Evaluating a Load Cell Based on Your Operational Specifics
Posted: Nov 08, 2017
There is no comprehensive handbook that can decide the right kind of load cell for your operations. It’s entirely a matter of one’s choice and understanding of their scope of operation. However, knowing certain features may help you wrap your head well around the workings of a load cell, and in the process, see more clearly the uses of these engineering devices. So, whether you are out evaluating a shear beam load cell or a regular compression Load cell type, here are evaluating qualities that can help you find the load cell that best suited to your operation types and needs.
Output Requirements: There are three kinds of output modes in a load cell, namely, digital, analog and wireless. Considering this day and age, a wireless device seems more fitting than an analog one. However, a analog output device is a fair medium between the two, since the products are designed for tropical conditions, Digital Loadcells are ideal for use in protected environment. The Digital Load cells are more prone to failure due to surge voltage.
Duration of Measurement: When Loadcell needs to be used for weighing for prolonged period, as in Silo or Tank weighing application, the Creep factor in Load Cell need to be taken into consideration along with the tare weight of the structure. Suitable capacity has to be considered taking into consideration the above factors, without sacrificing on the accuracy
Speed of Measurement: Normally, the speed of measurement of a load cell or the Response time of Load cell is inversely proportional to the deflection. The Lower the deflection, faster will be the settling time, our Sensomatic Load cells range starts from 28msec to 60msec for most products.
Loading Directions: The Load Cells are commonly used in Tension or Compression mode or in Universal Mode (Both in Tension & Compression mode).
Degree of Accuracy: The Accuracy of Load cell or combined error is normally specified for full load & this should not be misinterpreted that the same accuracy will be applicable for lower ranges.
Thermal Conditions: Determining the temperature conditions of your work environment is crucial to your selection of a load cell. Are you going to use it in an outdoor or indoor temperature? Is the environment well-controlled or inclement? The Load Cells are normally Temperature compensated to work upto 80 Deg C (for standard products, by reputed manufacturers & the Loadcell can also be compensated to work under elevated temperature condition upto 180 Deg C. Also the Ingess Protection helps in deciding the working of Loadcell in humid conditions. Stainless Steel Load cells solve most of the issues when operating under humid & corrosive condition
Mounting Options: Load cells have multiple application & based on each specific application, the mounting can be modified.
Cost of Operation: Before you get your load cell, try to figure out the operation costs. Some are designed to handle bulk volumes of good which makes them a good pick for larger operations. For smaller quantities, you want to pick those that are particularly engineered to handle small loads without shooting up the operation costs.
