The basic function of current sensors is providing continuous quality power in order to prevent problems.
The sensor reacts to changes in input supply or in monitored current. Over current sensors protect from ground fault, mechanical jamming or other overload conditions. Relay output can reduce power to slow down a process and allow action to recover after time delay. Under current sensors sense lack of power, shut down a process and notify via warning signal, or allow restart after current is restored.

Current Sensors monitor fans in Industrial Drying applications

Drying powdercoated parts

Pharmaceutical drying machine

Industrial dryers, large or small, require the ventilation system to be working properly. If the fans do not come on within 5 seconds when the dryers operate, the Peltec 351 sends a signal to the main control panel to shut the dryers off and flash a warning light.

Current Sensors monitor power supply in UV Light Sterilization settings

Ultraviolet lab sterilization

Sterilizing medical instruments

Systems using ultraviolet light for sterilization of hospital rooms, medical devices and surgical tools require continuous power for expected performance. If the UV light goes out during operation, the Airotronics CS senses the lack of power and shuts the unit down. At the same time, it turns on a warning light and audible alarm.
