4 Channel Deluxe Type Microwave Sensor
MWS-ST/SR-2

MWS-ST/SR-2

The MWS-ST/SR-2 type microwave sensor is a level switch which consists of a transmitter (MWS-ST-2) and a receiver (MWS-SR-2), installed face to face. It comes with four channels to allow for installation of multiple sets in close proximity.
The transmitter transmits microwaves toward the receiver and an output relay in the receiver is released when the beam is obstructed.
Harsh environments may result in the buildup of contaminants on the sensing surfaces, however, the sensor easily penetrates this buildup, thanks to the high penetrability of microwaves.

Features

  • 100m Range with heterodyne detection
    Approx. 100m range with a ø27mm antenna, thanks to the Heterodyne detection method.
  • High penetration
    Easily penetrates process buildup on antenna, firebrick, refractory etc., thanks to the increased operating range.
  • Unaffected by adverse environments
    The sensor is unaffected by surface contaminants, flames, steam, vapor or airborne particles.
  • Selectable detection mode
    Either broken beam (BLOCK) or unbroken beam (UNBLOCK) detection method may be selected.
  • On delay time rheostat
    On delay time, adjustable 0.1~10secs., prevents instantaneous detection of falling material whilst filling.
  • 15 LED indicator bank
    A 15 LED indicator array displays the received power level and the sensitivity-set-point, allowing for visual sensitivity adjustment and maintenance.
  • No set-to-set interference
    Four channels are available, selectable by rotary switch, eliminating set-to-set interference.
  • Inspection window (optional)
    The received power level and the sensitivity-set-point are easily seen, without removing the controller cover.
  • High speed static relay (optional)
    5msec response time static relay.
