The ORR-FU30 Multi-Axis Sensor from ORR Sensor Co., Ltd. utilizes advanced strain gauge technology to provide high-precision measurement with accuracy up to Class 0.5. Designed to minimize crosstalk interference between signal channels, the ORR-FU30 ensures stable and reliable performance in demanding industrial environments.

Modern load cells work using a combination of the Wheatstone bridge equation and the strain gauge. The Wheatstone bridge equation was developed in 1833 by Samuel Hunter Christie, and improved upon and popularized in 1843 by Sir Charles Wheatstone. Wheatstone bridge circuits illustrate the concept of a difference measurement. Today, load cells are usually made up of four strain gauges in a Wheatstone configuration.

The basic principle, it is a measure of the “force” being used (or attempting) to turn an element. This measurement is achieved by the use of strain gauges bonded to the shaft, measuring the strain, induced in the shaft by the applied torque or “force”.

① Repeatability: The maximum difference between load cell output readings for repeated loadings under identical loading and environmental conditions. ② Resolution: The smallest change in mechanical input which produces a change in the output signal. ③ Sensitivity : The ratio of the change in output to the mechanical input.
