Description
Type 8766A... is an IEPE triaxial accelerometer designed for high
temperature applications. Type 8766A… accelerometer uses
Kistler’s PiezoStar shear element design which provides a wide
operating frequency range and extremely low sensitivity to tem-
perature changes, as shown in Figure 1 (see pg. 3). The IEPE
sensor combines PiezoStar crystals and high gain integral hybrid
microelectronics to achieve very low sensitivity variation over the
operating temperature range, compared to other sensing element
designs. The Kistler shear element technology also ensures high
immunity to base strain errors. The accelerometer uses a welded
titanium construction for low mass and an industry standard 4pin
connector, as well as a mini 4 pin connector for lower mass and
wider frequency operation. An integral silicone cable variant is
available for application of underwater vibration testing at up to
10 bars [150 psi]. All variations provide reliable measurements and
long-term stability, especially at higher operating temperatures.
• IEPE, 50 ... 1,000 g ranges

Mounting
Reliable and accurate measurements require that the mounting
surface be clean and flat. The sensor can be attached to the struc-
ture with wax, adhesive or the supplied mounting stud. Several
optional ground isolated mounting accessories are also available
for added mounting flexibility. Type 8766A250/500/1K0..., with
three 5-40 UNC-2B threaded holes, and Type 8766A050/100,
with three 6-32 UNC-2B threaded holes, offer flexible stud
mounting on a test object, fully utilizing each mounting side of
the cube design. In addition, the three threaded holes provide
reliable mounting for calibration of each orthogonal axis. The
instruction manual for Type 8766A… provides detailed informa-
tion regarding mounting surface preparation.
CAUTION: The 50 g range contains a high output Piezostar
element combined with a sensitive electronic. Use care when
handling the sensor during mounting and un-mounting, es-
pecially when using a magnetic base or releasing the sensor
from adhesive mount. Failure to do so may cause irrepairable
damage to the sensor.

Application
This miniature and lightweight triaxial accelerometer family is
ideally suited for structural analysis of small components or sub-
systems, full vehicle testing for aviation, space, and automotive,
as well as a wide range of general test structures. The PiezoStar
accelerometer technology excels in operational testing over
dynamic test conditions.
