One bridge signal is fed to \u003cstrong\u003etwo galvanically isolated 4 … 20 mA current outputs\u003c\/strong\u003e so that a safety controller can check both channels against each other. A \u003cstrong\u003e24 VDC test input\u003c\/strong\u003e raises channel B by 1 mA.\u003c\/p\u003e\n\u003cp\u003eThe rated loads are \u003cstrong\u003e500, 1000, 1500 and 3000 kg\u003c\/strong\u003e (5 to 30 kN), for compression, tension or tension and compression. The nominal working range is \u003cstrong\u003e8 … 16 mA\u003c\/strong\u003e within the valid range of 4 … 20 mA; zero is at 8 mA (compression or tension) or 12 mA (tension and compression), the load resistance max. 500 Ω. Linearity and hysteresis of the measuring cell are \u003cstrong\u003e0.5 %\u003c\/strong\u003e of range each, repeatability is \u003cstrong\u003e0.05 %\u003c\/strong\u003e, creep and temperature drift are 0.05 % each (per 10 min and per 10 K). The safe overload is \u003cstrong\u003e150 %\u003c\/strong\u003e, the breaking load \u003cstrong\u003e200 %\u003c\/strong\u003e of range.\u003c\/p\u003e\n\u003cp\u003eThe cell is supplied with \u003cstrong\u003e24 VDC ±10 %\u003c\/strong\u003e at max. 100 mA. It is connected via two M12x1 connectors: 4-pin for output A and test pulse, 8-pin for output B and supply. Both connection cables are included in delivery. EMC according to EN 61326-1, EN 61326-2-1 and EN 61326-3-1.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImportant regarding the safety rating:\u003c\/strong\u003e The TÜV test certificate SIL3 \/ PL e covers the \u003cstrong\u003eelectronics\u003c\/strong\u003e, not the force measuring cell – according to the manufacturer, the integrated sensor was not part of the tests. Both analogue signals must be evaluated by a controller approved for SIL3 \/ PL e; it is not included in delivery. A measuring accuracy of the amplifier is not documented.\u003c\/p\u003e\n\u003cp\u003eThe material is \u003cstrong\u003estainless steel\u003c\/strong\u003e or nickel-plated tool steel, the protection class is \u003cstrong\u003eIP54\u003c\/strong\u003e, and the electronics are fully potted. Mounting is via \u003cstrong\u003erod ends\u003c\/strong\u003e, which are included in delivery, or without rod ends using the threaded bores of the cell. The weight is approx. \u003cstrong\u003e343 g\u003c\/strong\u003e (500 and 1000 kg) or \u003cstrong\u003e423 g\u003c\/strong\u003e (1500 and 3000 kg), each without rod end and without covers. Operating temperature -25 … +60 °C, storage temperature -25 … +85 °C, humidity up to 96 % RH without condensation.\u003c\/p\u003e\n\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBuilt-in safety measuring amplifier SIL3 \/ PL e, category 3\u003c\/li\u003e\n\u003cli\u003eTwo galvanically isolated 4 … 20 mA outputs\u003c\/li\u003e\n\u003cli\u003e24 VDC test input for diagnostics\u003c\/li\u003e\n\u003cli\u003eRated loads 500, 1000, 1500 and 3000 kg (5 to 30 kN)\u003c\/li\u003e\n\u003cli\u003eStainless steel, potted electronics, protection class IP54\u003c\/li\u003e\n\u003cli\u003eBoth M12 connection cables and rod ends included\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"500 kg","offer_id":57472528220486,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true},{"title":"1 t","offer_id":57472528253254,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true},{"title":"1.5 t","offer_id":57472528286022,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true},{"title":"3 t","offer_id":57472528318790,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true},{"title":"5 kN","offer_id":57472528351558,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true},{"title":"10 kN","offer_id":57472528384326,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true},{"title":"15 kN","offer_id":57472528417094,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true},{"title":"30 kN","offer_id":57472528449862,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/LZMB_produkt.webp?v=1790601549","url":"https:\/\/octogon.org\/en\/products\/lzmb-universal-force-measuring-cell-sil3-pl-e","provider":"octogon GmbH","version":"1.0","type":"link"}
