Pressure meter with pointer with light pillar display function

Abstract

The invention discloses a pressure meter with a pointer with the light pillar display function. A traditional pressure meter is replaced. The measuring modes including resistance teletransmission, Hall teletransmission, differential teletransmission and the like are changed. The problems that the traditional teletransmission pressure meter is only provided with an indirect sampling sensor, output values are instable, signals are asynchronous, and the structure is complex are solved. A strain sensor of the pressure meter can achieve full sealing, and the pressure meter has the stability, the anti-vibration performance and the synchronism; meanwhile, the structure is simple, and installation and debugging are convenient. In addition, a strain gage is pasted to the metal surface and changes along with metal deformation, and a voltage is output under the effect of the bridge voltage. When pressure is measured through the pressure meter, a spring pipe will change, the strain gage also changes, and a light pillar display screen detects change voltage signals and directly displays change pressure values. The shape of the pressure meter is not changed. By means of the pressure meter with the light pillar display function, the pressure values can be easily read and observed under the poor light condition, and observing dead zones can not be formed.

Description

technical field

[0001] The invention relates to a pressure measuring gauge, in particular to a pressure gauge with a pointer and a light column display. Background technique

[0002] A pressure gauge is an instrument that uses elastic elements as sensitive elements to measure and indicate pressure higher than the environment. It is widely used, and it pervades almost all industrial processes and scientific research fields. It can be seen everywhere in heat pipe network, oil and gas transmission, water supply and gas supply system, vehicle repair and maintenance factory and shop. Especially in the process of industrial process control and technical measurement, due to the high mechanical strength and convenient production of the elastic sensitive components of mechanical pressure gauges, mechanical pressure gauges are more and more widely used. Strain pressure gauges collect signals directly on the surface of the spring tube of the pressure gauge, which overcomes the traditi...
