Both eased by any et the following holes must be used evenly torqued to 16Nm (12 用 that the 4as棒 evenly distribute 1)Mechanical interference betwveen the loading mechanism and the frame of the mach ne. In it is usual to use a fat bar or some o her load particular where product builds up or dirt is trapped spreading member between the applicator and the between the load pillar and the model 240 bod weigh platform, table ar live superstructure. The mating section and the substructure, must be rigid otherwise the latter will oscillate and superimpose 2) The transpartation grub scew in the load cap has not been opened or has vibrated back down on the load cell output, depending on the frequency to the closed pasition and amplitude generated. The supporting membet must he flat 3) The sintered bronze breather filters located on the sies of the load cap are blocked with eontami The load should be transported on to the weigh 轴uqh得s: Or in a low temperature platform in such a way that it creates the minimun plication where the filters hawe been blocked by disturbance. If the lod trans verses acr ass the platform, it should, if poss ble, avoid knocking the or the machine is washed down with aggress ice. If the application is in a corrosive atmosphe platform edge (ie. no step). If the load is lowered chemicals. the filters can also corrode and become on to the platform it should be a controlled place blocked. Plastic filters can be fisted for use in ag ance the line of action of the applied load should gressive environments or a specal version of the model 240 with remote beathing be supplied an act as near as possible to create line of the loac request for use in high humidity, low temperature or cell in both horizontal planes to minimize eccen dusty teaty efrects EFFECT OF TEMPERATURE SEALING The preceding response curves feflect a typical The model 240 is Heal for wash doyin cand tons in ambient temperatare of 20oC, Variations in temperature will alect the viscosty o! the damping the food industry and other demanding environ ments Iuid and consequently the settling time of the load cell a dual combination of a wash down shroud and d aphragm is designed to prevent the ingress of water allowing the load cell to breathe, in order to INSTRUMENTATION overcome variations in barometric pressure The load cell is essentally a strain gauge device of Wheatstone Bridge configuration having input/ Protection is designed to pass a 50 day humidity output signals in milli-volts, Nammaly. standarc load. cell weighing equipment instruments will cycle at 95%R H. and the unit is sealed to IP66 (BS 5490 IEC 529)Cert No 2039 match satisfaconly. but note that the load cell output is offset dependant upan platform ar cotainer PACKAGING, TRANSPORT AND STORAGE weight. The cable should be clamped in position The load cell is packed in a cardboard housing for and should not be contimuously flexing d spatch and should be stored i its original Note, the model 240 is supplied in six wire packaging if pessible. It is essential to store the configuration and where possible this should be load cell upright with the transpartation screw tight lly utilized (see installation sheet), Storage temperatures shouk not exceed-15C to +45C, Never carry the model 240 by the cable Model 240 Damped Load Cells GRADE UNITS ated Capacitive 23.5F7.10.15.2015.71020.30 30.50 Rated Opul 20±10% tal Error 0050 0025 D.020 土% I Applied LA3d eR也 rn afer30rins 0075 0.15 ±% Applied Le NA D0010 6 of Applied LoadI Temperature Effect: On Zero .
