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.

Water in Fuel Single Point Level Switches



SP - WIF
Water in Fuel switches are designed to detect the presence of water in fuel tanks and filters. It is a solid-state no moving parts sensor that is suited for off-highway vehicles, locomotives, and generator sets.
