• Amplitude Linearity: ±1% to 490 m/s² (50 g) peak – Ensures consistent performance.
• Broadband Noise Floor: 0.039 m/s² (0.004 g) rms – Minimizes signal interference.

Frequency Response

The accelerometer offers an exceptional frequency response, making it suitable for a wide range of applications. Specifically:

• 10 Hz to 15 kHz (600 cpm to 900,000 cpm) ±3dB.
• 30 Hz to 10 kHz (1800 cpm to 600,000 cpm) ±10%.

Temperature Sensitivity

Designed to perform reliably under varying temperatures, this transducer features:

• -11% to +3% typical sensitivity over the operating temperature range.

Transverse Sensitivity

With a transverse sensitivity of less than 5% of axial, this accelerometer ensures minimal cross-axis interference.

Mounted Resonant Frequency

The transducer boasts a mounted resonant frequency greater than 30 kHz, ensuring stability and accuracy.

Amplitude of Resonant Peak

It features a maximum amplitude of resonant peak of 20 dB, providing clear and reliable signal output.

Base Strain Sensitivity

Depending on the serial number, the base strain sensitivity varies:

• For serial numbers preceded by the letter “G”: 49 mm/s²/mstrain (0.005 g/mstrain).
• For serial numbers NOT preceded by the letter “G”: 980 mm/s²/mstrain (0.100 g/mstrain) without Mounting Base; 4.9 mm/s²/mstrain (0.0005 g/mstrain) with Mounting Base.
