The operating principle of the FLINTEC UB1, S-type strain gauge is based on the conversion of tensile/compressive strain along the principal stress areas of the elastic element into an electrical signal. Strain gauges, normalization and temperature compensation elements are connected using a Wheatstone bridge circuit.
UB1 sensors are used as components in weighing (force measuring) and weight dosing systems, scales of III (medium) accuracy class according to GOST 29329 and RM MOZM No. 76.
It is recommended to use it complete with hinge lugs (installation unit type 53-04, see below).
