Description

Multifunctional detection pressure transmitter

Technical Field

The utility model relates to a pressure transmitter field specifically is a multi-functional detection pressure transmitter.

Background

A pressure transmitter is a device that converts pressure into a pneumatic signal or an electric signal for control and remote transmission. The pressure sensor can convert physical pressure parameters of gas, liquid and the like sensed by the pressure element sensor into standard electric signals (such as 4-20 mADC and the like) so as to supply secondary instruments such as an indication alarm instrument, a recorder, a regulator and the like for measurement, indication and process regulation. The pressure transmitter is the most common sensor in industrial practice, is widely applied to various industrial automatic control environments, and relates to various industries such as water conservancy and hydropower, railway traffic, intelligent buildings, production automatic control, aerospace, military industry, petrochemical industry, oil wells, electric power, ships, machine tools, pipelines and the like. Pressure transmitters are classified into two types, electric and pneumatic. The electrodynamic type unified output signal is a direct current signal of 0-10 mA, 4-20mA or 1-5V, etc. The pneumatic unified output signal is gas pressure of 20-100 Pa. The pressure transmitter can be divided into force (torque) balance type, capacitance type, inductance type, strain type, frequency type and the like according to different conversion principles, and the following briefly introduces the principles, structures, use, overhaul, check and other knowledge of several pressure (differential pressure) transmitters. The pressure transmitter is mainly used for transmitting a pressure signal to electronic equipment, and then the principle of displaying the pressure on a computer is that: the pressure of an electronic signal, which is an electronic signal for converting a mechanical signal of the pressure of water pressure into current (4-20mA), is in a linear relationship with the voltage or the current, and is generally in a direct ratio relationship. Therefore, the voltage or current output by the transmitter is increased along with the increase of the pressure, so that two pressures of a measured medium of the pressure transmitter with a relation of the pressure and the voltage or the current are obtained, the two pressures are introduced into a high pressure chamber and a low pressure chamber, the pressure of the low pressure chamber adopts the atmospheric pressure or vacuum, acts on the isolation diaphragms on the two sides of the delta element (namely a sensitive element), and is transmitted to the two sides of the measurement diaphragm through the isolation diaphragms and filling liquid in the element.

The display screen of the traditional pressure transmitter often encounters the problems of collision and the like, and the condition that the screen surface is damaged to influence the follow-up observation occurs for a long time.

Based on this, the utility model designs a multi-functional detection pressure transmitter to solve above-mentioned problem.
