquid pressure value according to the ambient temperature value output pressure compensation value. At the same time, according to the statistical usage time, the liquid pressure value is aging compensated to form a corrected pressure value, and displayed to the personnel. By setting up a temperature compensation database, the influence of temperature on the detection accuracy of the digital pressure gauge can be reduced; by cleaning the hydraulic sensor, impurities can be prevented from adhering to the hydraulic sensor and affecting the detection accuracy of the hydraulic sensor;

[0004] The above application document realizes high-precision detection of hydraulic sensors by means of aging compensation, wherein the first and relatively important step is to clean the hydraulic sensor in the digital pressure gauge, wherein the dirt in the hydraulic sensor is mainly scale. The above application document cleans the scale on the hydraulic sensor by ultrasonic cleaning, but the sensor needs to be disassembled and then placed in an ultrasonic cleaning machine, which is cumbersome to operate and has low work efficiency.

[0026] Among them, the high-precision detection and control device of the digital pressure gauge can be mounted on the outer wall of the hydraulic sensor 1 through the setting of the outer sleeve 2, and use the power socket 4 to drive the electromagnetic pulse generator 3 to work, and cooperate with the electronic module therein to make the electromagnetic coil 5 send a pulse current signal. The variable magnetic field generated by the electromagnetic pulse generator 3 will cause magnetic displacement vibration at the atomic level on the heating surface, resulting in the stratification of the scale layer, and then the scale will peel off, break, and partially turn into creamy hard salt, and dissolve in the magnetized water in the hydraulic sensor, and then be discharged along the water pipe, so that the scale therein can be cleaned without disassembling the hydraulic sensor 1. The operation is simple and the work efficiency is high, which solves the problem that the existing device needs to disassemble the hydraulic sensor 1 separately and the subsequent cleaning work efficiency is low.

[0027] Embodiment 2:

When the scale inside it needs to be cleaned, the power socket 4 is turned on to energize the electromagnetic pulse generator 3. At this time, the electronic module therein cooperates to make the electromagnetic coil 5 emit a pulse current signal. The variable magnetic field generated by the electromagnetic pulse generator 3 will cause magnetic displacement vibration at the atomic level on the heating surface, resulting in the stratification of the scale layer, and then the scale will peel off, break, and partially become creamy hard salt, and dissolve in the magnetized water in the hydraulic sensor, and then be discharged along the water pipe, so that the hydraulic sensor 1 can be cleaned without disassembling it.
