Description

technical field [0001] The invention relates to the technical field of pressure gauges, in particular to a remote pressure gauge equipped with a magnetic sensor. Background technique [0002] The remote pressure gauge is suitable for measuring the pressure of liquids and gases that do not corrode steel and copper alloys. A slide wire resistive transmitter is installed inside the resistance remote pressure gauge, so the measured value can be transmitted by electricity. To the relevant display instrument or computer far away from the measurement, so as to realize centralized detection and remote control. However, the existing remote pressure gauge is just a simple mechanical pointer pressure gauge. In the environment with large amplitude, the measured data is not accurate enough. The resistive transmitter has a certain remote transmission function, but it is within a certain range. It is more practical inside. When the relevant display instrument or computer and the remote pr...

[0003] The purpose of the present invention is to provide a remote pressure gauge equipped with a magnetic sensitive sensor, to solve the problem that the existing remote pressure gauge proposed in the background technology is a simple mechanical pointer pressure gauge, and it can , the measured data is not accurate enough. The resistive transmitter has a certain remote transmission function, but it is more practical within a certain range. When the relevant display instrument or computer and the remote pressure gauge are not in the same area, they cannot be connected by wires. At this time, the ordinary remote pressure gauge loses the function of remote transmission and cannot carry out effective remote monitoring
