The unit's stable temperature response ensures reliable operation over an extended temperature range of -55 degrees C to +163 degrees C, making this triaxial IEPE accelerometer useful in high temperature, high frequency, shock and vibration testing.

In addition to its specific uses in automotive testing and laboratory environments, the Model 7132AHT is ideal for many general purpose data acquisition applications, due to its exceptional performance characteristics.

The sensor uses stable piezo-ceramic crystals in annular shear mode for long term, stable operation as well as offers flat frequency response across a wide bandwidth up to 10 kHz. In addition, the Model 7132AHT features residual noise as low as 0.001 g RMS (@ +/-50 g), with a maximum of only 0.005 g RMS (@ +/-2,000 g).

Output impedance is more than 100 Ohms and full scale voltage output is +/-5 V across all dynamic ranges. Other notable parameters include an excitation current of 2 mA to 10 mA, a compliance voltage of 22 VDC to 33 VDC, transverse sensitivity of less than 5% and non-linearity of +/-1% FSO.

A hermetically-sealed, titanium housing enables the unit to withstand harsh elements in rugged environments. The 4-pin miniature connector interface securely fastens the accelerometer to the system cable for uninterrupted data transmission.

The 15-gram sensor can be adhesive or stud-mounted, depending on application requirements.
