{"product_id":"lwma-gasflaschenwaage","title":"LWMA Gas Cylinder Scale, 250 and 500 kg","description":"\u003cp\u003eThe \u003cstrong\u003eLWMA\u003c\/strong\u003e is a gas cylinder scale for continuous operation: the liquefied gas cylinder stays on the scale permanently, with display, limit values and overload protection built in. It is suitable for weight and level measurement in the industrial sector, for example to see in good time when a cylinder needs to be changed.\u003c\/p\u003e\n\u003cp\u003eThe scale measures the weight on a round weighing platform and outputs it as \u003cstrong\u003e4 … 20 mA with superimposed HART signal\u003c\/strong\u003e on the 2-wire current loop, supplied with \u003cstrong\u003e12 … 40 VDC\u003c\/strong\u003e from the loop. Two electronic \u003cstrong\u003ePNP limit value contacts\u003c\/strong\u003e (30 VDC, 200 mA) switch with freely adjustable switching point, hysteresis and delay, galvanically isolated from the measuring amplifier. The 4-digit red \u003cstrong\u003eLED display\u003c\/strong\u003e shows the reading right at the scale and stores minimum and maximum. Settings are made with three keys or by software via HART. The measuring amplifier works with \u003cstrong\u003e16 bit\u003c\/strong\u003e and \u003cstrong\u003e10 measurements\/s\u003c\/strong\u003e, linearises over up to 10 points and has a total error of \u003cstrong\u003e0.3 % of range\u003c\/strong\u003e, the load cell 0.02 % of range.\u003c\/p\u003e\n\u003cp\u003eAvailable with \u003cstrong\u003e250 kg\u003c\/strong\u003e (platform Ø 245 mm, height approx. 80 mm, approx. 7 kg) and \u003cstrong\u003e500 kg\u003c\/strong\u003e (platform Ø 410 mm, height approx. 95 mm, approx. 19 kg). Weighing and base plate are made of zinc-plated steel, the overload protection is adjustable via three locking rings, and the load cell withstands \u003cstrong\u003e120 %\u003c\/strong\u003e overload and \u003cstrong\u003e150 %\u003c\/strong\u003e breaking load. Connection is via \u003cstrong\u003e2 × M12x1, 5-pin\u003c\/strong\u003e, which also allows several scales to be connected together, with a separate 4 … 20 mA signal per scale and the limit value contacts wired in parallel.
