High anti-vibration gas density monitor

A high anti-vibration gas density monitor, comprising:

• a monitor enclosure in which a sealed compartment filled with anti-vibration oil or hermetically filled with gas is provided;
• an indication value display mechanism in the sealed compartment, the indication value display mechanism comprising a Bourdon tube, a base, an end holder, a temperature compensation element, a movement, a pointer, and a dial;
• a signal control mechanism in the monitor enclosure and outside the sealed compartment, the signal control mechanism comprising a corrugated pipe, a first sealed cavity and a second sealed cavity, a signal generator, and a signal regulation mechanism, wherein the signal control mechanism and the indication value display mechanism are in gas communication with each other, and the corrugated pipe is provided in the second sealed cavity;
• one end and an other end of the corrugated pipe are sealed to form the first sealed cavity, compensation gas is provided in the first sealed cavity of the corrugated pipe, and the second sealed cavity is in communication with an electrical device;
• the signal control mechanism monitors a gas density by using the corrugated pipe, the first sealed cavity and second sealed cavity;
• and when the gas density in the electrical device changes, the corrugated pipe is compressed or expanded to produce an axial displacement so as to drive the signal regulation mechanism to trigger the signal generator to generate a signal;
• wherein one end of the Bourdon tube is fixed to the base, both an other end of the Bourdon tube and one end of the temperature compensation element are fixed to the end holder, an other end of the temperature compensation element is directly connected to the movement or connected to the movement via a connection arm and a connecting rod, the pointer is mounted on the movement, and the dial is mounted in the sealed compartment;
• and
• wherein the Bourdon tube is an elastic element that corrects a changing pressure and temperature by the temperature compensation element to reflect a change of the gas density, an end of the Bourdon tube is forced to elastically deform, displacement of the end of the Bourdon tube is transmitted to the movement, then to the pointer via the movement, and a density value is indicated on the dial.
