Capacitive sensor for detecting levels – with or without medium contact – at close range
Detecting – Levels
Capacitive sensors reliably detect the level of granulate in a container. To accomplish this two sensors are attached in the container offset from each other. A signal is generated when the minimum or maximum level is exceeded. This prevents over-filling or falling of the level below a prescribed value, and reduces equipment downtime. Capacitive sensors are flexibly designed and simple to install.
Ultrasonic sensors detect the precise fill height of a tank without contact. They ensure that the filling process can run continuously. Ultrasonic sensors are also reliable over greater distances and require no additional component such as reflectors.
Various technologies can be used for detecting level depending on the application area:
- Capacitive sensors for detecting the presence or level of almost any material and liquid at close range (< 50 mm)
- Ultrasonic sensors for detecting virtually any object over greater distances (> 50 mm) using sound
