Machine and condition monitoring
Industrial manufacturing and power generation processes inevitably generate vibration and noise, particularly where rotating machinery is involved. In many environments, elevated operating temperatures further increase measurement challenges.
Uncontrolled vibration can lead to accelerated wear, structural fatigue and unexpected equipment failure. Condition monitoring programmes therefore rely on accurate vibration measurement to assess machinery health, identify developing faults and support predictive maintenance strategies that minimise downtime and operational cost.
For more than four decades, DJB Instruments has supported critical infrastructure and industrial monitoring applications, including long-term deployment within UK nuclear power generation facilities.
Monitoring critical rotating machinery
Industrial condition monitoring systems are used to assess the performance and integrity of key assets across power generation and manufacturing environments. Typical applications include:
- Bearings and rotating equipment monitoring
- Turbines, pumps and compressors
- Gearboxes and drive systems
- Structural vibration monitoring
- High-temperature industrial processes
Typical accelerometers and instrumentation used include:
- A/140 Series low-cost industrial accelerometers
- VS1 handheld vibration meter for spot measurements
- Custom-designed junction boxes
- A/81 and A/52 high-temperature accelerometers
High-temperature condition monitoring
DJB flange-mounted high-temperature industrial accelerometers, including the A/81 and A/52, have been successfully deployed in demanding power generation environments for over 40 years. Applications include gas circulators and other critical plant machinery operating under extreme thermal conditions.
These environments require robust sensor construction capable of maintaining signal integrity at elevated temperatures. Stainless steel mineral-insulated cables welded directly to the accelerometer body enable operation in environments reaching up to 800°C, ensuring reliable signal transmission to monitoring equipment.
Both the A/52 and A/81 incorporate DJB’s Konic Shear® design, providing long-term measurement stability while reducing cross-axis sensitivity. High-temperature piezoelectric sensing elements support continuous operation at temperatures up to 400°C.
