They are based upon bonded semi-conductor strain gauge technology, conferring excellent sensitivity and eliminating the fragility associated with unbonded strain gauge types. The design features excellent immunity to the effects of eccentric loading, side loading and bending moments. Forces may be applied either in tension or compression and alternative loading adaptors are available. The low deflection and consequent high frequency response ensures that the unit is suitable for measuring peak and transient forces. The transducer will replace the well known UC2 and UC3 range of load cells, originally marketed by Gould-Statham®, who stopped production in the 1980’s. There are many applications for this range of load cells in medical applications, research and development and industry.
