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.

Continuous Level measurement
The external mounting and the non intrusive arrangement of a continuous level measurement are some of the outstanding advantages, that determine it for various applications like:
high- and low-pressure reactors
agitated vessels
bunkers
autoclaves
hot material industrial containers, etc.
No matter, what the physical- and chemical properties of the measured product are nor what the shape of the vessel is.

High frequency microwave impulses are coupled to a cable or rod and guided along the probe. The impulses are reflected by the product surface and received by the processing electronics.
Due to this measuring principle, the comprehensive adjustment with the product is no longer necessary. The instruments are adjusted to the ordered industrial electrode length. The shortable cable and rod versions are suitable for individual adaptation to the local conditions.
Even process conditions such as high dust and noise generation or strong steamy atmospheres do not influence the accuracy of the measurement.
Density fluctuations, different granulation or even fluidising do not influence the accuracy. This applies also to the change from dry to wet gravel.
Strong build-up on the electrode or on the vessel wall does not affect the measuring result.
With measuring ranges up to 30 m, the sensors are also suitable for high vessels. Temperatures up to 150°C and pressures from vacuum up to 40 bar cover a wide application range.
By using a coaxial guide tube, VEGAFLEX 65 operates completely unaffected by vessel installations such as e.g. heating spirals or struts. A special adjustment is not necessary. |

"Nivotemp 63 K + KN, 63 K-VA + KN-VA
Modern production facilities employ more and more plant automation systems and computerized controls. These allow the monitoring and control of hydraulic and lubricating systems. Traditional level controls are focused on pump protection i. e. a typical system is equipped with a level switching with one or two contacts. These contacts protect the pump from running dry in the event of leakage..
Modern systems provide the opportunity for a pro-active leakage control by the use of continuous signals.
An analog output of 4-20 mA signals continuous signals the fluid level. Deviations from the ""normal"" are detected instantly and can be transformed into many types of action. In case of a catastrophic failure such as a burst hose the pump could be shut down immediately rather then let it run until the traditional switch turns it off after a large volume of oil has spilt.
The Nivotemp 63 versions provide continuous analog signals for liquid level only or for level and temperature combined. They are available in two standard length or in 150mm increments. The flange dimensions are the standard ones used for filler/breathers ( DIN 24557/2). In addition the units can be combined with our Fluidcontrolterminal which makes oil care even more technically advanced.
The 63..VA versions are suitable for use with high water based liquids ( HFA).

| The capcitive filling level systems operate according to the three-industrial electrode principle. With this principle the container or an additional electrode serve as a counter-electrode to the probe electrodes. For this reason it is necessary with this system that the container is of a conductive material or a "substitute electrode" is fixed to the container wall, e.g. copper foil. These systems are available with probes for analogue filling level metering of for detection of 1, 2 or 3 measuring points. The position of the switching points and the analogue measuring area is user-definable within the possible effective range and therefore it can be determined for optimal matching of each application. Level measurements of bulk material, liquids or pastes are possible with a dielectric constant as of εr 1,1. |

Extremely short microwave impulses with low emitted power in the C-band and K-band frequency range are emitted by the antenna system to the measured product, reflected by the product surface and received again by the antenna system. They spread with light velocity and the time from the emission to receipt of the signals is proportional to the level in the vessel. A special time spreading procedure enables a reliable and precise measurement of extremely short time periods.
By simply entering the vessel dimensions, a level-proportional signal can be displayed. An adjustment with emptied and filled vessel is no longer necessary!
The spreading of microwaves is virtually not affected by the ambient temperature and ambient pressure. Radar sensors are ideal for use under arduous process conditions. Pressures from vacuum to 160 bar and temperatures between -40 and 400°C are no problem for a radar level measurement.
Fluctuating product compositions or complete changes of the product do not influence the measurement result. A new adjustment is not necessary. |
