Reed switches in Coolant flow sensing
A coolant is a fluid, that is used to reduce or regulate the temperature of a system, like an engine through a radiator, or for example, the passenger space by means of an air conditioner. In any of these systems, it is important that the continuous flow of coolant flow be monitored. This is achieved with flow switches mounted to and from the area that require cooling. This helps check that the input to the system has not reduced, and that the output from the system has the same rated % drop. A simple, cost effective reed switch based flow switch. Reed Switch based flow switches are available in different configurations, either normally open or normally closed, to close or open at a wide range of flows. This helps circuit designers be flexible with regards product selection. As long as the coolant is flowing at the required rate, the flow switch can either signal the controller. by chance, there is a block or if the coolant valve malfunctions, an indication is given on the instrument panel.
Applications are classified as Position Sensing, Pulse Counting, Electromagnetic or Relay, Temperature Sensing or Magnet Biasing types. This application is classified as follows and the link gives more information on best practices to help select the most suitable AT band and matching magnet.
The Reed Switches and Sensors used in such applications need to be robust, durable and efficient in meeting a high life expectancy. Our engineers work hard in life testing our products under various conditions, and our intention is to ensure end product durability and life. Although we wouldn’t want to restrict any of our products for use in only certain applications, the recommended products for use in this application are listed below.
