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

Float Single Point Level Switches

Electro-Optic Single Point Level Switches

SP - Electro-Optic
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.

Electro-Optic Single Point Level Switch Products:

Ultrasonic Single Point Level Switches

SP - Ultrasonic
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.

Capacitive Single Point Level Switches

SP - Capacitive
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.
