Level Switches and Sensors Products
About our Level Switches and Sensors Products
Applications Engineering is a renowned supplier of high quality level switches and sensors. These items are a vital component part of any process-controlled application where you need to determine either a single fluid level or multiple levels. As one of the UK’s leading suppliers of a huge range of these products, we can provide them to you in wide variety of materials (plastic, stainless steel, alloy) as well as for a wide variety of engineering applications.
Level sensors and switches have numerous float options or mounting options, and have various different electrical terminations also available. We also offer multi-station level switches which have the ability to monitor a number of different liquid levels within a tank if you require it. Applications Engineering also specialises in vertical and horizontal, marine industrial and pump control level switches, optical and solid state and much more. All of our level switches have been rigorously safety tested to ensure your peace of mind.
If you can’t find a switch that matches your requirements, we have the capability to custom design a level switch that will perfectly match the specifics of your engineering project. Alternatively you can talk to a member of our experienced team by getting in touch with us today. We will be happy to provide you with any advice and guidance you need.
What is a level switch?
Level switches, or float switches, are used to trigger an opening or closing mechanism depending on a certain level of fluid within a chamber. For example, a level switch may be used inside a boiler or cistern, to ascertain a suitable amount of water is present before allowing the valve to be activated.
How do level switches work?
While there are various styles of level switch, most function in a similar fashion. The fluid inside a container lifts an attached float (either internal or external), activating a mechanical action that completes a circuit. This might be a mercury switch on a hinge, or a buoyant rod that rises to trigger a microswitch.
Level switches can be used for continuous or point measurements, and are often used in sequence. For example, a set of sensors climbing the wall of a tank can be used to measure continuous fluid levels, and trigger set actions at each new depth. Inside a shower pump system, the “on” sensor may be significantly higher than the “off” point, so that the tank will not be excessively filled or drained.
