Abstract
The utility model discloses an external zero setting digital pressure transmitter, which relates to the technical field of pressure transmitters and comprises a shell, a pressure sensor and a circuit board are arranged in the shell, a potentiometer is connected onto the circuit board, the pressure sensor and the potentiometer are both electrically connected with the circuit board, and the circuit board is electrically connected with the shell. One end of the shell is provided with a pressure connector, the other end of the shell is provided with a plug, the plug is electrically connected with the circuit board through a wire, the plug is locked on the shell through a locking ring, the locking ring is detachably connected with the shell, and after the locking ring and the plug are detached, the potentiometer is exposed out of a port of the shell. And the potentiometer can be adjusted through the port of the shell, so that the calibration of the pressure transmitter is realized. According to the digital pressure transmitter with the external zero setting function, calibration of the pressure transmitter can be achieved through the potentiometer of the digital pressure transmitter, calibration is convenient, and calibration cost is low.
