    Position sensorsHydraulics & Mining Technology

    The robust, intrinsically-safe position measuring (reed) rod for mining (type PR 116-020) is fitted into a hydraulic cylinder and determines the current travel of the cylinder. The PR116-020 consists of a sealed stainless steel rod with electronics concealed within. A ring magnet around its exterior ensures that a linear measuring voltage is contactlessly tapped, proportionate to the travel of the cylinder.
    The measurement signal is generated inside the sensor, thus ensuring that the required output voltage is available with correct polarity assured and short-circuit proof. The measurement is accurate to < 3 mm. The position sensor is available in various lengths.
