LMO Contactless Load Measurement System

India’s Technology Development Board (TDB), under the Department of Science and Technology (DST), provided financial assistance to Puretronics India Private Limited on 30 June 2026 for the commercialisation of its Load Magnetic Overload (LMO) Sensor. The company describes the LMO Sensor as India’s first fully contactless programmable load measurement system.

Contactless Load Measurement

The LMO system measures load through a non-contact magnetic sensing principle. Conventional load cells use mechanical strain gauges, while the LMO system uses magnetic sensors, digital signal processing, and programmable embedded electronics. The system is designed to measure load without direct mechanical contact with the sensing element.

Industrial Automation Applications

The LMO Contactless Load Measurement System is designed for integration with PLC, SCADA, and IoT-based industrial systems. PLC stands for Programmable Logic Controller, and SCADA stands for Supervisory Control and Data Acquisition. Such systems are used in industrial monitoring, control, and data collection.

Use Cases in Equipment Safety

The technology is intended for elevators, cranes, hoists, material handling equipment, and cable machinery. These machines require load monitoring for operational control, weight measurement, and equipment management. The system also aims to reduce maintenance and calibration needs in industrial use.

Important Facts for Exams

• The Technology Development Board functions under the Department of Science and Technology.
• Load cells commonly use strain gauges for load measurement.
• SCADA systems are used for supervisory control in industrial processes.
• IoT stands for Internet of Things and refers to connected devices and sensors.

Institutional Context

Puretronics India Private Limited developed the LMO Sensor as a commercial industrial technology. TDB Secretary Rajesh Kumar Pathak stated on 30 June 2026 that such innovations support the development of globally competitive industrial technologies in India.
