1, reflection type

Non-contact Ultrasonic Level Switch to send a high-frequency ultrasonic pulses, when empty the container wall in the high-frequency pulse propagation, the formation of multiple reflection; full tank in most of the ultrasonic sound waves directly into the liquid only a small amount of reflection. Through 'self-learning' key, Level switch was empty material, full of self-learning material state echo curve. Level measurement switch will echo from the learning curve and the curve analysis and comparison of echo to determine the material level state, and gives the state the output.

2, echo type

Level switch in the reflective mode, when the viscous medium container (such as: lubricating grease) production wall, issued by the absorption of ultrasound by media wall, so that reflected wave reduced, and in severe no reflected wave. In this case, requires the use of return-type operation. Echo across the tank wall type to receive the reflected signal, and thus not subject to the impact of wall materials.

Features

As non-contact measuring technology, whole structure used stainless steel, make switch be with

Non-contact with measured medium, very healthy

Suitable for all kinds of containers: metal, ceramics, glass, plastic

Nothing to do with the vessel pressure;

Convenient installation: holder and the container welding or bonding, and through three claw clasp fixtures bit switch
