For the purpose of the 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.
