SP1 - String Pots & Draw-wire Sensors
The Celesco SP range of cable extension transducers (also known as string pots or draw-wire sensors) offer you a cost effective solution for measuring linear displacement in a very space efficient package. With measuring ranges from 4 inches (100mm) to 50 inches (1270mm) the SP units are very popular for external measurement of hydraulic and pneumatic cylinders. The SP1 variant has an exposed potentiometer at the back of the unit.
