Abstract

The invention discloses a pressure transmitter in the technical field of electronic components. The pressure transmitter includes a first entrance, a second entrance, a first pressure sensing unit, a second pressure sensing unit, a first signal processing conversion unit and a second signal processing conversion unit; the bottom end of the first entrance is in penetrating connection with the second entrance; the left and right sides of the connecting part of the first entrance and the second entrance are respectively connected to the first pressure sensing unit and the second pressure sensing unit; and the left side of the first pressure sensing unit and the right side of the second pressure sensing unit are respectively connected to the first signal processing conversion unit and the second signal processing conversion unit. Through the arrangement of one or more pressure sensing units and one or more signal processing conversion units on the device, the purpose of online pressure detection can be realized, the problem that pressure transmitters cannot be metered online can be solved, so that the pressure transmitter is strong in economic practicability.

Description

technical field [0001] The invention relates to the technical field of instruments and meters of the Department of Physics, in particular to a pressure transmitter. Background technique [0002] A pressure transmitter is a device that converts pressure into a pneumatic signal or an electric signal for control and remote transmission. It can convert the physical pressure parameters such as gas and liquid felt by the load cell sensor into a standard electrical signal (such as 4~20mADC, etc.), to supply secondary instruments such as indicating alarms, recorders, regulators, etc. for measurement and indication and process regulation. [0003] The existing pressure transmitter is mainly composed of a pressure sensing unit, a signal processing unit and a conversion unit, and a display unit is partially added, and there is a certain continuous function relationship between the output signal and the pressure variable. [0004] There is only one pressure inlet of the existing press...
