Meggitt Sensing Systems Introduces the Endevco® Model 7257AT Piezoelectric Accelerometer for Flight Vehicles
Units Offer Sensor and Airborne Amplifier Functions in One Integrated Package
San Juan Capistrano, California, USA - Meggitt Sensing Systems has introduced the Endevco® model 7257AT, a compact, hermetically sealed piezoelectric accelerometer with integral electronics, designed for vibration measurements on flight test vehicles, particularly ones that incorporate telemetry as their chosen data acquisition system. The distinguishing feature of this accelerometer is that it offers the functions of both flight test accelerometer and airborne amplifier in one small package. It is the only sensor of its kind on the market today.
Available in six model variations, with choice of 10 mV/g or 100 mV/g sensitivity and upper corner frequency ranges from 500 to 5000 Hz, the Endevco® model 7257AT offers a ±2.5V full scale output, biased at +2.5Vdc, which can be directly interfaced with many different types of telemetry systems. The sensor's unique three-wire configuration offers fixed voltage input, with a built-in four-pole Butterworth low-pass filter that provides necessary out-of-band signal suppression, typically required for telemetry-based applications. In addition, the sensors can be powered by any flight vehicle standard +15 to +32 Vdc supply, and are electrically case isolated from the mounting surface. A center through-hole mounting configuration allows for 360° cable orientation and greater application flexibility.
A recommended accessory for use with the model 7257AT is the Endevco® model 6917M2-XXX, a directly compatible cable terminating with pigtails.
