BEL, Aug 13

The Hon’ble Raksha Mantri, Shri Rajnath Singhji, on Thursday, August 13, 2020, launched through Video Conference two products — Linear Variable Differential Transducer (LVDT) and 1kW Transmitter Aerial Switching Rack, indigenously developed for use in various strategic applications, as part of the Government of India’s Atmanirbhar Bharat initiative.

Mr Gowtama M V, Chairman & Managing Director, Bharat Electronics Limited (BEL), on the occasion gave a presentation to the Hon’ble Raksha Mantri on these products, which have been indigenously developed by BEL.

Linear Variable Differential Transducer (LVDT) is a Motion Sensing and Feedback Control device, which has been developed primarily for supply to DRDO labs Gas Turbine Research Establishment (GTRE) and Research Centre Imarat (RCI). Due to its high accuracy of functional parameters, LVDT finds applications in Aerospace, Missiles, Solar, Aircraft Engines, Wind energy and Naval systems, and works in adverse climatic conditions. LVDT has been designed and developed for customised retrofit requirement. The development of this product is a huge step for India towards self-reliance and is an import substitute saving the Country Foreign Exchange (FE) to the tune of Rs. 100 Crores over the next two to three years’ time.  

The 1kW Transmitter Aerial Switching Rack (ASR) has been designed completely in-house by BEL, to be supplied as part of the Advanced Composite Communication System (ACCS) onboard Indian Naval ships. The configuration caters for switching four numbers of High Frequency (HF) Transmitters to four numbers of HF Antenna with Antenna Tuning Unit (ATU) in any combination. This enables users to switch any radio to any of the Antenna for redundancy. The system can be remotely controlled in the IP based Network.

The ASR is an import substitution for the HF Aerial switching Unit from USA and is likely to bring in FE savings of about Rs. 30 lakhs per unit.
