Abstract
The utility model discloses a non-contact type standard current output angular displacement sensor, which comprises a casing (1), a spindle (2), a bearing (3) and a steel magnet (4). The spindle (2), the bearing (3) and the steel magnet (4) are arranged on one side inside the casing (1). One end of the spindle (2) is arranged in the bearing (3). The steel magnet (4) is arranged in the inner socket of the spindle (2). The non-contact type standard current output angular displacement sensor is characterized by also comprising a Hall integrated chip (5), a PCB circuit board (6), a voltage-current conversion chip (7) and a signal lead-out line (8). The Hall integrated chip (5), the PCB circuit board (6), the voltage-current conversion chip (7) and the signal lead-out line (8) are arranged on the other side inside the casing (1). A space is reserved between the Hall integrated chip and the steel magnet (4). The signal lead-out line (8) extends out of one end of the casing (1). Due to the adoption of the non-contact type standard current output angular displacement sensor, the value of the output standard current can be 0 to 20 mA or 4 to 20 mA. Thus, the non-contact type standard current output angular displacement sensor can be adapted to long-distance transmission, voltage-instable, current-instable and other occasions. The application range of the sensor is therefore enlarged.
