What is India’s First Contactless Load Measurement System?

About: India’s first fully contactless programmable Load Measurement System, called the LMO (Load Magnetic Overload Sensor), is an indigenous next-generation load sensing technology.
- It accurately measures load without physical contact between the sensing element and the measured component.
Developed By: It is developed by Puretronics India Pvt. Ltd. with commercialization support from the Technology Development Board (TDB) under the Department of Science and Technology (DST).
- The Board has supported 444 agreements, committed over ₹3,261.60 crore, and facilitated creation of 70,000+ jobs across sectors.
Purpose: The system accurately measures load and overload conditions in safety-critical equipment without physical contact.
- It aims to improve industrial safety, operational reliability, and automation efficiency while reducing dependence on imported sensing technologies.
Technology: Unlike conventional strain-gauge load cells, the LMO uses a non-contact magnetic sensing principle.
- It detects load through changes in magnetic characteristics rather than mechanical deformation, eliminating direct physical contact.
Components: The platform integrates high-resolution magnetic sensors, advanced digital signal processing (DSP), and programmable embedded electronics.
- Together, these ensure highly accurate, configurable, and real-time load measurement.
Programmable Architecture: Its programmable design enables application-specific customization, configurable overload limits, and seamless adaptation across different industrial machines.
Industrial Integration: The system supports direct integration with PLC (Programmable Logic Controller), SCADA (Supervisory Control and Data Acquisition), and IoT-based industrial automation platforms.
- It enables continuous monitoring, predictive maintenance, and smart factory operations under Industry 4.0.
Applications: The LMO is designed for elevators, cranes, hoists, material-handling systems, cable machinery, and other safety-critical industrial equipment requiring precise load monitoring.
Advantages: The contactless design offers minimal calibration, low maintenance, high vibration resistance, simplified installation, and reliable operation even in harsh industrial environments.
- The technology strengthens India’s indigenous industrial electronics capability, promotes import substitution, and advances the national vision of Atmanirbhar Bharat in advanced sensor manufacturing.
- It represents a major advancement in India’s industrial automation, and advanced electronics ecosystem.
- Commercial production is expected to provide cost-effective, globally competitive sensing solutions, strengthening India’s industrial supply chain.
