More Information
Summary:The invention discloses a position control device. The position control device comprises an induction wheel; a contact tongue is arranged on the induction wheel and can rotate along with the inductionwheel; and an over-travel limiting part is arranged outside the contact tongue and is used for limiting the contact tongue so as to prevent the motor output shaft synchronously rotating with the induction wheel from over-travel rotation. The invention further discloses a volume probe comprising the position control device. According to the position control device, the transmission overtravel riskcan be stopped from the source; the rotation of the output shaft of the motor is controlled through the limiting matching effect of the contact tongue on the induction wheel and the overtravel limiting part; compared with a traditional protection mechanism, the intermediate transmission mechanism does not bear internal stress any more, and the core part does not collide with any rigid part, so that the safety of the core
