Microwave Sensor
MWS-ST/SR-3-24V

MWS-ST/SR-3-24V

The MWS-ST/SR-3-24V type microwave sensor is a level switch consisting of a transmitter (MWS-ST-3-24V) and a receiver (MWS-SR-3-24V) 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.

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 circuits are molded in the enclosure.
  • Enclosure rating IP65 equivalent
