402.I51 : Uniaxial Piezo Top (Standard)

Competitive Advantage

The InstantVib® IEPE Industrial MEMs accelerometer model 402 is engineered for reliable vibration monitoring in demanding industrial environments. It utilizes the industry-standard ICP/IEPE 2-wire voltage transmission technique, enabling distortion-free transmission of a 20 kHz AC signal over distances up to 100 meters with a 4 mA constant current supply. To eliminate ground loops, the signal ground is isolated from both the mounting surface and the outer case. Its IEPE compatibility allows seamless integration with a wide range of instruments, including FFT analyzers, data acquisition cards, and data collectors. The inclusion of TEDS compatibility further simplifies automatic calibration with these devices. While screw mounting is recommended for the full 20 kHz bandwidth, magnetic mounting is also available for quick medium-frequency measurements below 2 kHz.

Typical applications:

The Model 402.I51 IEPE industrial MEMs accelerometer offers exceptional versatility, effectively replacing many specialized IEPE piezoelectric industrial accelerometers. Its quasi-static (0.1 Hz) capability and ultra-low noise (300 μg/√Hz at 0.1 Hz) make it perfect for monitoring very slow-speed equipment like agitators, cooling towers, and turbines in various industries. It also handles high-dynamic applications (over 50g) such as balancing pumps, motors, and fans with ease. Our patented electronics ensure stable velocity measurements after integration, vital for general industrial vibration monitoring, and its low noise (60 μg/√Hz at 0.5 Hz) enables velocity monitoring of machines down to 30 RPM. The sensor's precision in measuring micro-g shocks within a noisy 100 g range allows for advanced bearing and gear analysis using InstantVib® IEPE MEMS technology. This innovative accelerometer transforms measurement practices, delivering new value and reducing total ownership costs.
