WEIGHT INDICATORS

THE WB-900 AND WB-902 FOR VERSATILEWEIGHING TASKSWB-900 and WB-902 weight indicators are designed foraccurate static weighing to meet the needs of industry,transport and commerce. They are practical, dependabletools wherever quantities of raw materials or finishedproducts have to be measured and a high degree ofaccuracy is required.Typical applications include:- scales for reception and dispatch of goods- scales for monitoring raw material stocks- scales for paper reels- overhead track scales for laundries or slaughterhouses- vehicle scales- high precision tank and silo weighing- freight goods scales (freight depots, postal depots)

Thanks to the robust construction and high protection classof the enclosures the WB weight indicators can be usedeven in extremely hostile conditions — whether due tohumidity or electrical interference. Mobile phones can be

used in the vicinity of the scales without disturbing theweighing process. With the 24 VDC supply option, theindicators can be used where a normal mains supply is notavailable.

OProviding versatile interfaces, the WB weight indicatorscan be connected to various logic units and computers.Several indicators can be linked up to a computer via acommon RS 485 bus. The functions of the indicator can becontrolled through a serial interface, thus allowing unman-ned operation. In addition, four control inputs and outputscan be specified to control weighing operations for indi-vidual applications.

All options are available as modules so that both hardwareand software are easily modifiable.

The versatile built-in testing and monitoring functions guar-antee that weighing results will be reliable in all conditions.

CALIBRATION BY KEYBOARDThe WB weight indicators have easy-to-use keyboard cali-bration. All operating parameters are stored in the memorycircuit and protected by a password. Calibration is facilitated

by automatic corner adjustment and extended indicationdevice which gives a ten times more accurate reading. Thereis thus significantly less need to handle the weights.

HIGH PRECISIONThe WB-900 and WB-902 weight indicators have EC typeapproval and extremely high precision — 10 000 e. Internalresolution is up to 2 000 000 using 1 s measuring time.

ALL FUNCTIONS ON KEYBOARDThe function keys are clear and easy to use.

THE WB-902 HAS HIGHER DISPLAY ANDMEMORY CAPACITYThe versatile WB-902 is especially suitable for mannedpiece weighing in industrial environments. The indicatoris simple to use with clear, numerical keyboard andeasy-to-read functions on the LCD MENU display.

For easier, faster weighing, product codes and corre-sponding tareweights can be programmed into the mem-ory. Tareweights can be preset either by keyboard or byweighing.

The totalising counters calculate total quantities weighedand display them if required. The counters can also bepreset by keyboard and weighing data are collected eitherby adding or subtracting.

Consecutive number and time and date memories enablesubsequent tracing of the weight and weighing time of aspecific product. This data can easily be recorded byconnecting a printer to the WB-902 or transmitting thedata to a computer memory.
