Tuning fork level meter Description:
HN-YC series tuning fork level sender is in our original series H-YC tuning fork Level sender on the basis of major technological improvements produced by the new generation of products. With advanced integrated circuit, a good product mix and manufacturing standards. Its performance to achieve the advanced level of similar foreign products.
HN-YC series tuning fork level meter
Working principle and structure
Level sensor portion of this product is based on the work of the tuning fork principle. Tuning fork is driven by the weak energy will be able to cause resonance elastic body, when it is subject to material damping effect drastically reduced amplitude and frequency, and phase change significantly, by an electronic circuit with a tuning fork vibration excitation piezoelectric ceramic element and the output switching signal. The working principle block diagram shown in Figure.

Purpose and Scope:
HN-YC series of products for various openings or the inner pressure vessel level detection, alarm or digital control, with sound and light alarm device or connected to a computer monitoring system, and I can also plant the production of UZC controller fit, UZC or use within the non-contact switch relay (SSR) direct control of pumps, valves, motors and other equipment, material level automatic control. Teflon-treated by anti-corrosion product release, contact material portion having equivalent PTFE corrosion resistance and good anti-adhesion properties of materials can be used in a certain corrosive and viscous material level measurement.
Long products applicable to the vessel wall is very thick, or the top of the container for mounting vertically downward.
Separate type of material used for the measured temperature exceeds the specified range (-20 ~ 80 ℃) level detection, such products fork and partial separation of the circuit box. To ensure that the circuit portion under normal ambient temperatures, the separation distance should be less than 20m.
Product is suitable for high-temperature material temperature level detection in the range of -20 ~ 200 ℃.
Separate product is suitable for longer and longer applicable separate common level detection.
Long product is suitable for high-temperature and high-temperature longer applicable common level detection.
