Bulletin 840 Automatic Float Switches are heavy duty horsepower or control circuit rated devices which can be used to control and monitor liquid levels in a tank or sump. As the liquid level rises or falls in a sump or tank, at a preset level the switch can either start a motor to adjust the liquid level or activate a circuit to turn on a light or sound an alarm. Bulletin 840 Float Switches are designed for long life and heavy duty operation. They are offered in five different styles with many different float operator assemblies.
Bulletin 840 Automatic Float Switches:
Liquid Level Sensitivity From 2 to 5 Inches
0.6 to 3.8 lbs Switch Operating Force
2 or 3 Pole Contact Configurations
Tank to Sump Convertibility
NEMA A600 and NEMA N300 Contact Ratings
Type 1, Type 4, and Type 7 & 9 Enclosures

LIDEC level switches: a dependable solution for liquids detection
Developed in cooperation with “Paris VI” University, the Lidec series liquid level sensors series are especially designed for marine applications.
They provide a reliable solution to liquid level detection.
Their operating principle, a patent granted to Enraf Marine Systems, is based on the propagation of a surface wave inside a stainless steel probe.
This principle is fully static, without vibration or moving parts. A "self-monitoring" function ensures the reliability of this equipment. This allows these sensors to be used in safety systems such as overfill protection, bilge well alarm and water ingress detection...

Bernstein designs and manufactures a modular system of float switches which can be combined and configured to create a switch that ideally meets customer specifications.
Float switches provide a reliable and cost-effective acquisition of level information in containers with stagnant or flowing liquids, such as water, oils, alkaline solutions and similar substances.
A float switch comprises a connector element, a switching tube with 1 to 4 reed contacts and the float. The float is equipped with an integrated ring magnet and rises and falls with the level of the fluid. The magnetised contact reeds trigger a signal as soon as the float reaches the sensing range of the reed contact.
The range of Bernstein float switches ranges from miniature versions to heavy-duty and pressure-resistant versions.
The particular advantage of these float switches is, that the switching contact can directly – when furnished with the proper protection – switch loads, e. g. relays, signal lamps or even small pumps.

LL SERIES REFRIGERANT FLOAT SWITCHES
This float controlled, magnetically actuated, mechanically operated, HERMETICALLY SEALED switch assembly can maintain close control of liquid level. The rugged construction makes it relatively insensitive to disturbances of the refrigeration system or vibration of the attached pipelines. The electrical switch, which is fused, and the operating mechanism are encapsulated within a transparent housing, which HERMETICALLY SEALS the moving parts and switch from ambient conditions and yet allows observation of the switching motion for determination of the liquid level. Type LLC, LLSC, LLAC are U.L. Listed for outdoor service. Types LLX, LLXS, or LLAX are not fused.
