Abstract

The invention discloses a diaphragm-type digital pressure gauge, which comprises a pressure measuring module and a display module, wherein the pressure measuring module and the display module are electrically connected; the pressure measuring module comprises a pressure sensing sub module and a strain gauge, the pressure sensing sub module and the strain gauge are connected; the pressure sensing sub module is used for sensing the mechanical pressure of a measured medium; the strain gauge is used for generating electric signals characterizing the mechanical pressure according to the mechanical pressure; and the display module is used for receiving the electric signals and displaying a pressure value. Digital display is realized for the mechanical pressure, and the mechanical pressure measurement accuracy and the mechanical pressure measurement effectiveness can be improved.

Description

technical field [0001] The invention relates to the field of pressure measuring instruments, in particular to a diaphragm type digital pressure gauge. Background technique [0002] At present, there are many kinds of traditional pointer pressure gauges on the market, but the traditional pointer pressure gauges must be kept vertical during installation, and it is necessary to consider ensuring the center reference of the pointer of the pointer pressure gauge, and it can only be viewed horizontally, with parallax, The reading can only be estimated, and the error is large, especially in various environments including petroleum, chemical fiber equipment, textile machinery, wire drawing machine equipment, rubber equipment, etc., including high-temperature fluids, the reliability of traditional pointer pressure gauges is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects in the prior art that the traditi...
