Single Point Level Sensor
General
The MWS-CTX/CRX-1 type microwave sensor is a level switch consisting of a transmitter (MWS-CTX) and a receiver (MWS-CRX) installed face-to-face.
The transmitter emits a low power microwave beam towards the receiver and an output relay is excited when the beam is obstructed.
The sensor has wide application across all areas of industry where highly reliable, non-contact level detection is required. The sensor is generally used for process control by monitoring presence/absence of product, flow/no flow conditions and point level detection in bins and silos. The sensor may also be used as a proximity switch for detection of vehicles such as dump trucks and rail cars.
Features
High penetration
Easily penetrates process buildup on antenna, firebrick, refractory etc., thanks to the high penetrability.
Unaffected by adverse conditions
The sensor is unaffected by surface contaminants, flames, steam, vapor or airborne particles.
Simple beam alignment
Easy initial beam alignment at installlation, due 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 sensor.
Selectable delay function
Either on-delay or off-delay function may be selected.
Selectable hysteresis
The hysteresis of the output relay can be decreased.
Easy adjustment
Only one sensitivity rheostat makes adjustment easier.
Improved antivibration
