Meggitt Introduces High-Temperature IEPE Accelerometer with Low-Pass Filtering

Meggitt, the leading innovator of sensors for test and measurement applications, announces the global market introduction of Endevco® model 27BLPF accelerometer.

Meggitt’s highest temperature, single-axis IEPE accelerometer features an integral two-pole low-pass filter and comes in a miniature, lightweight package.

The latest addition to the model 27 family has a 10 mV/g sensitivity and operates reliably up to +175°C (+347°F). Two standard options are available; the 27BLPF-10-02 has a 2 kHz corner frequency and the 27BLPF-10-10 has a 10 kHz corner frequency.

Low-pass filtering at 2 or 10 kHz enables attenuation of high-frequency, high-g signals in order to prevent obscuring low-frequency data of interest. Potential applications that will benefit from low-pass filtering include vibration measurements on compressors, during flight tests (aircraft, launch vehicles, missiles) and during vehicle testing. Two-pole filtering provides a steeper roll-off than competitive miniature sensors, which have a single-pole filter.

The adhesively-mounted 27BLPF miniature sensor has a 0.25 inch diameter and weighs 0.8 grams, minimizing mass loading on the test structure. The teardrop-shaped titanium housing is hermetically sealed, has a side-exit M3 connector and comes standard with a 10-foot mating cable.

Included accessories are petro-wax adhesive for temporary installations, an isolating mounting pad, and a removal tool. The 27BLPF-10-XX-R is available at specially discounted rates under the –R replacement sensor program.

Compliant to the European Union Low Voltage Directive 2006/95/EC and EMC Directive 2004/108/EC, the 27BLPF is eligible to bear the CE mark. Units are available for immediate delivery. The 27LBPF is compatible with signal conditioner models 123, 133, 2793 and 2775B, sold separately.

For test applications where high-temperature vibration measurements with low-pass filtering are needed in a triaxial configuration, Meggitt offers model 65HTLPF-10. All sensors in the Endevco® product line are accompanied by a comprehensive five-year product warranty.
