Panel Indicators, Pilot Lights

1.69507.1571002 application field and working principle are two widely used tools in the automation industry. Panel Indicators and Pilot Lights are generally used for status indication of industrial equipments and processes. In order to understand the application field and working principle of these tools, an overview of the general functioning, features and benefits of these tools will help to further explain their utility.

Panel Indicators

Panel Indicators, also known as annunciators, are a type of illuminated signal light that is usually found on a control panel in industrial systems. These devices provide a quick visual indication of any change or fault in the system, and this makes them ideal for process monitoring and control applications. Panel indicators are available in a variety of forms including LEDs, fluorescent and incandescent bulbs, as well as a combination of these technologies.

Panel indicators typically have a multi-color display which helps in proper reporting of the status. The most commonly used colors are red, green and amber, but other colors such as yellow and blue may also be used. The multi-color display of panel indicators allows the lighting to indicate different states such as status OK or error state. This helps operators to quickly identify any potential problem within the system.

Panel indicators are easy to install and maintain, and they provide reliable and long-term illumination. They are usually designed to work in dusty or dusty environments and are typically rated for an operating temperature range between -20 to +70°C.

Pilot Lights

Pilot Lights, also known as lamp indicators, are another type of illumination device commonly used in automation applications. These simple illumination indicators are typically used to provide a visual indication for the status of processes or machine operations. Pilot lights are usually cylindrical metal tubes protected by either glass or plastic, which includes color-coded LEDs or incandescent light bulbs.

The color-coding of the pilot light helps to identify the status of operations. For example, a red light may indicate a fault, amber may indicate a warning, and green may indicate normal operation. Unlike panel Indicators, Pilot lights are usually not adjustable, as they are designed to be specifically used for non-changing or non-adjustable status indications.

Pilot lights are also easy to install and maintain, but they are typically designed to work in less hostile environments than panel indicators. These devices are usually rated for an operating temperature range between 0°C to +50°C. Moreover, they tend to consume lower power than panel indicators, and therefore, they are ideal for applications where power consumption is an issue.

Conclusion

Panel Indicators and Pilot Lights are two widely used illumination devices in the automation industry. They are often used to provide a visual indication of any fault or change in the system and are ideal for process monitoring and control applications. Panel Indicators come with a multi-color display which makes it easy to identify any potential problem, while Pilot Lights are usually color-coded to provide quick status indication.

Panel indicators are usually designed to work in hostile environments, while pilot lights are better suited for less hostile settings. Both devices are easy to install and maintain, butpanel indicators typically consume more power than pilot lights, making them more suitable for applications where power consumption is a concern.
