Baumer is a well-known company that manufactures a variety of sensors, including level sensors used for measuring the level of liquids or solids in industrial applications. The Baumer level sensors are widely recognized for their precision, reliability, and ease of integration into various systems.
Types of Baumer Level Sensors:
Capacitive Level Sensors:
Principle: These sensors measure the change in capacitance between two conductive plates, which varies with the level of material between them. The sensor detects this change and converts it into an output signal.
Applications: These are ideal for non-contact level measurements in bulk material or liquids, such as in tanks, silos, and pipelines.
Ultrasonic Level Sensors:
Principle: Ultrasonic level sensors use sound waves to measure the distance between the sensor and the surface of the material. The sensor emits ultrasonic waves and measures the time it takes for the waves to reflect back from the surface.
Applications: These sensors are used in environments where direct contact with the material is not possible or desired, like in dusty or corrosive environments.
Radar Level Sensors:
Principle: Radar level sensors operate similarly to ultrasonic sensors but use microwave radar instead of sound waves. These waves are emitted from the sensor and reflect off the surface of the material to calculate the level.
Applications: Ideal for high-precision and non-contact measurement in a wide range of industrial applications, especially in extreme conditions (e.g., high pressure, temperature, or vacuum).
Float-Based Level Sensors:
Principle: A float is used to physically float on the surface of the liquid. The movement of the float is translated into an electrical signal that represents the liquid level.
Applications: Typically used in applications where a simple and reliable solution is needed, such as in fuel tanks or water treatment plants.
Magnetic Inductive Level Sensors:
Principle: These sensors use a magnetic field generated by a magnet attached to the float to detect the liquid level. When the float moves with the liquid level, the sensor detects the magnetic field and outputs a corresponding signal.
Applications: These are often used in applications where the medium is corrosive or where other types of sensors may not be as effective.
Optical Level Sensors:
Principle: Optical level sensors use light to detect the presence or absence of a liquid at a specific point. The sensor uses a light beam that is reflected back when the liquid is present, enabling precise detection.
Applications: These sensors are typically used for point level detection in tanks or containers, particularly when there is a need to detect a specific fill level.
