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 dropping below a safe level.

Level Sensors: Innovations and Improvments

Manufacturers who utilize level sensors most often take extra measures to ensure there are no unwanted containments or particles introduced into their applications. One interesting innovation in the level sensor field 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 and is beneficial for applications where biohazardous materials may be present. These innovations can be pre-programmed with customer specified level ranges.

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.
