vibration sensor application

First, define the frequency range of interest. For concrete dams, structural modes are typically below 100 Hz, so a low-noise accelerometer with good low-frequency response (down to 0.1 Hz or lower) is needed. Consider the output: 4-20 mA is robust over long cable runs, but if you need dynamic waveform data, a voltage output sensor paired with a local DAQ is better. Also factor in waterproofing and corrosion resistance—look for IP67 or higher stainless steel housings. We often supply sensors with custom cable lengths and integrated surge protection for lightning-prone areas.

Yes, but you need intrinsically safe or explosion-proof certifications. For mining, we provide ATEX-certified accelerometers with armored cables. These are designed for continuous vibration monitoring on conveyor drives and crushers. The mounting method also changes: drill-and-tap stud mounts are standard, but in hazardous areas you may need bonding straps to prevent static buildup.

It depends on the environment, but with proper sealing and strain relief, piezoelectric sensors can last over a decade. The failure points are usually the cable connection and moisture ingress. We recommend stainless steel connectors and regular inspection of the cable near the sensor. For long-term projects, we supply spares so that swapped units can be recalibrated offsite.

We can integrate our sensors with third-party wireless nodes that support 4-20 mA or MODBUS inputs. We don’t build the wireless transmitter ourselves, but we ensure the sensor’s output and power requirements match, and we can pre-configure cables and connectors for a plug-and-play setup.

For permanent installations, we provide curved mounting bases or magnetic clamps with the correct radius. The key is to avoid air gaps between the sensor base and surface. A thin layer of silicone grease improves high-frequency coupling. If welding a base, do it before the sensor is attached to avoid heat damage.
