Datasheet

A high temperature, miniature accelerometer, the Model 7132AHT, has been released by Measurement Specialties, which is now part of TE Connectivity. Offering exceptional linearity across dynamic ranges from ±50 to ±2,000g, the device's stable temperature response ensures reliable operation over an extended temperature range from -55 to +163°C.

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

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

Output impedance is more than 100Ω and full scale voltage output is ±5V across all dynamic ranges. Other notable parameters include an excitation current of 2-10mA, a compliance voltage of 22-33VDC, 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 four-pin miniature connector interface securely fastens the accelerometer to the system cable for uninterrupted data transmission.

The sensor can be adhesive or stud-mounted, depending on application requirements. Pricing and delivery are dependent upon quantity.
