Abstract

Things to consider when integrating infrared sensors into systems include mounting and protecting the sensors properly and interfacing them to the rest of the system. Some of the considerations to be discussed apply to any sensor, and some are unique to infrared sensors. Mounting considerations include protection from atmospheric contamination and high ambient temperatures. The field of view and the background must be controlled. There are various ways of connecting infrared radiometers to systems, including current loop, voltage output, and digital interfaces. The sensors might be connected to various components, including displays, data acquisition systems, and controllers. One of the considerations in interfacing these sensors is electrical noise. It is also necessary to avoid ground loops which may adversely affect accuracy. Signals must be properly scaled between components, and conversion resolution allowed for. Issues such as speed and accuracy must be considered from the point of view of not just the sensor, but also the overall system.
