Offered in five different models with available measurement ranges from 2 to 100 g, the Endevco model 7290D series from Meggitt Sensing Systems incorporates a variable capacitance (VC) sensing element with gas damping and internal over-range stops. This sensing element allows it to survive significant shock and acceleration loads of up to 10,000 g, with 2.5% total dynamic accuracy. Available with Transducer Electronic Data Sheet (TEDS) capabilities, the unit features a non-linearity, including hysteresis, of typically 0.2% for ranges of 2 to 5 g. An integral custom signal conditioner enables the device to accept 8 to 30 V inputs. The ±2.25 V differential output (single-ended output optional) is DC coupled at a bias of approximately 2.5V. 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. The accelerometer is shipped standard with an integral cable of customizable length. Models are also available with an optional triaxial mounting block, the Endevco model 7990.

With the April issue, we celebrate the 40th anniversary of IEN Europe. For that occasion we present numerous interesting articles and interviews on technologies that have been groundbreaking over the past decades. An interview with Nexans is on the Evolution of Cables . A technical article by the EMVA on Machine Vision emphasizes the milestones that have been important for the automation industry. A very recent and up-to-date topic, Industry 4.0, is discussed in an Interview with Wibu Systems, a company dedicated to the protection of know-how. IEN Europe April also features a retrospective on Low-voltage Switchgear by Eaton. To celebrate IEN’s 40th anniversary properly, we have a Reader Offer for you, where you can win a high-tech visual IR thermometer. So please celebrate with us and enjoy!
