kaidi KFLS10-EH Normal Temperature Tuning Fork Level Switch

Product Overview

kaidi KFLS10-EH room temperature type tuning fork level switch is a kind of solid material level switch specialised in measuring powder and fine particles, it can measure fine sand, fine chemicals, flour, salt and other materials, the lowest density is up to 0.008g/cm³, which is especially suitable for ultra-low density material level measurement, it has a wide range of adaptability and very high reliability.

Working Principle

The probe of the tuning fork level switch is based on the tuning fork design, and adopts piezoelectric devices to realise the vibration drive and detection of the fork body. When not in contact with the material, the tuning fork vibrates freely at the resonant frequency. When the tuning fork is in contact with the measured material, the vibration amplitude of the tuning fork decreases significantly, and the amplitude of the output signal of the piezoelectric detecting device decreases accordingly, and the signal change is detected and analysed by the intelligent circuit and outputs a switching signal. The product through a reasonable increase in the area of the fork body, and the fork body after precision tuning, the sensitivity can be greatly improved, can measure the density of materials as low as 0.008g/cm³.

Product Installation

Installation Precautions:

1. When installed horizontally, the material level switch should be tilted 20° to prevent the phenomenon of hanging material. In order to reduce the direct impact of the material on the probe, you can install a protective baffle above the vibrating body, and the length of the baffle should be greater than the length of the horizontal installation of the probe. For general materials, the cross-section shape of the protective baffle is inverted V-shaped; for rough and dense materials, the cross-section shape of the protective baffle adopts positive V-shaped, in order to reduce the wear and tear of the material on the protective baffle. As shown in Figure I.

2. The material level switch should be avoided to be installed in the inlet to prevent damage or false operation caused by the impact of materials, and the fork face and the direction of media flow should be consistent.
