In the wire sensor series S501P the mechanical detection of linear movement is done by the pretensioned cable wire. Inside the sensor the wire is wrapped on a drum which is tensioned by a helical spring. Pulling the cable wire the linear movement is transformed into a rotated movement. A multiturn potentiometer flanged on the drum converts the movement into an analog signal. For the S501P wire sensor only high quality multiturn potentiometer with hybrid technology are used. Due to the hybrid technology, in which the resistive wire of the potentiometer is covered with conductive plastic, a high performance in accuracy and long lifetime is reached. The flexible mechanical coupling of the wire construction makes the S501 suitable for application in which conventional linear transducers cannot be mounted to the measurement object. With an extended wire the S501P sensor can be installed in appropriate distance in case of very rough environmental conditions. The robust construction in IP65 protection compliments the high price performance ratio of the S501P wire sensor.
