Linear displacement sensor (LVDT sensor)

Linear differential transformer with variable gain. LVDT sensors are electromechanical transducers that convert the linear motion of an object to which they are mechanically connected into an electrical signal. HPHT sensors are designed to operate under overpressure and elevated temperatures. The sensors are fully compatible with rock mechanical properties testing equipment. The product complies with technical specifications: GEOL.410670.001TU. They can be used in various analytical equipment.
