Point level switches are often used as a warning indicator to trigger an alert when a fluid level is either too high or too low within a tank or vessel. A single point level switch detects if a predetermined single liquid level is reached and actuates a switch to notify a user. Single point level switches are available in multiple sensing technologies including float, electro-optic, ultrasonic, capacitive, and water in fuel.
Types of Single Point Level Switches

Capacitive Single Point Level Switches
Gems Capacitance sensors are frequency-tuned for liquid detection. Most are noncontact models that sense from outside a fluid vessel's wall and offer adjustability to operate accurately with both aqueous and non-aqueous liquids.

Float Single Point Level Switches
A float level sensor contains a float magnet that travels freely along a stem as the level of liquid rises or falls, and a switch is activated based on the magnetic field that is generated.

Electro-Optic Single Point Level Switches
Electro-optic liquid level sensors feature a small footprint for anywhere space is at a premium. Solid-state switching delivers dependability over a long service life.

Ultrasonic Single Point Level Switches
Ultrasonic switches are non-contact and work by emitting high frequencies that are reflected back and measured. Gems ultrasonic switches and transmitters are ideal for applications requiring solid-state level measurement, such as those with ultrapure, dirty, coating, scaling, or corrosive-type liquids.
