Microwave Sensor Applications

Coke Oven Level Sensor
MWS-24RF-CH

MWS-24RF-CH

UNAFFECTED BY HEAT, FLAMES OR VAPOR
The MWS-24RF-CH type Range Finder was developed, first in the world, specifically for measuring the coal level in the coke oven. The sensor employs FMCW measurement method and FFT signal processing and consists of a controller and an antenna. The sensor is installed on the charging car and the controller and the antenna are connected by a coaxial cable.

Features

  • Unaffected by adverse conditions
    Microwave are unaffected by temperature,flames,vapor,airborne particles or dirt.
  • High accuracy and reliability
    Stable measurement even when the surface of the coal is sloped.
    Employs the rotary microwave technique in spite of the lage frequency sweep:false measurements caused by double-reflected waves are eliminated through the use of rotary microwaves.
    Due to the high S/N ratio, the sensor provides stable measurement even when the reflection from the target [coal] is very weak.
    ±20 mm accuracy.
    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 continually 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 optimized off-line.
    The display indicates and the controller outputs the internal temperature and any abnormal conditions (i.e. a lowering of received signal power, rising temperature in the controller and communication failures).
  • Convenient built-in functions
    A reference point and the required range are easily preset.
    Compatible for use with a personal computer.
    Automatic power supply 90 240V, 50/60Hz.
    Communicates with a Personal Computer by RS-232C.
    4-20mA, analogue output.
    RS-422 digital output terminals (distance, receiving power level, temperature and alarm).
  • Lightweight and compact
    Portable(6 kg controller,4 kg antenna).
    Easy installation.
