This non-contact type microwave level switch is suitable for detecting dust, coal, gravels, granules etc.

• • Detection is not easily affected by contamination, adhesion, and scale on the detection surface.
• • Reduction in size and weight has been realized by adopting new model of 24 GHz transmitter and receiver.
• • Paper and dust, which are difficult to detect through other methods, can be surely detected.
• • Remote amplifier model is available for the tank with vibration.

When microwaves between the transmitter and receiver is blocked by material, the microwaves are reflected and absorbed. Then the receiver cannot receive microwaves and it outputs contact.
