he 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 self-temperature compensation (STC), creep compensation, and EMC of strain gauges, please refer to the corresponding articles respectively on the website of BCM SENSOR.
