Load cell selection guide Selection Criteria is based on: Application- Describe requirements in details-suitable model will be suggested by application. Environment- Indicate if it is humid, water logged, submerged, corrosive and temperature etc.-suitable load cell material of construction and suitably protected load cell will be selected based on this input. Rated Load- Give expected load along with tare load for calculation of capacity of cell-capacity will be calculated based on these data. System configuration and no. of Load Cells required- Model and capacity will be calculated. Requirements of Mounting hardware and Instrumentation- Suitable mounting assembly and instrumentation will be selected. If proper details are provided, we can suggest best configuration suitable for your application.

Excitation Voltage - Generally nominal DC 10 Volt is used. Max. allowed 15VDC. Remote Sensing of Excitation Voltage - If cable length is larger than 25 Mtrs., this configuration is recommended to avoid the influence of cable resistance into the measurements. Physical Mounting: “Dead” and “Live”- End-user has to install the load cell properly. Refer suitable catalog. Loading Direction-refer catalog Mounting Torque-refer catalog

Proper grounding and shielding is critical to the successful application of load cells generating low level signals. The basic rule is that continuous ground loops should be avoided, i.e., a system should not be grounded at multiple points. The load cell cable shield to be grounded at instrument end. Interface load cell cables are supplied with a braided shield which provides protection from electrostatic interference when properly grounded. This shield is floating (not connected) at the load cell end so that a ground loop will not be inadvertently created. A basic system layout that is easily achieved and usually is satisfactory is as follows: *The load cell case is grounded by mechanical attachment to the structure to which it is mounted. *This structure should be properly grounded to the electrical circuits which drive the excitation for the load cell. *The braided shield enclosing the load cell leads is grounded at the instrument and the instrument is grounded through the power cord.
