Liquid Level Switches (How It Works)
Liquid level switches from TE Connectivity are rugged and reliable solutions for industrial liquid level monitoring. Available in multiple configurations including vertical mount and side mount up to 90° angle.
TE Connectivity (TE) offers liquid level sensors with reed switch reliability in numerous standard and custom configurations. Our single point fluid level switches can be arranged to have the switching element "close" or "open" when the level decreases. Switch orientation options include horizontal and vertical (top or bottom entry), depending upon the configuration chosen. All of our housings have at least IP-65 enclosure rating and both external and internal fit liquid level switches are available.
Materials used on our liquid level sensors include:
Silicone sealing materials are standard with Nitrile and EPDM (Flourorubber is also available)
The following are the key benefits of using a reed switch/magnetic float level sensor:
Liquid level switches from TE Connectivity are rugged and reliable solutions for industrial liquid level monitoring. Available in multiple configurations including vertical mount and side mount up to 90° angle.
Liquid level switches from TE Connectivity use reed switch technology delivering an extended product life of 10M+ cycles, high electrical load capacity, low contact resistance, and UL approvals. Our liquid level switches are offered in a wide range of standard and custom options.
