Introduction
Voltage sensors are small, wireless devices that may be connected to a wide range of machinery, and equipment. When the voltage is too high, it can put other things in jeopardy, but when the voltage is too low, it can put other things in danger. When certain thresholds are reached, warnings are delivered to a central system.
Voltage sensors are low-cost equipment that can help you improve your preventive maintenance program significantly. Sensors may give a lot of data for your industry when used. Your maintenance management team may use this data to make strategic choices regarding repairs, investments, and process improvements.

Applications of Voltage Sensor
Fault Detection
They can be used to locate a specific fault in a piece of equipment or an entire system.
Safety Switching
Faulty cables might put you in danger of electric shock. Voltage sensors can be linked to a safety switching system that will shut down or reroute the voltage automatically. An alarm can also be generated to indicate the broken cables.
