Vibration Accelerometers That Handle Real-World Conditions
A vibration accelerometer that delivers clean data in the lab is one thing. Keeping that performance after being bolted to a diesel engine or buried in a dam for a decade is another. Kingmach vibration accelerometers are designed with that reality in mind. Our focus isn’t on chasing the highest possible specs on paper, but on consistent, credible readings across temperature swings, humidity, and electrical noise. This comes from practical design choices like robust housings, shielded cabling understanding from thousands of geotechnical and structural health installations worldwide. With options for IEPE and charge output, a range of sensitivity to capture everything from subtle seismic murmurs to heavy vibration on crushers, and standard IP67 sealing as a starting point, you can match the instrument to the site, not the other way around. And when standard isn’t enough, our customization covers mounting adapters, cable lengths, and calibration to specific frequencies. The result is a monitoring chain that engineers trust, supported by a team that answers questions from installation to data interpretation.
Technical Detail
Kingmach builds vibration accelerometers for people who put sensors where it’s hard to reach and harder to replace. The core of our design philosophy is reliability without unnecessary complexity. Sensitivity options span from 10 mV/g up to 500 mV/g, so you aren’t forced into an amplifier’s noise floor or clipping ceiling. Frequency response is tailored to the application: a wide flat band for machinery diagnostics, or a low-frequency roll-off that protects against thermal drift when monitoring slowly-varying structures. Construction choices matter when installations involve high humidity, dust, or occasional submersion. We default to IP67 rated stainless steel bodies. For accelerometers destined for underwater use, we’ll seal them further and pressure-test connections. Cable integrity is often the weak link; we solve that with ruggedized cables with strain relief at both sensor and connector ends. Mounting can be via standard stud, magnetic base, or adhesive pad — the latter used where drilling isn’t allowed. What sets us apart isn’t just the hardware. Kingmach supplies globally with technical support that bridges time zones. We keep stock of common models and can customize within weeks for larger orders. Our engineers regularly help with signal conditioning setup, data acquisition compatibility, and even field calibration checks. Whether your project is monitoring a heritage bridge, a wind turbine gearbox, or an underground mine crusher, we can propose a vibration accelerometer that fits the electrical, mechanical, and environmental constraints. Ask for a technical consultation — we’ll ask the right questions before quoting.

FAQ
Start with the acceleration range you expect. For heavy machinery (50–500 g), a lower sensitivity like 10–50 mV/g avoids saturation. For seismic or structural measurements below 1 g, a higher sensitivity (500 mV/g) gives better resolution. Also check your data acquisition input range — you want the accelerometer’s output to use most of that range without clipping.
Standard Kingmach accelerometers carry IP67 rating, meaning protected against temporary immersion. For permanent underwater use, we offer customized sealing and testing. Always confirm the connector environment; we can provide molded cables or additional booting for heavy rain exposure.
Yes. Each unit ships with a standard calibration certificate traceable to industry standards. We can also arrange for accredited lab certification at additional cost. Mounted resonance checks and frequency response plots are available on request.
