    (±60°). The transducers PR 9268/30x−x00 and PR 9268/70x−000 are specified for horizontal measurement (±30°). If the transducer is to be mounted in a direction different to the nominal measuring direction, Emerson recommends using a lifting or sinking current according to the angle deviation. The supplied current raises or drops the seismic mass of the sensor to keep it in the center of the movement range.
