Full-Bridge Strain Gauges for Force Transducers
BCM SENSOR full-bridge strain gauges are specially developed for manufacturing precision force transducers which
employ bending beam working principle. For the purpose of this specific application, the full-bridge strain gauges are
temperature and creep compensated, and they can be either encapsulated or open-face according to the requirement.
The karma gauges can be manufactured with effective modulus compensation (EMC). The EMC gauges are mostly for
manufacturing low-cost force transducers, because with the EMC gauges the manufacturers can eliminate the use of
compensation resistors and achieve the sensitivity compensation.
For creep compensation, there are 18 creep codes: “N10, N9, N8, ..., O, ..., P5, P6, P7". The “N10” is the most negative
creep code, while the “P7" is the most positive one. The “O” stands for a moderate creep code. For a specific strain
gauge, please find its available creep code below its dimensions at the “Option *9" on the following pages. For a
customized creep code, consult BCM SENSOR.
For more information on temperature compensation (STC), creep compensation, and EMC of strain gauges, please refer
to the corresponding articles respectively on the website of BCM SENSOR.
Ordering Information
Description
Notes: (1) The center distance of two grids only applies to the half-bridge and full-bridge strain gauges.
(2) The length of the leads and wires can be customized on request.
(3) The highest operating temperature of enamel insulated copper wires (CW) is 150°C.
