Working Principle

The HTL20 vibrating fork level detectors is based on the design principle of detecting the change of vibration frequency when the tuning fork body is immersed in the medium. That is, when the fork is in contact with the measured liquid, the resonant frequency of the fork is significantly reduced, and the change of vibration frequency is directly reflected in the output signal of the piezoelectric detection device. The detection circuit determines the change of the required rate and outputs a switching signal.

HTL20 vibrating fork level detectors is an economical limit control switch specially designed for liquid limit measurement. The overall structure of the product is small and lightweight, the total length of the product is 160.5mm, the maximum diameter is 31.5mm, and the length of the tuning fork is only 38mm. This product is not only suitable for containers, tanks, tank and foam, bubble, viscous liquid and vibration interference level limit measurement, but also suitable for small containers and small space around the tank. Also based on the design principle of detecting the change of vibration frequency when the fork is immersed in the medium, the product can measure the density of the medium as low as 0.7g/cm³.

Application Scope

HTL20 vibrating fork level detectors is specially used for measuring the level limit of containers, tanks and various pipelines, widely used in water conservancy, chemical, environmental protection, food, medicine and other industries.
