ELB 10x Side-Mounted Level Switch: Stainless Steel Level Control for Industrial Tanks

Reliable level control is essential in industrial tanks, storage vessels, boilers, machinery systems and marine applications. In many processes, the level switch must operate safely under pressure, temperature and demanding liquid conditions while providing a clear electrical contact signal for pumps, solenoid valves or alarm systems.

The ELB 10x Side-Mounted Level Switch is designed for these requirements. With its stainless steel construction, horizontal mounting design, magnetic operating principle and durable contact structure, ELB 10x provides a robust and practical solution for point level detection in industrial liquid tanks.

What Is ELB 10x?

ELB 10x is a side-mounted mechanical level switch used for tank level measurement and control. It belongs to the ELB level switch family, which includes models such as ELB 10, ELB 10a, ELB 10e, ELB 10x, ELB 10h, ELB 11, ELB 12, ELB 21, ELB 22, ELB 31, ELB 41, ELB 51, ELB 61 and ELB 71.

The ELB 10x model is defined in the catalog as a complete stainless steel model. This makes it especially suitable for applications where stronger mechanical durability and corrosion resistance are required compared with standard aluminum-housing models.

Operating Principle

ELB level switches operate with a magnetic float mechanism. When the liquid level changes, the float arm moves according to the level position inside the tank.

A magnet located inside the float arm magnetically affects another magnet inside the body. This movement changes the position of the microswitch inside the housing.

The obtained contact signal can then be used in applications such as pump control, solenoid valve control, alarm systems or automation circuits.

This working principle keeps the electrical switching mechanism isolated from direct liquid contact while still providing reliable level indication.

Side-Mounted Installation

ELB 10x is designed for horizontal side mounting. This installation type is practical for tanks where level detection is required at a fixed point on the side wall.

Side-mounted level switches are commonly used for minimum level alarm, maximum level alarm, pump protection, overflow prevention or filling and emptying control.

The horizontal mounting structure also makes maintenance and installation easier in many tank designs.

Stainless Steel Construction

One of the most important advantages of ELB 10x is its stainless steel structure.

According to the catalog, the flange material is 316 stainless steel, the float material is 316 stainless steel, and the housing material is 304 stainless steel.

This material configuration provides durability for demanding industrial environments. Stainless steel construction is especially important in applications where corrosion resistance, process compatibility and long service life are required.

Technical Specifications

ELB 10x has a horizontal mounting structure. The minimum liquid density is 0.7 g/cm³ standard.

The flange dimensions are 92 mm x 92 mm. The maximum operating pressure and temperature are 25 bar / 250 °C.

The ambient temperature range is -20 °C to +80 °C. The protection class is IP65.

The product weight is approximately 3.5 kg, and the float test pressure is 40 bar.

These values make ELB 10x suitable for industrial level control applications where elevated process temperature and pressure resistance are required.

Electrical Output

For ELB 10e, ELB 10, ELB 10a, ELB 10h, ELB 10x and ELB 61 models, the catalog shows a terminal structure with COM, NO and NC contacts.

The contact rating is 125 / 250 VAC 15 A and 110 VAC 15 A.

This output allows ELB 10x to be connected to control panels, alarm circuits, pump control systems or solenoid valve control systems.

Application Areas

ELB level switches are suitable for food, marine, machinery, boiler and storage tank applications.

In these sectors, ELB 10x can be used for point level detection in liquid tanks where stainless steel construction and reliable switching are required.

Typical uses include high-level alarm, low-level alarm, pump start-stop control, overflow prevention and dry-running protection.

Advantages of ELB Series

The ELB series offers several important advantages. The catalog highlights maximum operating pressure up to 400 bar, maximum operating temperature up to 400 °C and a wide variety of accessories across the product family.

ELB models are preferred because of their high temperature resistance, long-life contact structure, stainless steel wetted parts and vertical or horizontal mounting options.

For ELB 10x specifically, the stainless steel housing and 316 stainless steel wetted parts provide an additional advantage in demanding environments.

Accessories and System Flexibility

The ELB catalog includes several accessories that can improve installation, testing and operation.

The test apparatus allows users to check whether the level switch operates correctly without emptying the tank. The counter flange and flange accessories support mechanical installation. The external tank can be used as a feed device.

The catalog also includes a contact apparatus, which can provide four independent contacts using an electronic card inside the ELB level switch housing. Contacts can be manufactured as NO or NC according to the order.

A bellows apparatus is available for liquids containing particles. It is designed to help the level switch perform its function in particulate liquid applications.

Installation and Maintenance Considerations

For reliable operation, ELB 10x should be installed at the required switching level on the tank wall. The float must have enough free movement inside the tank.

The liquid density should be suitable for the float. For ELB 10x, the standard minimum density is 0.7 g/cm³.

In applications with particles, turbulence or difficult process conditions, accessory selection should be evaluated carefully. The bellows apparatus or external tank option may help improve operation in specific conditions.

Why Choose ELB 10x?

ELB 10x is a strong choice when the application requires a robust, stainless steel side-mounted level switch for industrial tanks.

Its magnetic switching principle, stainless steel housing, 316 stainless steel wetted parts, IP65 protection, 25 bar pressure rating and 250 °C temperature capability make it suitable for demanding level control applications.

For users who need a reliable contact output for pump, valve or alarm control, ELB 10x provides a simple and durable solution.

Conclusion

The ELB 10x Side-Mounted Level Switch is a stainless steel mechanical level switch designed for reliable point level control in industrial tanks. With horizontal installation, magnetic float operation, 316 stainless steel flange and float, 304 stainless steel housing, 25 bar / 250 °C maximum process conditions and 15 A contact output, it provides a dependable solution for liquid level monitoring.
