Pressure transmitter data acquisition device and method

Abstract

The invention discloses a pressure transmitter data acquisition device and method. According to the device, one end of a communication interface is connected with a communication module, and the other end is connected with a data acquisition module; an acquisition interface is connected with the data acquisition module; the data acquisition module comprises a data acquisition chip and a plurality of precision resistors, the data acquisition chip is fixedly connected with the shell, precision resistors are arranged between the data acquisition chip and the acquisition interface, and the data acquisition chip is used for acquiring data of a pressure transmitter through the acquisition interface; and the communication module is in communication connection with a control terminal and is used for receiving the data of the pressure transmitter acquired by the data acquisition module through the communication interface and sending the data of the pressure transmitter to the control terminal. According to the device, the data acquisition module, the communication module and other components are integrated, so on the premise of ensuring acquisition precision and speed, technicians can realize zero error without professional technical knowledge, meanwhile, the field wiring workload is also greatly reduced, connection and use can be realized, and complex debugging is not needed.
