Basic Oxygen Furnace Sensor MWS-10RF
General
The MWS-10RF Level Sensor uses rotary microwave radar technology, FM-CW (Frequency Modulated Continuous Wave) measurement method and FFT (Fast Fourier Transform) signal processing to provide, accurate, reliable level measurement combined with user friendly, fast response high tech mWave™ Software.
The MWS-10RF is best suited to the measurement of Iron, Steel and other metallic surfaces under high temperature, dense smoke/dust/vapor and other such adverse environmental conditions associated with iron and steel making.
WADECO’s Range Finder for Basic Oxygen Furnace (BOF) Level Measurement was originally developed for NKK (now JFE) in Japan; the Range Finder is now currently used by all the major Japanese steel makers and is quickly making an entrance into the global market.
Specifically designed and built for the steel industry, the MWS-10RF is widely regarded as being the most advanced of its kind in the world. WADECO has supplied this sensor (for a variety of applications) to many iron and steel makers all over the world.
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 a 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.
