Smart Pressure Transmitter, 4-20mA, Hart, Modbus Output
1. Working Principle
The pressure transmitter is a commonly used sensor in industrial applications.
It is widely used in various industrial self-control environments, involving water conservancy and hydropower, railway transportation, intelligent building, production automation, aerospace, military, petrochemical, oil well, electric power, ship.
In many industries, such as machine tools and pipelines, the main role of pressure transmitters is to transmit pressure signals to display pressure on the computer.
The principle is rough as follows: the mechanical signal of the pressure of water pressure is converted into a current (4-20 mA), and the electronic signal pressure has a linear relationship, with the magnitude of the voltage or current, which is generally proportional.
Therefore, the voltage or current outputted by the transmitter increases with the increase of the pressure, thereby obtaining a relationship between pressure and voltage or current.
