  • Capacitance Level Sensors Uncovered

    Capacitance level sensors, also called RF or radio frequency sensors, are sensors that detect the level of a liquid or substance based on the differences between the frequency the sensor emits with the amount of AC circuit current the sensor receives back from the material inside the container. The differences in the two frequencies can identify the level of the liquid or material inside the container. Capacitance level sensors are highly useful in measuring the level of critical materials, such as when a liquid has a chance of overflowing or...

  • Level Sensors: Innovations and Improvments

    Manufacturers who utilize level sensors most often take extra measures to ensure there are no unwanted contaminants or particles introduced into their processes. One interesting innovation to help keep out these undesirable substances is a threadless level sensor. This product is designed to tighten from the outside a tank or pump and is capable of track liquid levels with an accuracy of /- 1 mm. A similar innovation is ideal for applications where zero substance contact is preferred. This product can monitor levels from outside the walls of the container...

  • Breaking Records with Level Sensors

    Capacitance level sensors have been around for a while, and are usually used to monitor the amount of liquid or material inside containers in a factory. Other uses for the sensors expand to the automotive industry, where capacitance level sensors help monitor the amount of fuel inside vehicle tanks. Although a level sensor is not the most glamorous piece of equipment ever, the sensors were able to help make history in July, 2012. One summer day in July, 2012, UAV Factory was able to break the record for the longest...

Industry Information

Level Sensor

Level sensors, also known as level indicators, are measurement devices used to determine the level of materials such as liquids, powders, slurries and granular materials. All of these substances have flow, meaning that within containers, they naturally flow to become level due to the effect of gravity.

While they are typically only used to measure materials that flow, level sensors may rarely be used for the measurement of levels for bulk solids. Since maintaining proper levels of materials is essential in many applications, level sensors are often used in industries such as pharmaceutical products production and distribution, for measurement indication of medical ingredients; HVAC, in order to monitor and control the oil or refrigerant level in heating and cooling systems; food and beverage, for monitoring of liquid and powder food items during handling, packaging and processing; industrial manufacturing, to control the levels of potentially hazardous chemicals required in various processing applications; and commercial, for monitoring of liquid levels in many restaurants, office buildings and more. However, different applications require different types of level sensors and the various criteria that should be used to determine what type of level sensor will be best-suited for a certain application includes temperature, material phase, density, container size and chemistry.

Level sensors typically include a switching mechanism, a tube and a couple of areas of connection. However, the design of the level switch varies widely based on the desired application, and the different factors aforementioned. As a result of those wide-ranging factors, level sensor designs can vary from the simple to the exceedingly complex. In addition, the level sensors can be triggered by many different conditions including pressure, temperature or buoyancy. Some additional features that more complex level sensors may include are thermal sensors, ultrasonic waves, vibrating sensors and optical sensors. All of these sensors can be modified to recognize specific substances or to reveal when a certain viscosity, density, opacity or thermal conductivity condition is reached. For construction, level sensor manufacturers typically utilize stainless steel, brass and a couple different types of plastics. Stainless steel is an excellent material choice due to its hygienic properties and high corrosion-resistance, whereas brass works exceptionally well for petroleum-based liquids. The two most common plastics that are used to fabricate level sensors are polypropylene and polysulfone. These two plastics offer advantages such as availability in different colors, good choices for acidic conditions such as in electroplating and metal cleaning as well as lower-temperature food processing applications.
