Microwave Sensor
MWS-24TX/RX

MWS-24TX/RX

The MWS-24TX/RX type microwave sensor is a Level Switch which consists of a transmitter (MWS-24TX) and a receiver (MWS-24RX), installed face to face. The transmitter unit transmits a microwave beam which is received at the receiver unit. An output relay is released 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 environments
    The sensor is unaffected by surface contaminants, flames, steam, vapor or airborne particles.
  • Simple beam alignment
    Easy initial beam alignment at installation, 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
