The invention provides a dial plate device for converting a digital remote transmission signal by a pointer, which is mainly applied to a pressure gauge and comprises a grating angular displacement sensor, a signal amplifier, a digital display, a communication circuit and a remote receiving unit. According to the device, the grating angular displacement sensor is arranged in the dial plate, the structure of the dial plate is not changed, the rotation angle of the pointer is measured by the grating angular displacement sensor, and then angle information of the pointer is converted into reading information through the signal amplifier and the digital display and is displayed. And reading information is sent to a remote operation terminal through a communication circuit and a remote receiving unit, so that operation and maintenance personnel can remotely master the state of the pressure gauge. Due to the fact that the grating angular displacement sensor is used for measuring readings, the measuring precision is
