Silica Techno is based in India and lists load cells, strain gauges, RTDs and CCTV cameras on Global Trade Plaza. The load cell is described as a transducer that converts force into a measurable electrical output, with strain gauge based types noted. The strain gauge is presented as an electrical sensor whose resistance changes with applied force to measure pressure, force, weight and tension. The RTD is listed as a temperature sensor that operates on the principle that a metal's resistance changes with temperature. The CCTV camera is described as sending a feed to a central control center for selection and display on monitors. Buyers can send an enquiry through Global Trade Plaza.
