In industrial and commercial applications, especially in refrigeration technology, reliable monitoring of the liquid level is crucial for the safe and efficient operation of machines and systems. This includes refrigerant compressors, oil separators and receivers. KRIWAN, a leading manufacturer in this field, offers innovative solutions with its optical level sensors, which have been developed for precise and non-contact single-point measurement of liquid levels.
How the optical level sensors work
KRIWAN's optical level sensors work on the basis of an optical measuring principle that can be used universally in various media, such as refrigerants, oils and even liquids like fruit juices. The sensors consist of two main components: the screw-in part and the evaluation unit.
Advantages and areas of application
The optical level sensors from KRIWAN offer numerous advantages that make them an ideal choice for monitoring liquid levels in industrial applications:
Applications in refrigeration technology
The optical level sensors from KRIWAN protect refrigerant compressors in particular from critical operating conditions such as leaks, oil deposits in the refrigeration circuit or other faults. This contributes significantly to extending the service life of compressors and increases operational reliability. They are also suitable for use in oil and refrigerant receivers and oil separators.
The availability of different thread types for the screw-in part is particularly advantageous, allowing the sensors to be flexibly adapted to different systems and natural refrigerants such as ammonia (NH₃) and carbon dioxide (CO₂).
Technical innovation: level sensor with M12 plug connection
A particular highlight of the KRIWAN level sensors is the latest generation of level sensors, which are equipped with an M12 plug-in connection. This connection, which complies with the DIN43650 standard, enables quick and easy cabling, which considerably simplifies installation in production and connection to the plant control systems.
The level sensor also offers the following features:
With this combination of robust design, high temperature resistance, flexible power supply and simple installation, the new level sensor is ideal for industrial use.
