F232/3 Multi-Axis Loadcell
The F232 measures forces in two axes at 90° and the F233 measures forces in 3 mutually perpendicular axes. Apart from error evaluations, each output is pure and requires no mathematical manipulation.
The loadcell is moment sensitive requiring calibration to be carried out at a specified force centre. The standard centre is specified in the specification. If this is not suitable for your application please consult our engineering department about alternative calibrations.
The F232/3 is ideally suited to many industrial and scientific applications, including automotive and medical research.
The loadcell can be manufactured with force ranges to suit the application. The Z axis can have a different force range from the X and Y axes. Please consult our engineering department about the viability of the required ranges. The example shown in the picture and drawing is a 500N model; there will be small differences in the dimensions for other ranges.
We are happy to design variants of this loadcell to meet your specific requirements. Other types of multi-axis loadcell can be supplied with ranges up to 20kN. Versions can be manufactured for higher temperature operation. Please consult our engineering department.
Additional information on specifying a multi-axis loadcell can be found in Engineering Sheet E015.
