Description
F332 2 Axis Loadcell
The loadcell is ideally suited to many industrial and scientific applications, including medical research and biometrics.
The recessed input fixing removes the possibility of applying any force to the delicate strain system during transport, storage or general handling. The design of the case is such that there is a degree of in-built overload protection during normal use. Input torque to the live force input fixing must be minimal, normal frictional torques achieving thread insertion should not be exceeded i.e. thread locking by adhesive is suggested.
If large moment arms are present the performance specification may be affected. It is best to contact members of our engineering department, who will be happy to evaluate performance changes. The loadcell can be manufactured with dimensions, fixings and force ranges to suit the application. Please consult our engineering department about the viability of all required design changes.
The example shown in the picture and drawing is a 0.1N (10gf) model; there may be some small enforced differences in the dimensions or fixings for custom force ranges.
We are always happy to design variants of this or any other standard loadcell product to meet your specific requirements.
Additional information on specifying a multi-axis loadcell can be found in Engineering Sheet E015.
