About Contisys Technologies
A subsidiary of Continental Engineering Works, Contisys Technologies Private Limited manufactures precision Hall Effect current and voltage sensors for railway, EV, renewable energy, and industrial applications.
Precision in Power, Excellence in Measurement
Contisys Technologies was established to serve the growing demand for high-reliability current and voltage sensing in safety-critical industrial applications. Building on decades of engineering expertise within the Continental Engineering Works group, we bring railway-grade quality standards to every product we manufacture.
Our sensors are designed for the most demanding environments — railway traction systems, EV charging infrastructure, solar inverters, and industrial motor drives — where measurement accuracy directly impacts system safety and efficiency.
With manufacturing and R&D facilities in Kolkata and Pune, we provide complete in-house capability from sensor design to final test and calibration.
