Pressure Transmitters high sensitivity, high accuracy, strong anti-overload. Imported sensor manufacturers, sensor and amplifier circuit highly integrated, die-cast aluminum alloy shell surface paint, circuit zero and gain adjustment need; anti-interference ability, acid, long-term stable and reliable.
Second, the principle
Selection of imported pressure transmitter pressure chip, sensitive components using diffusion or ion implantation process to form resistor and connected into a Wheatstone bridge, using micro-machining technology in the electric bridge a pressure-sensitive diaphragm. When the pressure on the diaphragm, the resistance value changes and generates a linear output signal proportional to the applied pressure. We add a DC power supply in a Wheatstone bridge, it will produce a DC output voltage signal. After two conversion lines, two-wire 4 ~ 20MA output.
Good stability, full-scale, long-term stability of zero up to 0.2% FS / Year. The compensated temperature range of 0 ~ 50 . the temperature drift is less than 0.2% FS, the entire operating temperature range of less than 0.5% FS.
Having reverse protection, current limiting protection circuit, when installing the positive and negative reversed not damage the transmitter, abnormal
Transmitter will automatically limit the flow in less than 35MA.
Solid-state structure, no moving parts, high reliability, long life
From pressure to water, oil can be highly accurate measurements, not influenced by the quality of the measured medium size.
Easy installation, simple structure, economic and durable.
