Meggitt Sensing Systems Introduces Portable, Low-noise Battery Powered Endevco® Signal Conditioner for Accelerometer and Acoustic Test Setups



Meggitt Sensing Systems, a Meggitt group division, has announced the global market introduction of the Endevco® model 4416B, a portable, compact, low-noise battery operated signal conditioner and power supply, designed to support ISOTRON® (IEPE-type) accelerometers; prepolarized condenser microphones and preamplifiers; pre-calibrated microphone and preamplifier combination sets; and low-cost array measurement microphones, by supplying power to the transducer from a constant current (4.7 mA) source, with selectable gain of 1 or 10. The Endevco® model 4416B signal conditioner is powered by rechargeable NiCad batteries (supplied with charger), which allow for eight hours of continuous operation. The unit is also able to remain fully operational during the recharging cycle. An LED status indicator notifies the user of a short, open or normal operating condition, with the necessary internal automatic power shutdown circuitry to protect rechargeable batteries from deep discharge damage. The added flexibility of this signal conditioning unit allows for ease of customer use and seamless integration of the model 4416B across multiple test setups, ultimately saving time and costs within a variety of aerospace, automotive, industrial and general in-laboratory testing applications. All Endevco® signal conditioning electronics are backed by a five-year comprehensive product warranty, with select models available at specially discounted rates under Meggitt's Endevco® Incentives program.
