Level Switches, Float Switches & Sensors
About our Level Switches, Float Switches & Sensors
Offering a full range of level switches, float switches and sensors, Applications Engineering is one of the UK’s most renowned suppliers. Level switches and sensors are vital component parts of any process-controlled application that requires the ability to determine a single or multiple fluid 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 including plastic, stainless steel and alloy, as well as for a wide variety of engineering applications.
There are a wide range of float or mounting options, as well as various different electrical terminations available. We additionally offer multi-station switches – these have the ability to monitor a number of different liquid levels within a tank, if required. Applications Engineering also specialises in vertical level switches, horizontal level switches, marine industrial and pump control level switches, optical and solid state and much more. Our products are rigorously safety tested to ensure your peace of mind.
Can’t find the switch that matches your requirements? We can custom design any switch that be matched perfectly to the specific requirements of your engineering project. Alternatively, you can contact our friendly team and will be able to provide you with advice and guidance.
Frequently Asked Questions
- What is a level switch?
-
Known as level switches or float switches – these are used to trigger the opening or closing mechanism depending on the level of fluid within a chamber. As an example; inside a boiler or a cistern, level switches are used to understand when a suitable amount of water is present in order to activate the valve.
- How do level switches work?
-
There are various styles of switches, but the majority function in a similar way. The liquid 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 (float 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.
- Where are level switches used?
-
Level switches are used in a variety of scenarios including pumps, indicators, alarms, fuel tanks, water storage, and more.
