Kistler has announced that its 8763B050 triaxial accelerometer is now more sensitive than ever, with the devices’ measuring threshold improved from 0.0004 to 0.00029 g; marking a significant enhancement in the field of vibration monitoring, where this sensor is primarily used.
The IEPE (Integrated Electronics Piezoelectric) 8763B050 is the most common Kistler sensor used for such measurements and permits vibration monitoring in three mutually perpendicular axes. The measuring threshold determines the smallest possible level of vibrations that can be reliably picked up by the sensor. Thanks to improved electronics, the 8763B050 has a threshold of only 0.00029 g, compared to previously 0.0004 g.
Type 8763B sensors provide wide frequency response in each orthogonal axis, making them well suited to dynamic vibration measurements, especially on lightweight structures. Other features include the sensors’ lightweight hermetic titanium housing and high immunity to base strain thanks to shear element technology. Additionally, a miniature 4-pin ceramic-insulated connector provides long-term stability over a large operating-temperature range. An integral silicone cable variant is available for application of underwater vibration testing at up to 10 bars.
8763B-family sensors can be installed on test objects by either adhesive mounting or by flexible studs thanks to three 5–40 threaded holes. This allows for fully utilizing each mounting side of the cube design and provides reliable mounting for the calibration of each axis.
