High-resolution displacement sensing technology promises improved machine health insights and reduced downtime across demanding environments.
A new family of non-contact displacement sensors by the Measuring Division of Kaman Precision Products, Inc., is gaining attention for its ability to deliver high-precision measurements in harsh industrial settings, including high-pressure environments reaching up to 40,000 psi. Designed for condition monitoring, the sensors provide a resolution of 1 micron RMS, enabling accurate tracking of machine performance and early detection of potential faults.
The key features:
- Non-contact displacement sensing with up to 1 micron RMS resolution
- Operates in high-pressure environments from 500 psi to 40,000 psi
- Supports vibration, speed, and runout monitoring for condition analysis
- Multiple output formats for easy system integration
- Rugged IP67 design with customizable configurations for OEM use
The technology focuses on improving how industries monitor critical parameters such as shaft runout, rotational speed, and vibration patterns. By capturing subtle changes in machine behaviour, the sensors help identify issues before they escalate into costly failures or unplanned shutdowns. This is particularly relevant for sectors where continuous operation and equipment reliability are essential.
A key differentiator is the non-contact measurement approach, which eliminates physical wear between sensor and target. This not only extends operational life but also ensures consistent accuracy over time, even in challenging environments. The sensors are also adaptable for a wide range of applications, including gear condition monitoring, surface thickness inspection, and detection of cracks or material defects.
Flexibility in integration is another notable aspect. Multiple output options—such as voltage and current signals—allow compatibility with existing industrial control systems. Additionally, the sensors can be customized for OEM requirements, making them suitable for diverse machinery and system designs.
Built for durability, the devices feature IP67-rated protection and are available in various configurations, including threaded, flanged, and pressure-port-compatible designs. This rugged construction supports deployment in environments exposed to contaminants, moisture, and extreme mechanical stress.
As predictive maintenance and smart monitoring continue to shape industrial operations, such high-precision sensing solutions are becoming increasingly critical in improving efficiency, safety, and equipment longevity.
