Remarks Load cell assembly CSP-M-40-EEx-C Mechanical Outline Dimensions Special CSP-M 10t / 100 t Mechanical Load cell Assy. type CSP Electrical Cable: - The load cell is provided with a 4-wire system; - The cable length has to be approximately 10 meters for capacity of 5 t and 10 t; - The cable length has to be approximately 20 meters for capacity of 25, 40, 60 and 100 t; - The cable should be a shielded cable, the shield is 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 : 450 Ω ± 4.5 Ω Output impedance : 480 Ω ± 4.8 Ω Recommended excitation : 5-20 V DC/AC Excitation maximum : 25 V DC/AC See also drawing Specifications load cell CSP-M-..t-., drawing number HV Essential shapes The load cell is built according to the drawings: - Load cell assembly CSP-M-40-EEx-C, drawing number ; - Outline Dimensions Special CSP-M 10t / 100 t, 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: TC2194. Securing: The connecting cable of the load cell or the junction box is provided with possibility to seal.
