Three-Wire Piezoelectric Accelerometers

330400/330425 Accelerometers

Our 330400 and 330425 3-pin Accelerometers are appropriate for highly critical machinery applications where casing acceleration measurements are required, such as gear mesh monitoring.

These accelerometers monitor vibration frequencies from 10 Hz to 15 kHz and require -24 Vdc to power the internal charge amplifiers.

The 330400 meets the requirements of the American Petroleum Institute Standard 670 for accelerometers. It provides an amplitude range of 50 g peak and a sensitivity of 100 mV/g.

The 330425 also meets the AMI Standard 670 while offering a higher amplitude range of 75 g peak and lower sensitivity of 25 mV/g.
