Types of Explosion-proof Tuning Fork Level Switch

Vibrating Fork Level
The high-temperature vibrating fork level is a level control device designed for high-temperature environments. It uses advanced electronic technology, uses piezoelectric ceramic elements as vibration sources, and uses tuning forks to sense the presence or absence of materials or the height of liquid levels.
Limit switch sensor
There are two types of Tuning fork limit switch sensor: flameproof and intrinsically safe (referred to as intrinsically safe). Among them, explosion-proof tuning fork level switches mainly use metal shells to seal electrical components to prevent ignition sources from coming into contact with hazardous gases.


Water tank high and low level float switch
The Water tank high and low level float switch, also known as water level switches or liquid level sensors, as the name suggests, are switches used to control the liquid level. Formally, it is mainly divided into contact type and non-contact type. Commonly used non-contact switches include capacitive level switches, while contact float level switches are the most widely used.
DPDT output tuning fork level switch
The Vibrating fork liquid level switch is a universal tuning fork switch. The tuning fork of theVibrating fork liquid level switch is excited by a piezoelectric crystal to generate vibration. When the tuning fork is immersed in a liquid or solid, the vibration frequency changes. This frequency change is detected by the electronic circuit and outputs a switching value.

Installation Requirements of Compact Tuning Fork Level Switches
Identify the Installation Location: Determine where the tuning fork level switch will be installed. This could be on a tank, silo, or any other container where the level of a substance needs to be monitored.
Prepare the Installation Site: Ensure that the area is clean and free from any obstructions that could interfere with the tuning fork level switch installation or operation of the switch.
Mount the Switch: Place the tuning fork level switch at the desired height. The forks should be positioned horizontally, and the unit should be securely fastened to prevent movement.
Connect the Wiring: Follow the manufacturer's instructions to connect the wiring of the switch to your control system. Ensure all connections are secure.
Test the Switch: Once installed, test the switch to make sure it is functioning correctly. This can usually be done by filling the container to the level at which the switch is set to activate and checking if it does so.
