What are common use cases for using a voltage sensor in predictive maintenance?

Voltage sensors alert your maintenance team of potential problems related to any device emitting electricity. These wireless sensors can be placed on a wide variety of equipment including devices, other sensors, or batteries. Data is then relayed back to a central location where a maintenance manager can make predictive maintenance decisions after analyzing this data. Here are some common usages for voltage sensors.

AC Voltage Sensors

Sensors that measure AC voltage levels can be used in a wide variety of applications including:

  1. Power demand control. Monitoring voltage levels can help ensure a steady supply of power when it is needed.
  2. Power failure detection. A power failure can create significant downtime losses, and immediate notification can help minimize larger problems.
  3. Load sensing. In any piece of hydraulic equipment, voltage sensors can help detect problems with pump functioning.
  4. Safety switching. If you have a faulty wire or other electrical issue, you’ll trip the safety switching system to prevent electrical shock. Voltage sensors can provide 24/7 monitoring.
  5. Motor overload control. The last thing you want is an overloaded motor. Voltage sensors can detect an excessive current draw and notify you before an overload results in damage.

DC Voltage Sensors

Those sensors that are designed to monitor DC voltage levels are typically used in:

  1. Energy management control systems. Voltage sensors can help optimize an energy generation and transmission system with a facility.
  2. Building control systems. The mechanical and electric systems within a building must run smoothly every day. Voltage sensors can be placed on key components to signal any potential issues.
  3. Fault detection. Voltage sensors can steer facility management to potential faults before they become major problems.
  4. Data acquisition. Gathering data is critical to a good predictive maintenance program, and voltage sensors can ensure that data is accurately collected.
  5. Temperature control. Although temperature sensors are available, voltage sensors check the voltage being emitted from these temperature control systems, which can signify an issue that requires maintenance.

Specialized Sensors

In addition to AC and DC voltage detectors, you can use specialized ones in the cases of high-voltage requirements. Many of the latest developments in voltage sensors employ fiber optic components.
