Load cell is a type of device that can transform the weight or force signal into the determinable electrical signal output. Generally, it can connect with a special digital panel meter for obtaining the direct readings or connect to a load cell transmitter and amplifier to an output standard signal. At the present moment, the resistance strain gauge load cell is the most common load cell which makes the use of the principle that the resistance alters which is respectively the elastic part, resistance strain gauge, measuring circuit as well as the transmission cable.
Mainly load cells have many types like:
- Single point load cell
This is most commonly used for weighing scale or pricing scale. This is well suited to be used in flat and low space that comes with parallel beam structure, good output symmetry, good stability, high accuracy, overload protection, and low temperature drift.
- Strain gauge load cell
This can bear both tension as well as the pressure with the great output symmetry, high accuracy, complete specifications, and compact structure. The strain gauge load cell can be implemented for the batching scale, crane scale, electronic mechanical scale and other force value measurement and control.
- Micro load cell
This type of load cell can also bear both pressure as well as tension with great stability, high accuracy, good output symmetry, low temperature drift, complete specifications, and compact structure. The micro load cell is best to be used in the restricted spaces.
- Tension and compression load cell
The tension and compression load cell can also bear both pressure as well as the tension with the great output symmetry, compact structure, high eccentric load resistant, and complete specifications. This strain gauge load cell can be implemented for the batching scale, crane scales and other special weighing equipment.
- Miniature tension and compression load cell
Miniature tension and compression load cells can tolerate both compression as well as tension force with the help of metal foil strain gauge, small size, all stainless steel and 1.0±0.2mV/V sensitivity. This load cell is utilized in force tester, laminator, riveting machine, and welding machine.
- Compression button load cell
This is a compression load cell that has a diameter of 10 mm. It bears a capacity range from 5 to 100 kgs. The Button load cells can be used for medical testing, 3C product testing, automated equipment testing etc. It can also be designed in a customized way for the high temperature working condition.
