Single Point Level Sensor
General
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.
The sensor has many applications across all areas of industries where highly reliable, non-contact level detection is required. The sensor is generally used for process control by monitoring the presence/absence of a product, flow/no flow conditions, and point level detection in chutes, 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 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.
Lightweight, compact & easy to install
The sensor weighs less than 1kg and is housed in a compact aluminum diecast enclosure. Built-in amplifiers allow for no interconnection between the transmitter and receiver.
Improved anti-vibration
All curcuits are molded in the enclosure.
Enclosure rating IP65 equivalent
