Three-Wire Piezoelectric 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.
Certified by multiple approvals from the Canadian Standards Association (CSA) in North America and by LCIE in Europe.
Installed in 43217 (standard) or 37442 (high-temperature) housings to protect against adverse environmental conditions. Mounts the accelerometer onto the surface of the monitored component for optimal frequency response.
Three interconnect cables available with a threaded female connector at the accelerometer end and terminal lugs at the monitor end. Standard cable suitable for most installations. Standard cable lengths range from 6 ft (1.8 m) to 99 ft (30 m). Non-standard lengths available as custom options.
