Capacitive sensors reliably detect the minimum or maximum level of granulates in a container.
Ultrasonic sensors check the fill height of tanks.
Detect levels of liquids and solids using sensors
Do you need to reliably detect levels in containers? To find the right solution for your needs, please answer the following questions: What distance to the object do I need? Is the sensor allowed to contact the medium? How much space do I have available for installation? What ambient conditions do I need to account for (elevated temperatures, moisture, oil, dirt, etc.)? This is how you select the right technology.
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:
