Industrial liquid level sensor: 3 different applications
The difference between a liquid level sensor for wastewater, one for corrosive materials and one for conductivity is self-evident and determined by the chemical-physical characteristics of the liquid in question. Think of the viscosity of honey and how much it makes it move slower than water in uniformly taking the form of the container.
What is less obvious is to determine the best level indicator based on the industrial plant. The processing of plastics, waste recovery, the food industry, the production of pet food and of synthetic textile fibers, mostly made from a liquid obtained from coal, oil or natural gas, require a certain experience in choosing the level probe.
For almost 30 years CAMLogic has been suggesting, designing and developing the most suitable detection instruments for liquids. Let’s see 3 examples.
For corrosive liquids
Where there is a demand for single level control, minimum or maximum, inside a cistern or tank, the float-based PFGLP22 is used. It is a liquid level sensor ATEX certified and suitable in the presence of aggressive and corrosive substances, such as in the case of Nuova Ciba plant, where the float with flange connection measures the presence of oils and liquid components for rubber.
The sensor PFGLP22 operates according to Archimedes principle and, thanks to an internal magnet, activates a microswitch. To facilitate optimal operation, in which the float is parallel to the surface of the liquid, the model is also available with a curved stabilizer stem.
For foaming liquids
Another float-based indicator is the new CLR20, a water and liquid level sensor recently developed featuring a permanent magnet, frictionless reed switches, spherical float and autonomous power supply. It is a real novelty in the CAMLogic range that offers more measurement precision and control in the presence of foam.
It is, in fact, possible to implement three floats in a single instrument to control three liquid levels (usually minimum, midpoint and maximum). Given its small size it can be installed in smaller containers as well, in addition to cisterns or silos.
For conductive liquids
The conductivity of liquids is another necessary to consider when choosing the most suitable instrumentation. To solve any false detections, CAMLogic implemented in the CLC40 level indicator a signal delay.
The sensor is also suitable for minimum conductivity values (5μS/cm) and when used with three electrodes in filling pumps, it allows the signaling of minimum and maximum levels. When used with two electrodes only allows for their activation or deactivation.
Which choose CAMlogic liquid and water level sensors?
CAMLogic level indicators have all parts in contact with the product in stainless steel, suitable for installation in food or chemical plants. As the examples show, they are also used in wastewater treatment and therefore where liquids with solid residues must be detected.
As we saw, in the control of liquids several variables must be considered. Finding simple and reliable solutions that allow you to obtain the optimal result expected from the application is extremely important. Discover the CAMLogic liquid range.
