ZCF series DC tachometer generatorDetailed product description：

Overview
The ZCF series DC tachometer generator is a closed self cooled separately excited DC generator with a steering gear. Under a constant excitation current, the armature voltage is proportional to the armature speed. This series of generators operates continuously. It has the characteristics of small linear error, reliable operation, small size, and light weight, and is used in automatic control systems and calculation and solution devices as components for speed measurement and feedback.
