5. Detailed Product Description

Working Principle

The UQK-T float level switch is a liquid level instrument designed and manufactured on the magnetic coupling principle. When the liquid level in the container fluctuates, the magnetic force mechanism drives the magnetic control switch or bias magnetic steel, causing the switch contacts to open or close. When the liquid level falls, the magnetic body moves down and the magnetic control switch returns to its original state or reaches a new balanced position under gravity, again switching the contacts on or off. In this way, the UQK-T realizes reliable liquid level control and alarm.

Design & Construction

Built with a sealed magnetic coupling mechanism, the UQK-T keeps all switching elements isolated from the process medium, which effectively eliminates leakage risk and minimizes wear. The flameproof enclosure (Exd CT4 ~ T6) and IP65 protection rating allow safe and stable operation in hazardous and demanding industrial environments, while the all-stainless-steel wetted construction ensures excellent corrosion resistance.

Reliability in Harsh Conditions

The UQK-T operates stably and reliably at working pressures up to 25 MPa (1500 LB) and temperatures from -40°C to +300°C. With 1-4 optional control points and 2-4 simultaneous switching outputs, it delivers accurate and repeatable level control, making it an ideal replacement and upgrade for traditional mechanical level switches.
