high sensitivity accelerometer

Sensitivity is simply the voltage output per g of acceleration. Standard industrial accelerometers sit around 100 mV/g, which works for large machinery but not for ambient vibration. If your signal level is consistently below 1 mg, a high‑sensitivity model (1 V/g or more) gives your data acquisition a cleaner input and uses more of its dynamic range. That shows up in better signal‑to‑noise ratio and less need for post‑processing gain.

It depends on what you are measuring. For thick concrete structures, you need response down to 0.2 Hz or so. Turbines and gearboxes may want the flat band to reach 5 kHz. Kingmach can shift the resonant peak of the sensing element by changing the mass and stiffness. We ask for your target low‑ and high‑frequency corners during inquiry so the sensor arrives calibrated within those limits. A sample spectrum of your expected vibration also helps us pick the right damping.

Yes, for most terrestrial environments. Our default seal is IP67 with dual‑stage O‑ring glands, and the stainless‑steel housing takes direct sun, rain, and dust without degrading. For submerged or splash‑zone use you can upgrade to IP68 with a welded‑on integral cable. We also conformal‑coat the internal PCB. Marine‑grade connectors with gold‑plated pins are available if corrosion is a concern.

IEPE (constant current powered) is the most common—it lets you run coax or a simple two‑wire pair over long distances using the same lines for power and signal. Charge‑mode accelerometers need a separate charge amplifier, but they handle higher temperatures and have a flatter phase response. For monitoring networks, we also offer 4‑20 mA and Modbus RTU outputs. The choice usually boils down to your existing DAQ and how much you want to avoid adding conditioners in the field.
