Strain Gauge Load Cell Calibration

Strain gauge load cell weighing systems convert weights into analog output signals that can be further conditioned to indicate weight in digital meters and control systems.

Strain gauge load cell calibration.

In a load cell the resistors are replaced with strain gauges and arranged in alternating tension and compression formation. From the resulting data v o can be easily determined using the equation above. The load cells are commonly used in industrial processes where the weight of certain products is measured. We also offer in house load cell repair traceable or ukas accredited load cell calibration as well as an equipment hire service.

Common types of load cells. There are several types of strain gauge load cells. While there are many types of force sensor the strain gauge load cell is the most common. Our in house design team build bespoke customer load cells.

In a load cell these resistors are replaced by strain gauges in alternating tension and compression measurements. Strain gauge load cells usually feature four strain gauges in a wheatstone bridge configuration which is an electrical circuit that balances two legs of a bridge circuit. This is because strain gauge load cells can offer accuracies from. Strain gauge load cells are by far the most common type of load cell based weighing system in 2010.

Strain gauge load cells should be calibrated by applying dead weight loads or hydraulic piston loads monitored by a proving ring or reference load cell. When force is exerted on the load cell the structure and resistance of the strain gauges changes and is measured. A load cell sometimes called a load cell transducer or load sensor is a force gauge that consists of a transducer. When a force is applied to the load cell the resistance in each strain gauge changes and v o is measured.

The various load cell types include pneumatic hydraulic and strain gauge. The wheatstone bridge used in strain gauge load cells are typically field calibrated using the shunt calibration technique. From the resulting data can be easily determined using the equation above. We configure strain gauge installations to customer requirements in house on site static dynamic 269 c 1000 c steel composite etc.

This transducer converts a mechanical force such as tension compression or pressure into a measurable electrical output. The load cells can be used for the precise weight measurement if properly calibrated. The force being measured deforms the strain gauge in this type of load cell and the deformation is measured as change in electrical signal.
