MODEL EGAS ACCELEROMETER SPECIFICATIONS Miniature Design, Light Weight DC Response, Critically Damped 10,000 g Over-range Stops Broad Temperature Range The Model EGAS is a miniature, uniaxial accelerometer featuring ranges from 5g through 2500g. This rugged unit weighs less than 1 gram (without leads) and has an over- range limit of 10,000g s. The active bridge is suitable for shunt calibration. With an operating temperature range of - 40C to +120C, the EGAS is the unit of choice for measurement professionals in the automotive, military, aerospace and transportation industries. Its combined dimensions nonlinearity and hysteresis of 1% makes the EGAS well- suited for on-site testing as well as laboratory use.
