Detailed description of the invention
In order to be better understood from the present invention, below in conjunction with specific embodiments and the drawings, the present invention is further retouched
State.
As Figure 1-3, a kind of anticorrosion digital pressure measures table, including pressure transmitter 7, described pressure transmitter 7
Outside is provided with a shell 2 with protective effect, and the material of described shell 2 is politef.The side of described shell 2 sets
There is lid 1, described lid 1 is offered porose, pressure conduction film 6, described pressure conduction film 6 and described pressure are installed in described hole
Power transmitter 7 is in close contact.It is provided with installation on lid 1 described in described housing 2 away from described pressure conduction film 6 one end
Hole, is provided with wiring 3 in described installing hole.One end of described wiring 3 is fixing with described pressure transmitter 7 to be connected, and the other end is fixed
Connect and have the display screen 4 for showing measurement result.
In the present invention, make to be positioned at the described pressure inverting of described shell 2 by arranging the shell 2 of politef material
