Track the position of hydraulic cylinders and other components that move in a straight line. Like a tape measure, these transmitters have a wire that extends to measure how far components have traveled from a set point. Because of the wire, they're also known as string pots—short for string potentiometers. They convert measurements to an electrical signal, which can then be used to trigger automated actions in your process.
All are IP rated for some protection from dust. Transmitters rated IP67 seal out water when briefly submersed.
Transmitters with a plug are quicker to connect and disconnect than those with wire leads. Plug them into a cable with a socket (sold separately).
