WHITE-LIGHT

White-Light is one of the most widely used wavelengths of light and is something we’re all used to seeing and using in day-to-day life. One of the main advantages of using White-Light as part of a security system is its ability to provide colour images (providing it’s being used with a colour camera). Being able to positively identify the colour of someone’s clothes, hair, or other features, could provide crucial evidence for prosecution. The defining characteristic of White-Light illumination is that it is highly visible to the human eye, hence it’s use for general area illumination. For surveillance applications, this is also useful when using White-Light as a deterrent to ward off potential intruders. On the contrary, if covert surveillance is the aim, White-Light illumination is unlikely to be the answer.

Using constant White-Light at night may not be suitable for all applications, due to the fact that the target area is lit up, and therefore, potentially assisting an intruder in undertaking a crime. When using White-Light, consideration also needs to be given towards light pollution. While the use of LED technology means the light can targeted accurately, some applications may be restricted in their ability to use White-Light for environmental reasons such as protecting the night sky or wildlife.

How to Wire, Test and Install a Pressure Switch

Pressure switches are commonly used across many aerospace, defense, and industrial applications to provide systems with an on or off capability–either towards the rise or fall of pressurized fluids. Understanding how to properly manage and control these switches can be helpful when choosing a solution for a given operation. The following guide will cover best practices and steps for troubleshooting the latest pressure switch designs.

How To Wire A Pressure Switch

The model shows our 6900GE and 6900PE aluminum-gage pressure switches, made specifically for hazardous environments. Switches are often used as a primary mode for opening and closing an electrical circuit. The wiring can change from single make and break circuits to multi-makes and break circuits. While the mechanics are pretty straightforward, the proper circuit must be chosen for the right application. Let’s take a closer look at each circuit style and how it can be used in a system.
