Meggitt Sensing Systems introduces TEDS capabilities into Endevco® model 7290D variable capacitance accelerometer series

Meggitt Sensing Systems, a Meggitt group division, has announced the recent introduction of Transducer Electronic Data Sheet (TEDS) capabilities into its industry best-selling Endevco® model 7290D series, allowing it to be used within larger channel count applications. The model 7290D series is a high-accuracy, variable capacitance (VC) accelerometer family, offering exceptional thermal stability, reliability and performance within flight test, engine testing and other extreme temperature testing environments.

Offered in five different models with available measurement ranges from 2 g to 100 g, the patented design of the Endevco® model 7290D series (U.S. patents 4,574,327; 4,609,968; and 4,999,735) incorporates a VC sensing element with gas damping and internal over-range stops, allowing the sensor to survive significant shock and acceleration loads of up to 10,000 g, with 2.5% total dynamic accuracy. Units feature excellent non-linearity, including hysteresis, of typically 0.2% for ranges of 2 g to 50 g.

Integral to each accelerometer is a custom signal conditioner, enabling the device to accept input voltages from 8V to 30V with a high level, low impedance output. The ±2.25 V differential output (single-ended output optional) is DC coupled at a bias of approximately 2.5V. In order to maintain stringent thermal characteristics and high accuracy, a custom ASIC provides factory programmable temperature compensation, achieved via five-point linear fit algorithm, for both thermal sensitivity and thermal zero shifts. Units are integrally temperature compensated from -55° to +125°C, to ensure temperature accuracy over the full military range. TEDS capabilities (conforming to IEEE 1451.4) allow for onboard storage of serial number and calibration data, for simplified test setups with reduced errors.

All Endevco® model 7290D series units are shipped standard with an integral cable of customizable length. Models are also available with an optional triaxial mounting block, the Endevco® model 7990. Recommended accessories for use with the Endevco® model 7290D series include the model 136 three- channel signal conditioner; the model 4430A bridge transducer signal conditioner; or the model 4990A (Oasis) multi-rack based signal conditioning system. In addition, all Endevco® products are accompanied by a comprehensive five-year product warranty.
