The utility model relates to the technical field of transmitter structures, in particular to a visual vacuum transmitter, which comprises a switch, a charging interface, a transmission interface, a base, a sensor, a display screen and a main control board, the main control board is connected with the display screen, the switch, the charging interface and the output interface through cables. Wherein the sensor is connected with the main control board through a cable, and a measuring structure of the sensor is a double-vacuum-gauge-tube bridge circuit structure; a heat conduction signal of the sensor is integrated and calculated to obtain a voltage signal, the voltage signal is acquired by the chip and is subjected to analog-to-digital conversion, a vacuum degree display program preset by the chip is used, and a vacuum degree numerical value is displayed on the display screen. The utility model solves the problem that the vacuum value of the system cannot be directly read in the maintenance process of the vacuu
