Microwave Range Finder MICRO-RANGER®
MWS-10RF

The MWS-10RF Microwave Range Finder consists of an antenna connected to a controller by circular waveguide tubing. The heat resistant antenna is installed in the high temperature zone, while the controller is located in a room temperature area allowing the sensor to make accurate measurements in high temperature areas without special cooling.

Features

  • Unaffected by adverse conditions
    The antenna, which is the sensing head, can be installed in the high temperature zone without the need of additional cooling devices.
    The antenna and controller are easily connected by circular waveguide tubing, using special 90° turns and straight pieces.
    Microwaves are unaffected by temperature, flames, vapour, airborne particles or dirt.
  • High accuracy and reliability
    Error less than 10mm.
    False measurements caused by double-reflected waves are eliminated through the use of rotary microwaves.
    The accuracy of the measured range is not affected by fluctuating temperatures nor does it deteriorate over extended periods.
    Utilizes filters which eliminate spurious signals.
  • The operational state is shown on your personal computer
    It displays an FFT spectrum, the received signal and various preset values.
    The received signal, FFT spectrum and the trend measurement are continuously displayed. This displayed data can be recorded and reviewed in real or accelerated time.
    Use of the recording and reviewing capabilities allows the system parameters to be optimised offline.
    The display indicates and outputs the internal temperature and any abnormal conditions. (i.e. a lowering of received signal power, rising temperature in the controller, software version mismatch and communication failures.)
  • Convenient built in functions
    A reference point and the required range can be preset.
    The length of waveguide is easily subtracted from the overall distance measured.
    Compatible for use with a personal computer.
    Automatic power supply 90~240V, 50/60Hz.
    Communicates with computer by RS-232C.
    4-20mA, analogue output.
    RS-422 digital output and input terminals.
  • Lightweight and compact
    Portable (5.7kg controller only)
    Easy installation.
  • High versatility
    Both hardware and software can be modified to suit your requirements.
