Panel Indicators, Pilot Lights

1.63018.0910000 application field and working principle

Panel indicators and pilot lights have gradually become an indispensable part of industrial control systems. They come in different shapes and sizes, but they all work together to control and indicate various operations. This article will discuss the application field of panel indicators and pilot lights and the working principles of each.

Application Field

Panel indicators and pilot lights are widely used in various control systems. Common applications include measuring, monitoring, and judging, communicating and controlling mechanical devices, and providing guidance in electrical system control. The traditional panel indicator was often referred to as a “traffic light” due to its three-light design indicating red, yellow, and green. This traditional design has been adapted for a diverse range of applications in industrial control systems.

For example, pilot lights are used in power plants to indicate when systems are in self-test or ready modes and to indicate when processes are blocked, vented, or completed. Panel indicators are also used in proximity control systems to indicate whether a signal in a process has been detected or not. In the manufacturing industry, panel indicators and pilot lights are used to indicate when something is off, on, out, or running.

Working Principle

Panel indicators and pilot lights produce a certain light intensity that can be seen from a distance. This light intensity is determined by the intensity of the current passing through the unit. The intensity is also changed by adjusting the control switch.

Panel indicators and pilot lights can also be wired to a combination of switches such as push buttons, momentary toggle switches, or rotary switches. This combination helps provide better control over the system by allowing different signals to be sent to the panel indicator or the pilot light. The combination also allows for multiple signals to be sent to multiple systems.

Panel indicators and pilot lights are also designed to withstand strenuous conditions. They are designed to be able to sustain temperatures ranging from -20°C to +60°C, as well as a pressure up to 16 bars. They are also designed to provide a long-lasting, reliable operation without the need for frequent maintenance.

Conclusion

Panel indicators and pilot lights are an integral part of industrial control systems. They are used in tasks such as measuring, monitoring, and judging, communicating and controlling mechanical devices, and providing guidance in electrical system control. Their design and construction allows them to withstand strenuous conditions and provide a long-lasting, reliable operation without the need for frequent maintenance.
