Miniature Position Transducers (String Potentiometers (String Pots)) |
 |
These all-environment miniature displacement transducers are also referred to as draw wire transducers, string pots, string encoders, cable extension transducers, and yo yo pots. Complementary to LVDTs, encoders, linear potentiometers, and related displacement sensors, Firstmark Controls position transducers are noted for their small size, rugged performance, accuracy, flexible mounting, and easy installation. |
