FMCW Radar Continuous Level Sensor

Features

ULTRA HIGH-RESPONSE TYPE

Tens of msec. Update time

Suitable for measuring the stockline profile in blast furnaces or measuring surfaces which are rapidly fluctuating.

UNAFFECTED BY ADVERSE CONDITIONS

If necessary, the reflector, which is the sensing head, can be installed in the high temperature zone without the need of additional cooling devices.

Furthermore, if necessary, a circular waveguide can be used to distance the controller from the antenna located in the high temperature area.

Milliwaves are unaffected by heat, flames, dust or vapor.

HIGH ACCURACY AND RELIABILITY

The 45 GHz model uses a smaller antenna, creating a sharper beam angle. This makes the Milli-Ranger ideal for installations where space is limited.

Previously difficult measurements with large rest angles are now possible with milliwaves, therefore the Milli-Ranger is suitable for measuring sloped surfaces of anything from powder to lumps of material.

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 the FFT spectrum, the received signal and various preset values.

The received signal, FFT spectrum and the measurement data are continuously displayed. This displayed data can be recorded and reviewed in real or accelerated time.

Use of the recording and reviewing function allows the system parameters to be optimized offline.

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, software version mismatch and communication failures).

CONVENIENT BUILT-IN FUNCTIONS

A reference point and the required range are easily preset. The length of the guidepipe and waveguide, if used, can easily be removed from the overall distance measured.

Compatible for use with a personal computer.

Universal power supply 90-240V, 50/60Hz.

Communicates with a personal computer by RS-232C or RS-422.

RS-422 digital output terminals (outputs distance, receiving power level, temperature and alarm).

4-20mA analogue output.

LIGHTWEIGHT AND COMPACT

Portable (5.7kg controller only). Smallest antenna size yet.

Easy installation.

HIGH VERSATILITY

Both hardware and software can be modified to suit your requirements.
