MWS-24RF

MWS-24RF

The MWS-24RF is an FM-CW Microwave Range Finder which consists of an antenna and a controller. The controller can be separated from high temperature zones by using a guide pipe and coaxial cable.
The heat resistant reflector is installed in the high temperature zone, while the controller is installed in a normal temperature area, allowing the sensor to make accurate measurements in high temperature areas without requiring special cooling.

Features

  • Unaffected by adverse conditions
    The reflector, which is the sensing head, can be installed in the high temperature zone without the need of additional cooling devices.
    A circular waveguide or coaxial cable can be used to distance the controller from the antenna in high the temperature area. This distance can be greatly extended by using a guide pipe and reflector.
    Microwaves are unaffected by temperature, flames, vapour, airborne particles or dirt.
  • High accuracy and reliability
    The 24GHz model uses a smaller antenna, creating a sharper beam angle. This makes the Range Finder ideal for installations where space is limited.
    Previously difficult materials, such as ash, are easier to detect.
    Accuracy ±5mm.
    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.
    The software utilizes filters which eliminate spurious signals.
  • The operational state is shown on your personal computer
    It displays an FFT spectrum, received signal and various preset values.
    The received signal, FFT spectrum and 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 the waveguide or coaxial cable can be 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). Smaller antenna size.
    Easy installation.
  • High versatility
    Both hardware and software can be modified to suit your requirements.
  • Beam angle adjuster (optional)
    Allows the beam angle to be adjusted to hit the desired position.
