1 Full-ridge Strain s escription M 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 (EM). The EM gauges are mostly for manufacturing low-cost force transducers, because with the EM 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 M SENSOR. For more information on temperature compensation (ST), creep compensation, and EM of strain gauges, please refer to the corresponding articles respectively on the website of M SENSOR.
