Problems solved by technology

Due to the harsh actual environment of industrial sites and the complex and changeable actual composition of materials, the actual measurement accuracy of radio frequency admittance and capacitive level gauges is very poor. In specific industrial sites, radio frequency admittance and capacitive level gauges have lost market
Although various improvements have been made in the field of radio frequency admittance and capacitance level gauges at present, the false alarms or measurement errors caused by the accumulation of materials in the actual industrial site The problem is still not effectively resolved

Embodiment approach 1

[0019] This embodiment provides a mechanical action-assisted verification, anti-hanging static mode material level gauge and its method for measuring material level. The static mode material level gauge is mainly composed of electrode detection components, arithmetic processors, signal output components, mechanical action component and three electrodes, wherein the electrode detection component, mechanical action component, and signal output component are all connected to the arithmetic processor, the three electrodes are connected to the electrode detection component, and the three electrodes are separated by insulating components, and the mechanical action The parts are installed between the three electrodes, at this time the mechanical action parts can choose to use rotating parts, swinging parts, vibrating parts or sliding parts, such as figure 1 (The mechanical action part is a rotating blade), and the mechanical action part can also be directly arranged near the electrod...

Embodiment approach 2

[0032] This embodiment is a further improvement of Embodiment 1. The main improvement is that in Embodiment 1, the start-up conditions of the mechanical action parts are pre-designed inside the arithmetic processor. When the physical quantity information before start-up meets the above-mentioned start-up conditions, The mechanical action parts will start. If the above starting conditions are not met after a period of time after starting, the mechanical action parts will stop running. Due to the large error in the electrode detection itself, the start of the mechanical action parts in Embodiment 1 is not practical. In the application, it may cause the problem that the material on the electrode cannot be removed in time; and in this embodiment, it is possible to directly set the specific time for the mechanical action part to start, how long to stop after starting, and how long to restart after the interval. To ensure that the material on the electrode can be removed in time to e...

Embodiment approach 3

[0035] This embodiment is a further improvement of Embodiment 1. The main improvement is that in Embodiment 1, if there is a material whose material level rises slowly and has a large temperature difference with the measurement environment, the heat radiation of the material itself will affect the electrode. The accuracy of the detection makes the reliability of the physical quantity information before starting detected by the electrode greatly reduced, and the error of the measurement result is increased. Early start; and in this embodiment, at least two temperature measuring components are also included in the level gauge, and each temperature measuring component is respectively arranged at different positions to be measured in the measurement space for collecting temperature data at corresponding positions, And send the collected temperature data to the computing processor, and the computing processor will compare the physical quantity information and temperature data before...

Abstract

The invention relates to the field of charge level indicators, and discloses an attachment-preventing static mode charge level indicator assisting validation by mechanical action and a measuring method of the charge level indicator. Electrodes and an operation processor are all electrically connected with an electrode detection part; a mechanical action part and a signal output part are respectively in signal connection with the operation processor; the mechanical action part is mechanically connected with the electrodes or is close to the electrodes; when the charge level indicator is used, the electrodes and the mechanical action part are arranged at a position to be measured in a measuring space. According to the charge level indicator, the mechanical action part is started under a starting condition, and during the operation of the mechanical action part, the operation power thereof clears away attached materials on and among the electrodes mechanically connected with the mechanical action part, or clears away attached materials on and among the electrodes close to the mechanical action part by means of fluctuation of ambient air and / or materials, caused by the operation of the mechanical action part, so as to assist the operation processor to judge and output accurate and reliable charge level information, and achieve an effect of preventing attachment. The measurement accuracy and reliability of the static mode charge level indicator are remarkably improved.

Description

technical field [0001] The invention relates to the field of material level gauges, in particular to a mechanical action auxiliary verification, anti-hanging static mode material level gauge and a measuring method thereof. Background technique [0002] The current contact level gauge (level switch) is widely used in the industrial field, with various principles and varieties. Among them, capacitive level gauges, radio frequency admittance level gauges, tuning fork level gauges, resistance rotary level gauges, floating ball level gauges, hammer level gauges and other contact level gauges occupy the vast majority of the market. part of the market share. However, these current contact level gauges have exposed their own product defects in the actual use of industrial sites, and even lead to their inability to be used reliably for a long time in actual industrial sites. It has brought safety hazards and difficulties to industrial production. [0003] Capacitive level gauges a...
