MBKSSOAA1A0150DAA
The MBKS Top Mounted Magnetic Float Level Switch is a highly reliable, passive magnetic liquid level controller engineered for precise multi-point detection in industrial storage tanks, vessels, and sump pits. Operating on basic buoyancy and magnetic induction principles without requiring external power, the MBKS series features customizable insertion lengths up to 6000mm, up to 8 configurable switching points, and robust explosion-proof certifications (Ex db IIC T6 Gb / Ex db IIC T6...T3 Gb X), making it an ideal choice for challenging chemical, water treatment, and oil & gas process automation environments.
The MBKS Series Top Mounted Magnetic Float Level Switch engineered by leading automation instrumentation standards offers an exceptional passive control solution for high and low liquid level alarms, pump control, and automated process management. Utilizing a heavy-duty float embedded with a permanent magnet assembly, the switch effortlessly glides along a vertical guide tube driven by medium buoyancy. As the float passes designated measurement positions, internal dry reed switches open or close instantly without physical contact or mechanical wear, ensuring an extraordinary operational lifespan of up to one million cycles.
Designed for versatile vertical top-mounting with flange or threaded process connections, the MBKS controller can be tailored with up to 8 independent actuation points and supports a broad range of corrosive, viscous, or explosive media thanks to its optional 304, 316L, Titanium, PP, and PTFE dynamic construction choices. With zero standby power consumption and full immunity to dielectric constants, foam, pressure fluctuations, or vapor turbulence, the MBKS series provides ultimate long-term measurement stability for industrial automation systems worldwide.
FAQ
Q1: What is the operating principle of the MBKS float level switch?
A1: The MBKS switch operates based on the principle of buoyancy and magnetic field induction. As the liquid level rises or falls, a magnetic float moves along the dynamic guide tube to trigger dry reed switch contacts inside, achieving non-contact level switching without requiring external operating power.
Q2: How many switching points can be configured on a single MBKS unit?
A2: A single MBKS top-mounted controller can be customized with up to 8 individual switching points for NO (Normally Open) or NC (Normally Closed) logic, and up to 6 switching points for SPDT (Changeover) contacts.
Q3: Can the MBKS level switch be used in hazardous or explosive areas?
A3: Yes, the MBKS series offers robust explosion-proof explosion housing options certified to CNEX Ex db IIC T6 Gb and EAC 1Ex db IIC T6…T3 Gb X standards, making it safe for volatile industrial environments.
Q4: What media conditions are suitable for the MBKS level switch?
A4: It is suitable for liquids with a density of ≥0.5 g/cm³. With material options including 304, 316L, Titanium, PP, and PTFE, it reliably handles water, organic acids, light oils, alkaline solutions, and corrosive chemical liquids.
Q5: Is external power required for the MBKS series to function?
A5: No, the reed switch contact contacts are passive (dry contacts) and do not require external driving power, simplifying site wiring and enhancing long-term operational safety.
