Main advantages of E + H pressure transmitter:
1. The pressure transmitter has reliable operation and stable performance.
2. Special V / I integrated circuit, less peripheral devices, high reliability, simple and easy maintenance, small volume, light weight, extremely convenient installation and debugging.
3. Aluminum alloy die-casting shell, three end isolation, electrostatic spray protection layer, strong and durable.
4. 4-20mA DC two-wire signal transmission, strong anti-interference ability and long transmission distance.
5. LED, LCD, pointer three kinds of indicator, the field reading is very convenient. It can be used to measure viscous, crystalline and corrosive media.
6. High accuracy and stability. In addition to the imported original sensors that have been corrected by laser, the comprehensive temperature drift and nonlinearity of the whole machine within the operating temperature range are fine compensated.
Function: the E + H pressure transmitter transmits the pressure signal to the electronic equipment, and then displays the pressure on the computer. The principle is roughly as follows: the mechanical signal of water pressure is converted into current (4-20mA). The pressure of such electronic signal is in linear relationship with the voltage or current, which is generally proportional. Therefore, the voltage or current output by the transmitter increases with the increase of pressure, and a relationship between pressure and voltage or current is obtained.
The two pressures of the measured medium of the E + H pressure transmitter are introduced into the high and low pressure chambers. The pressure of the low pressure chamber is atmospheric pressure or vacuum, which acts on the isolation diaphragms on both sides of the sensitive element and is transmitted to both sides of the measuring diaphragm through the figueris isolation diaphragm and the filling liquid in the element. The pressure transmitter is a capacitor composed of the measuring diaphragm and the electrodes on the insulating sheets on both sides. When the pressures on both sides are inconsistent, the displacement of the measuring diaphragm is proportional to the pressure difference, so the capacitances on both sides are unequal, and are converted into signals proportional to the pressure through oscillation and demodulation. E + H pressure transmitter can sense the pressure of various objects, whether it is solid, liquid or even gas, so it is applied in many fields.
