Abstract

The invention relates to an electric signal pointer type rotating indicator, which comprises an original meter shell, wherein the original meter shell is provided with a dial and a pointer, the end, which is away from the dial, of the original meter shell is provided with a motor potentiometer and a circuit board, the motor potentiometer is electrically connected with the circuit board, and a rotating shaft of the motor potentiometer is coaxially connected with a rotating shaft of the pointer; the circuit board is provided with a motor driving circuit, a first input sampling circuit, a secondinput sampling circuit, a feedback circuit, a power supply circuit and an amplification comparator. According to the electric signal pointer type rotating indicator, an externally inputted electric signal can be processed through a circuit, and then the mechanical pointer is driven through the motor potentiometer to rotate by a specific angle, so that data indication can be realized in an occasionor environment without a pressure source.

Description

technical field [0001] The invention relates to a signal conversion indicating device, in particular to an electric signal pointer type rotary indicator. Background technique [0002] The traditional pointer pressure gauge uses elastic elements (generally dry reed switch, diaphragm, bellows) as the sensitive element. When the pressure is felt, the sensitive element will be displaced due to deformation, and the pointer will be driven to point to the rated scale through the transmission device. . [0003] Traditional pointer pressure gauges are generally widely used in factory production pressure measurement control, safety monitoring and other occasions. However, the traditional pointer pressure gauge can only be measured and displayed under the condition of a pressure source (gas, liquid, etc.), and it is powerless in some occasions or environments without a pressure source but where the scale needs to be indicated. . Contents of the invention [0004] The purpose of th...
