Capacitive level sensor

Video describing how capacitive liquid level sensors work. This video illustrates the principles of Gill capac. The space between the tubes is the dielectric.

When the tube is empty, the space is occupied by air. The technique is frequently referred as RF as radio frequency signals applied to .

Liquid level sensing using capacitive sensing technology.

Rigid-flex circuit allows the sensors to be placed on various shaped surfaces.

CONTACT MOLEX ABOUT THIS PRODUCT . Solid-state capacitive liquid level sensors for fuel, oil, water and other liquids. Standard and custom level sensor configurations offering high accuracy and long -term reliability in harsh environments. Capacitive Fluid Level Sensors. Our capacitive level technology accurately measures the change in fluid level within standard and irregular tanks. As the liquid level changes, the amount of dielectric material between the plates changes, which causes the capacitance to change as well.

The sensors can be designed to sense material with . Continuous capacitance level measurement and point level detection works in liquids and solids with Liquicap, Liquipoint, Solicap and Minicap sensors. Figure 2: Ultrasonic liquid level sensor. Conductivity measurement: Two conductive electrodes are used to measure conductivity.

This method is reliable, compared to mechanical and ultrasonic measurements, but it cannot be used for beverages or flammable liquids. In this research, water level sensor . Liquid- level sensing based on capacitive . Maximum measurement resolution is achieved with this level sensor. Thanks to having no moving parts the level sensor is wear free and therefore maintenance free. The CAP-3capacitive level sensor is one of our most durable and reliable point level sensors.
