The Model EGAXT3 series represents the pinnacle of triaxial vibration sensing, tailored for test environments where compact, lightweight sensors are paramount. These accelerometers feature critically fluid-damped sensing elements, ensuring precise measurements even under extreme shock conditions, with protection up to 10,000g. Available in ranges from ±10g to ±2500g, the EGAXT3 provides versatile application capabilities, from subtle vibrations to significant impacts, with a frequency response up to 2000Hz, depending on the selected range. The series is designed for either epoxy or screw mounting, offering flexibility in installation setups. With inline temperature compensation, these sensors maintain accurate output across a broad operating temperature range of -40°C to +120°C. Enclosed in an environmentally sealed package with IP61 protection, the EGAXT3 accelerometers are robust tools for a variety of testing scenarios, including flight testing, transient drop testing, and both static and dynamic measurements.
