The MWS-20RF-CH Range Finder is the first sensor to ever be developed specifically for measuring the level of coal in the coke oven.
It consists of an antenna and controller,connected via coaxial cable - the antenna and controller are installed separately on the charging car.
Microwave are unaffected by temperature,flames,vapor,airborne particles or dirt.
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.
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).
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).
Portable(6 kg controller,4 kg antenna).
Easy installation.
