Measurement Specialties debuts miniature accelerometer

Feb. 27, 2015

Measurement Specialties, now part of TE Connectivity, has released the Model 7132AHT, a high-temperature, miniature accelerometer with nonlinearity of ±1% FSO across dynamic ranges from ±50 g to ±2000 g.

The unit’s stable temperature response ensures reliable operation over an extended temperature range of -55°C to +163°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 suitable for many general-purpose data-acquisition applications.

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 (at ±50 g), with a maximum of only 0.005 g RMS (at ±2,000 g).

Output impedance is more than 100 Ω 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, and transverse sensitivity of less than 5%.

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-g sensor can be adhesive- or stud-mounted, depending on application requirements.
