Description

Technical Field

[0001] The utility model belongs to the technical field of tuning fork level switches, in particular to a tuning fork level switch which is convenient for fixed installation. Background Art

[0002] A tuning fork level switch is also often referred to as a tuning fork level meter or tuning fork level controller. A tuning fork level switch is a type of level switch that primarily utilizes the principle of tuning fork resonance to measure the level state. This principle involves using a pair of piezoelectric crystals mounted on the base of the tuning fork to vibrate at a specific resonant frequency. When the tuning fork comes into contact with the measured medium, the frequency and amplitude of the tuning fork change. These changes are detected, processed, and converted into a switching signal by an intelligent circuit. The unique fork design and inherent vibration characteristics of the tuning fork level switch ensure the automatic clearing function of the tuning fork and minimize material buildup. Therefore, it is widely used in process level control in industries such as metallurgy, building materials, chemicals, light industry, and grain.

[0003] The tuning fork level switch needs to be installed and fixed during operation in order to work better. The existing installation and fixing methods are generally top-mounted and side-mounted, and the mounting surface is generally a horizontal surface or a vertical surface. When installing and fixing on the top or wall of an inclined cylinder, it is not convenient to fix it directly horizontally or vertically, which affects its installation and fixation. Therefore, there is an urgent need for a tuning fork level switch that is highly adaptable and can be conveniently fixed in different installation positions. Utility Model Content
