Hemomatik Hmfb-o Level Switch

What is the Hemomatik HMFB-O Level Switch?

The Hemomatik HMFB-O is a magnetic float-based level switch used to indicate and measure liquid levels in tanks, vessels, and pipes. It incorporates a magnetic float that moves up or down with the liquid level, which in turn activates an electrical contact to give level status information.

Its rugged but simple design makes it work well for a wide variety of fluids, such as water, oils, chemicals, and even some aggressive liquids when properly equipped with compatible materials.

Features of the Hemomatik HMFB-O Level Switch

The Hemomatik HMFB-O Level Switch is filled with functionality that makes it a first choice for demanding marine and industrial environments:

1. High Reliability and Accuracy
Due to its float-based construction, the HMFB-O provides extremely accurate and repeatable level sensing, unhampered by foam, vapor, or condensation.

2. Robust Construction
Made from high-grade stainless steel or engineered plastics, it is resistant to corrosion, guaranteeing long service life in even severe or corrosive environments.

3. Robust and Versatile Design
The level switch comes with a compact size that makes it simple to install in tight spaces or retrofit into current systems.

4. Simple Installation
It is easily adaptable to numerous mounting configurations—side mount, top mount, or bottom mount—giving you installation versatility with different tank configurations.

5. Configurable Configurations
The HMFB-O can be set up for single-point or multi-point level sensing, enabling you to measure multiple liquid levels using a single device.

6. Low Maintenance
Since there are no moving electrical components within the liquid, maintenance needs are kept to a minimum compared to other sensors.

7. Wide Electrical Compatibility
Compatible with conventional control systems (PLC, relay logic, alarm systems), the level switch is available in various voltage ranges, facilitating easy integration.

How Does It Work?

The Hemomatik HMFB-O works based on the magnetically actuated reed switch principle. The following is a simplified description:

• A float with a magnet travels up and down with the liquid level.
• A reed switch is encapsulated within a sealed stem outside the liquid path.
• When the float reaches predetermined points, the magnetic field switches on the reed switch, which changes its electrical state (open/closed).
• Your control system uses this change to activate alarms, pumps, or other automated functions.
• This unobtrusive switching scheme provides outstanding reliability and electrical isolation.
