Panel Indicators, Pilot Lights

Panel indicators, pilot lights are used in a wide range of industrial applications. They provide an audible, visual, or tactile warning signal to operators when a hazardous condition is present. Indicators are typically used to alert operators when hazardous conditions exist, such as when the power supply has been lost or when operations are about to begin. Pilot lights are often used to indicate the status of a process or machine.

Application Field

Panel indicators and pilot lights are used in industrial control, process control, and safety applications. They can be used to alert operators of potential hazards, a change in the process, or the need for maintenance. Additionally, they can be used to indicate the status of a process, such as the presence of an alarm or off-normal condition. In addition to detecting and indicating dangerous conditions, these components provide an additional functional safety feature in the form of a visual warning or alarm signal.

Working Principle

The way that panel indicators and pilot lights work depends on the type of light. Panel indicators can be mechanical, such as an illuminated switch or a pressure-sensitive switch. Pilot lights may consist of an illuminated switch, incandescent light bulb, LED, or an array of LEDs. The most commonly used light is an LED, as it provides a bright, long-lasting light while using very little power.

When a hazardous condition exists, a panel indicator will emit an alarm or warning signal to alert operators. This warning signal is usually visible via a bright, flashing light on the front of the indicator, which will typically be placed in a prominent area for maximum visibility. Pilot lights, on the other hand, are used to detect and indicate the status of a process or machine. These lights will be typically lit if the process or machine is in operation or will be dark if the process or machine is stopped or off-normal. The intensity of the light can also be used to indicate different levels of process alarms or power levels.

Panel indicators and pilot lights are very effective tools for quickly detecting and indicating hazardous conditions, as well as the status of a process or machine. They provide a powerful, visual warning signal that operators can use to safely and efficiently operate their equipment.
