ABB Level Switches
ABB level switches are a robust solution for high-integrity, reliable point level detection of liquids and bulk solids in industrial process applications. Known for their reliability and simplicity, ABB level switches provide a clear on/off signal to signify when a vessel has reached a specific fill or empty state. Applications include overfill protection, dry run detection, high level or low-level alarms, and equipment protection.
ABB's product portfolio is widely used for continuous level measurement in process automation. But these little-noticed, yet critical, products play an equally vital role in protecting pumps and other equipment, preventing overfill, and assuring process integrity. ABB brings industrial-grade quality and longevity to point level switch applications with its diverse offerings.
ABB level switches are available with conventional industrial outputs for use with PLCs, relays, alarms, motor controls, and safety shutdown. They are simple to commission and easy to operate in continuous use. Purpose-designed for arduous, industrial conditions, ABB level switches offer a choice of rugged housings, weather protection, wide temperature ranges, repeatability under vibration, cleaning, coating, and fouling resistance.
FAQs
What is an ABB level switch used for?
ABB level switches are used for point level detection to indicate high, low, or intermediate levels in tanks, vessels, silos, and pipelines, helping prevent overflow, dry-running, or equipment damage.
What types of level switches does ABB offer?
ABB offers vibrating fork level switches, capacitive level switches, and conductivity-based level switches designed for liquids, powders, and granular bulk solids in industrial processes.
Are ABB level switches suitable for harsh environments?
Yes, ABB level switches are designed to operate reliably in harsh conditions, including high temperatures, corrosive media, high vibration, and hazardous locations with appropriate approvals.
Can ABB level switches be used for both liquids and solids?
Yes, depending on the sensing technology, ABB level switches can be used for liquids, slurries, powders, and bulk solids such as grain, cement, plastics, and minerals.
How do ABB level switches connect to control systems?
ABB level switches provide discrete on/off outputs and support standard industrial wiring and communication, allowing easy integration with PLCs, relays, alarms, and control systems.
