LEVEL SWITCHES
The Level Switches Serial A, has six especific models according to service conditions:
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.
USE
- Tanks of Reception for Natural Gas
- Tanks of Storage Hydrocarbon
- Tanks of Condensed

Particularly reservoirs located under floor level or in pits need for the visual surveillance of the liquid level devices that can be installed on top of the tank. The NS-OM range provides a visual indicator directly coupled to a float inside the tank. In addition to the optical indication, electrical signals are available. These come, depending on the version, either from internally or externally located contacts or continuously operating analogue displacers.

Comus International has now added to their extensive range of switch and sensor products a range of vertical and horizontal plastic and stainless steel floats.
The range includes vertical and horizontal mounted single and multi float types including the side mounted crocodile type.
The float switches are compact, reliable and very easy to install. They are not affected by electrical interference and with a wide range of materials are able to withstand various chemicals, high temperatures and high pressures. By varying the size of float and material used we are able to make sure the switch activities correctly every time.
The activation of the switch uses the principle of a reed switch and magnet.
When used in the vertical position the reed inside the stem is stationary and the float (housing a magnet) is moved up or down passed the reed switch (this closes the reed contact). When the magnetic field is moved away the reed switch opens.
When used in a horizontal position the float is used in a pivotal movement. The magnetic field inside the float is moved into the proximity of the reed switch inside the stationary stem. The reed switch opens or closes.
For more technical information on these and over 800 switch and sensor products please contact the sales office.

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.
