The MWS-ST/SR type microwave sensor is a level switch consisting of a transmitter (MWS-ST) and a receiver (MWS-SR) installed face-to-face.
The transmitter emits a continuous, low power microwave beam towards the receiver and an output relay is released when the beam is obstructed.
High penetration
Easily penetrates process buildup on antenna, firebrick, refractory etc., thanks to the high penetrability of microwaves.
Unaffected by adverse environments
The sensor is unaffected by surface contaminants, flames, steam, vapor or airborne particles.
Simple beam alignment
Easily initial beam alignment at installation, thanks to the wide beam angle.
Sensitivity margin indicators
The sensitivity margins are indicated on the receiver by LEDs allowing for easy visual adjustment and maintenance of the sensors.
