Variable-capacitance accelerometer

The Endevco Model 7298 triaxial, variable-capacitance accelerometer is for highly accurate measurement of low-frequency events. The units are available in six models, ranging from 2 to 100 gm, and feature a sensing element with gas damping and internal overrange stops, which allows the transducer to withstand high shock and acceleration loads. It also features a stainless-steel, hermetically sealed package with a water-resistant connector that, when combined with an optional Model 3907 cable assembly, allows for extended outdoor exposure. Additional features include a broad excitation input range from 6 to 45 Vdc; operates across the full military temperature range of –55 to 125°C with integral digital temperature compensation; and easy installation with simple two-screw mounting. In addition, it offers +0.5% FSO typical nonlinearity and hysteresis for most ranges and +1% FSO maximum for both thermal sensitivity shift and thermal zero shift, enabling it to provide the highest level of total accuracy available.Meggitt Sensing Systems, 14600 Myford Rd., Irvine, CA 92606, (949) 493-8181, www.endevco.com
