 Wireless vibration sensors are non‑invasive devices that can be mounted on plant equipment, such as pumps, motors, heat exchangers, compressors, couplings, and fans, to monitor and trend the health and performance of the equipment. The monitoring and trending data can then be used to identify degraded conditions that could lead to equipment failure. A wireless vibration sensor system includes the sensor hardware, the gateway/receiver for data transmission, and the interface processing software to integrate the data into the plant historian. The mounted vibration sensor is battery‑powered and measures velocity or acceleration of the monitored plant component and transmits the data to the gateway/receiver. The gateway/receiver then transmits the data either wirelessly or through a wired connection to the plant business network or specified computer for data integration. The data is then integrated into the plant historian using software either developed in‑house or purchased from a vendor depending on the utility’s historian configuration. The data can then be used for trending to assess the equipment performance to increase reliability and reduce maintenance costs. The wireless vibration sensors can be mounted using various methods, such as a stud, epoxy, or magnetic mounting. Choice of mounting is dependent on the application and site‑specific requirements.

==Description==
Wireless vibration sensors are non‑invasive devices that can be mounted on plant equipment, such as pumps, motors, heat exchangers, compressors, couplings, and fans, to monitor and trend the health and performance of the equipment. The monitoring and trending data can then be used to identify degraded conditions that could lead to equipment failure. A wireless vibration sensor system includes the sensor hardware, the gateway/receiver for data transmission, and the interface processing software to integrate the data into the plant historian. The mounted vibration sensor is battery‑powered and measures velocity or acceleration of the monitored plant component and transmits the data to the gateway/receiver. The gateway/receiver then transmits the data either wirelessly or through a wired connection to the plant business network or specified computer for data integration. The data is then integrated into the plant historian using software either developed in‑house or purchased from a vendor depending on the utility’s historian configuration. The data can then be used for trending to assess the equipment performance to increase reliability and reduce maintenance costs. The wireless vibration sensors can be mounted using various methods, such as a stud, epoxy, or magnetic mounting. Choice of mounting is dependent on the application and site‑specific requirements.

Several other MTAs for continuous online monitoring describe applications for wireless vibration sensors, such as MTA-MA-002 (motors), MTA-MA-008 (heat exchangers), MTA-MA-009 (pumps), MTA-MA-010 (compressors), MTA-MA-011 (couplings), and MTA-MA-014 (fans).

==Benefits==
===Benefits Estimate===
Level 1 – Savings are less than $1 million per year, however, cost savings could be significantly greater if vibration monitoring helps avoid equipment failures.
===Benefits Description===
* Increased equipment reliability because adverse equipment performance trends and degradation can be identified early.
* Reduction in labor hours associated with traditional trending and monitoring by integrating data into the plant historian.
* Reduced installation cost for wireless sensors compared to wired instrumentation, which can exceed $1M to implement due to cable routing.
* Reduction in maintenance costs by supporting the transition from time‑based monitoring to condition‑based monitoring.
* Reduction in personnel dose by enabling the replacement of in‑person, manual monitoring of equipment in high‑dose areas with automated monitoring.

==Costs and Schedule==
===Cost===
Level 3 – Implementation cost is less than $1 million and includes engineering, installation, and development of the software to integrate the data with the plant historian.
===Schedule===
One to three years for engineering, installation, and development of software in‑house. Schedule can be reduced to less than six months should the utility purchase software from a vendor.
===Scope Context===
Per site.

==Risks==
The system must be properly segmented and implemented to avoid an increase in vulnerability to cybersecurity threats. Following the cybersecurity guidance in the available reference implementation guidance will mitigate this risk. Alternatively, the sensors could be used for monitoring only and not for operational decision making.

Electromagnetic Compatibility (EMC) must be considered to ensure that the wireless signals from vibration sensors do not adversely affect nearby equipment. Following the EPRI and U.S. NRC guidance for equipment EMC qualification and maintaining a minimum separation distance, if required, will mitigate this risk.
