Abstract

The invention provides a novel piezoresistive pressure transmitter, which is characterized by comprising a shell, stop valves, a converter, a piezoresistive sensor, a pressure measurement element, a waterproof layer, a display screen, a cover plate, a moisture absorption layer, a detection pipeline, a flow dividing pipeline, a signal amplifier, a communication interface and a sealing ring, and is characterized in that one side of the shell is provided with the display screen, the upper side of the display screen is provided with the cover plate, the inner side of the display screen is provided with the moisture absorption layer, the lower side of the shell is provided with the detection pipeline, and the detection pipeline is provided with the stop valve. The novel piezoresistive pressure transmitter is provided with the flow dividing pipeline, thereby being capable carrying out flow division on a liquid or a gas flowing in the detection pipeline. When the novel piezoresistive pressure transmitter goes wrong, cannot carry out detection or transmission and needs to be maintained, the stop valve on the detection pipeline is opened, the stop valve on the flow dividing pipeline is closed, and the detected liquid or gas passes from the flow dividing pipeline, thereby ensuring smooth maintenance of the novel piezoresistive pressure transmitter.
