Remarks Famille capteurs SK SK Load cells family A Mechanical Schema electrique SK / SK Electrical Diagram B Electrical Cable: - The standard cable length has to be approximately 5 meters. - The load cell is provided with a 6-wire system (= Remote-sensing ). The cable length is not limited. - The cable should be a shielded cable, the shield can be connected (additional marking TR ) or not connected to the load cell. 1.2 Essential characteristics Minimum dead load : 0 kg Safe overload : 150 % of E max Rated Output : 2 mv/v Input impedance : 385 Ω ± 20 Ω or 1100 Ω ± 50 Ω Output impedance : 350 Ω ± 5 Ω or 1000 Ω ± 10 Ω Recommended excitation : 10 V DC/AC Excitation maximum : 15 V DC/AC Transducer material : Stainless Steel Atmospheric protection : Hermetically sealed 1.3 Essential shapes The load cell is built according to the drawing: - Famille capteurs SK / SK Load cells family, drawing number The data plate is secured against removal by sealing or will be destroyed when removed. The data plate mentions at least the information and markings as described in the OIML R60 document. In the countries where it is mandatory the load cell should bear this test certificate number: TC6482. Securing: The connecting cable of the load cell or the junction box is provided with possibility to seal.
