New level switches from Gems is ideal for high volume OEM applications

The LS-3 series level switches use a proven method of construction, with a magnet-equipped float, which is in direct contact with the surface of the liquid being monitored, actuating a hermetically sealed reed switch mounted within the stem of the device. This provides instant and precise measurement of liquid level. In common with all Gems buoyancy type level switches, contact between the fluid and the switch is fully isolated and sealed, ensuring a long and trouble-free operating life.

LS-3 Series level switches are available in a wide variety of engineered plastics, including polysulfone, polypropylene, and FDA-approved PVDF. These materials offer broad water-based, chemical, oil, and food grade compatibility in many different applications and enable volume unit costs to be minimised for OEMs.

The new switches can be operated with either end up, feature a unique fluted stem, to prevent a build-up of dissolved solids, can withstand temperatures ranging from -40ºC to +121ºC, and be used in systems operating at pressures up to 10.3bar. Each unit measures just 2.2cm in diameter and less than 5.0cm in length, is quick and simple to install and is virtually maintenance free. Mounting options include 3/8”-16 straight thread, 1/8” NPT, G1/8”, and M12x1.75 straight thread; switch actuation can easily be changed from N.O. to N.C. simply by reversing the float position on the stem.
LS-3 switches are also available in other unique configurations for special applications, such as low liquid levels and turbulent fluids, and are approved to UL Recognition, CE, CSA and FDA. This makes the LS-3 one of the most versatile low cost level switches available, backed up by Gems Sensors’ comprehensive European technical and sales support.
