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.

A - 153: Fixed Differencial of variable height (one signal)
A - 153 - TDM: Fixed Differencial of variable height (two signals)
A - 153 - TDM - 3X: Fixed Differencial of variable height (three signals)
A - 103: Variable Differencial of variable height (one signal)
A - 103 - TDM: Variable Differencial of variable height (two signals)
A - 103 - TDM - 3X: Variable Differencial of variable height (three signals)
CHARACTERISTICS
The A Serial combines the displace operational system, with the safety of the magnetic assembly. Thischaracteristic makes possible to detect large liquid movement differentials, impossible with a floating one. It allows to operate with working conditions where it is required to detect fluids with a very low density of 0,45 kg/dm3 and high pressure.
It allows to detect liquid %u2013 liquid interface.
Pressure up to 250 atm.
Adding a dissipating extension it allows to operate with a temperature up to 280°C.
It is possible to have from one to three signals, it can be duplicate or triplicate whereever it is requiered.
