The beam has three transverse through ho-les. Variations include a type of miniature tension and miniature compression load cell. 0000005724 00000 n It is a more costly technology and thus cannot effectively compete on a cost of purchase basis 13. The different types of load cells in use include strain gauge cells, pneumatic load cells, and hydraulic load cells. Bending beams high strain levels at relatively low forces with greater deflection compared to other measuring principles. All Massload custom designed Load Cells are … Hydraulic Load Cell: Limitations: This technology is more expensive than other types of load cells. 0000001109 00000 n A load cell is a transducer that converts the mechanical force into readable electrical units, similar to our regular weighing scales. Hydraulic load cells 2. 28 0 obj<>stream The preferred excitation voltage is 10 VDC, which guarantees the user the closest match to the original calibration performed at Interface. The last type of load cell we are going to discuss is a capacitive load cell. A load cell is meant to measure the size of a mass but actually is a force sensor which transforms force into an electrical signal. 3. According to the way they detect weight. Interface load cells all contain a full bridge circuit, which is shown in simplified form in Figure 1. Based on precision, load cells can be classified as ultra precision, precision, standard, and general-purpose. The ultimate overload capabilities are therefor excellent. existing load cell tables have to be supplemented each time a new load cell type is added. The load cell structure (spring element) materials are typically, but not limited to, carbon steel, stainless steel, or aluminum. Within our product family are numerous types of micro load cell that are ideally suited to applications where space is a limiting factor.
