Emerson vibration sensor simplifies asset monitoring


The AMS Wireless Vibration Monitor from Emerson is a low-cost, easy-to-deploy vibration sensor that performs prescriptive analytics on vibration data using native software to automatically identify failure modes and prevent potential problems involving rotating assets. The compact device makes it economically feasible to fully monitor motors, pumps, fans and other critical plant equipment to reduce downtime and achieve more reliable operations.

Vibration in rotating machinery can signal issues such as misalignment, gear defects, insufficient lubrication, pump cavitation and rolling element bearing defects – all of which can be precursors to hazardous conditions. Vibration analysis is therefore one of the most important techniques for monitoring the condition of such machines as part of a predictive maintenance programme.

The continuous collection of vibration data enables potential problems to be identified earlier, thereby preventing unexpected failures that can cause safety incidents and production loss. However, cabling and equipment costs can prohibit continuous, hard-wired online vibration monitoring. In these cases, organisations have typically substituted manual measurements taken via handheld units, but the analysis of manual readings can require time and expertise. Wireless monitoring technology removes the need for expensive cabling but many organisations do not have personnel with the necessary ability to correctly interpret the often-complex vibration data that is made available.

Generating actionable data

The AMS Wireless Vibration Monitor provides a solution by collecting and contextualising vibration data to generate actionable information. By applying Emerson’s patented PeakVue™ Plus technology, the device not only identifies when and how assets will fail, but also why. PeakVue Plus builds on proven PeakVue technology that filters vibration signals to focus on impacting, a leading indicator of overall asset health on any type of rolling element bearing machine. Thanks to this embedded intelligence, plant managers can add wireless vibration monitoring to their maintenance toolbox without having to train current staff to perform complex analysis. Instead, technicians, regardless of expertise, can quickly and clearly identify and prioritise mechanical issues, enabling them to focus more on operations-critical tasks.

The AMS Wireless Vibration Monitor can be preconfigured or configured onsite using a wireless gateway or handheld device, enabling organisations to place the device at any location in a facility immediately without needing to install and connect separate sensors to the transmitter. This gives almost instant access to readings and complete visibility of the health of that equipment. In addition, a longer battery life and field-replaceable batteries means users can plan for less maintenance and fewer trips to the asset being monitored. All these capabilities mean faster deployment, less engineering, and quicker return on investment.

The AMS Wireless Vibration Monitor operates on a plant’s existing WirelessHART® network and fully supports the vibration analysis tools included in Emerson’s AMS Machine Works software. It uses a triaxial sensor to capture data in three dimensions to generate a complete picture of the machine condition. The AMS Wireless Vibration Monitor is the latest addition to Emerson’s comprehensive health monitoring portfolio, which includes the AMS Asset Monitor and AMS 6500 ATG. Together, these devices help organisations fully monitor the health of machinery equipment, from essential assets to operations-critical assets that can have immediate impact on safety and production.
