Page 5: General
Load cell KxxD-(D) General KxxD-(D) is a line of load cells (KOSD-(D), KIMD-(D) and KISD-(D)) with a high degree of protection. They incorporate resistive strain gauges, measuring the shear force or tension. The KxxD-versions have one electrical circuit and the KxxD-D-version two separate electrical circuits. - Page 6 User Manual The load cells can be supplied with connector or cable connection (see also page 6 and 7). 4-pin connector Cable connection KxxD with one 4-pin connector or cable KxxD-D with one 8-pin connector or cable connection ...

Page 8: Intrinsic Safety
User Manual Intrinsic safety All load cells KxxD (-D) can be approved for use in explosive gas or dust area. The last ‘X’ in the type code (see load cell ATEX label) is a number to identify the specific model. They can be ordered either with a cable connector or with an integrated cable. The safety description is labelled on the load cell. -
Page 9: Functional Safety
Load cell KxxD-(D) Functional safety From a safety point of view is the KxxD-(D) load cell an individual safety component connected to an overall safety control unit. Each individual amplifier strain gauge bridge output shall be connected to separate control system input(s) as view in figure below, see also application examples. -
Page 10: Electrical Connection And Supply Voltage
User Manual Load cell connection The load cell single or double strain gauge bridge outputs shall be connected using shielded cable. It shall than be connected to the measuring equipment bridge mV/V input signal channel The bridge power shall be connected to E+ and E- outputs and the measuring equipment signal input shall be connected to the S+ and S- outputs. -

Load cell KxxD-(D) Application examples Load cell KxxD (one strain gauge bridge) and KxxD-D (two strain gauge bridges), used in a non-hazardous area, are shown below. Load cell KxxD-D used in hazardous area is shown below. The cable shield is not connected to the load cell body and shall be connected in the other end. -
Page 12: Mechanical Installation And Maintenance
User Manual Mechanical installation and maintenance Load cells of the line KxxD-(D) are designed to be supported at both ends and loaded at the middle of the cylindrical body (KIMD, KOSD and KISD). An arrow on one or both ends defines the correct direction of the resulting force from the applied load. At the cable/connector end of the load cell, a flat reference surface or key slot are provided (KIMD, KOSD and KISD). - Page 17 Load cell KxxD-(D) IECEx Certificate The IECEx certificate for the KxxD (-D) Load cell can be found on the official IECEx web site: http://iecex.iec.ch Certificate number: IECEx BAS 14.0015X Issue No: 2. Function safety Certificate The functional safety certificate for the KxxD (-D) Load cell can be found on TÜV Rheinland web site: www.fs-products.com and www.certipedia.com/fs-products...
