TOREX® Bin Level Indicators ILT: Reliable Level Monitoring for Bulk Solids Storage

Accurate level monitoring is essential for efficient bulk solids handling.

Accurate level monitoring is essential for efficient bulk solids handling. Whether installed on silos, hoppers or bins, reliable level detection helps prevent overflow, avoid empty running conditions, minimise downtime and maintain uninterrupted material flow.
Across industries handling powders and granular materials, dependable level control plays a vital role in ensuring process efficiency and operational safety. An inaccurate or delayed level signal can result in material losses, unnecessary plant interruptions and reduced productivity.

To meet these challenges, WAMGROUP offers the TOREX® Bin Level Indicator ILT —a compact, robust and cost-effective solution designed to provide dependable level detection across a wide range of bulk solids applications.

Developed by TOREX®, the WAMGROUP brand specialising in components for bulk solids handling and discharging as well as equipment for pneumatic conveying, the ILT range combines a proven mechanical operating principle with versatile installation options, certified configurations and long-term reliability.

Tried and tested for reliable performance
The TOREX® ILT is designed to provide electrical signalling of minimum or maximum material levels inside silos, hoppers and bins through a simple yet highly reliable operating principle.

A rotating paddle is positioned at the required detection point and turns continuously under normal operating conditions. When the material reaches the paddle, its rotation is obstructed, generating a torque reaction that stops the motor and changes the status of the output relay. This signal immediately alerts the plant’s control system or the operator that the pre-set level has been reached.

As the material level falls below the paddle, the relay automatically returns to its original position and the motor resumes operation.

This straightforward mechanical concept ensures consistent performance while minimising complexity, making the ILT an ideal solution for continuous level monitoring in demanding industrial environments.

Engineered for Industrial Applications
Designed to withstand challenging operating conditions, the ILT range combines robust construction with straightforward installation and integration.

The indicators are suitable for internal silo pressures up to 0.8 bar, with operating temperatures ranging from -20 °C to +60 °C and process temperatures from -20 °C to +80 °C.

To accommodate different installation requirements, the range offers multiple process connections, including 1½" and 2½" ISO 228 as well as 1¼" NPT, with connection materials available in either plastic or aluminium.

Additional accessories—including threaded bushes, double paddles for low-density materials and shaft extensions—allow the device to be configured to suit different bulk materials and storage geometries.

This flexibility makes the TOREX® ILT equally suitable for new installations and retrofit projects.

Certified Solutions for Industry-Specific Requirements
Different applications require different levels of compliance.

For hazardous areas where combustible dusts may be present, an ATEX-certified version is available. WAMGROUP also offers the ILTROF food-grade version, specifically designed for applications where hygiene and material compatibility are key requirements.

These dedicated versions make the ILT suitable for a broad range of industries, including:
• Animal Feed
• Cement and Concrete
• Food Processing
• Plastics
• Quarrying and Mining
• Heavy Industry

In each of these sectors, reliable level monitoring helps improve storage management, enhance process control and reduce the risk of overflow or material shortages.

Designed to Simplify Plant Operation
Beyond its technical performance, the TOREX® ILT has been developed to integrate seamlessly into everyday plant operations.

Its rotating paddle technology provides direct mechanical detection of material presence, while the electrical output enables straightforward integration with plant automation and control systems.

For plant operators, this means greater control over filling and discharge operations, fewer production interruptions and improved coordination between storage, feeding and downstream process equipment.

Supported by the WAMGROUP Global Network
Selecting the TOREX® ILT also means benefiting from the experience and worldwide presence of WAMGROUP.

Through its global network of manufacturing facilities, subsidiaries and technical support teams, WAMGROUP ensures product availability, application expertise and reliable spare parts supply wherever customers operate.

This global support is particularly valuable for industries where equipment availability and operational continuity are critical.
