subject: Some Tips In Choosing Liquid Level Sensors [print this page] Particularly in industries that involve processing of liquid products, a liquid level sensor plays a very important contribution to make the process more accurate and efficient. This device is used to detect the level of liquid in a process tank.
If you are working in a semiconductor company -- or any high tech manufacturing environments -- looking for liquid level sensor products to use, there are a number of considerations that you need to take into account prior to purchasing:
(1) the device must be capable to withstand various types of chemistries;
(2) your prospect must be a reliable source of liquid level sensor products that do not pose a risk of contamination;
(3) can do its function even when exposed to high process temperatures.
Different types of Liquid Level Sensor to choose from:
-Elixir Liquid Level Sensor--one option that might want to know is elixir sensor. It is a tuning fork-based level sensor for liquids and the system includes keeping mechanical vibration at resonance frequency. When the tines of the fork are immersed in liquid, changes in the frequency are sensed electronically and processed signal is utilized for switching.
-K11 Liquid Level Sensor--this product is designed ideally for high pressure applications (e.g. pressurized vessels, HVAC and refrigeration, motors, and more. An infrared technology is employed in this product.
-SLW water level indicator-- this device is utilized primarily for pump switch on and off preventing dry running of pumps and overflow of service material in the process plants.
-MEDER LS-Series Liquid Level Sensor -- this device is said to be more reliable than mechanical switches and is considered as an alternative to costly Hall Effect sensor. This particular unit is designed so that it is made out corrosion-resistant materials. It uses magnetic floats feature that will activate reed switches when the liquid level rises or falls. It does not need external power to function.
