Pulse g 130 pressure transmitter pressure sensor Differential Pressure Transmitter Differential Pressure Sensor High pressure two holes measuring an overview of pressure transmitter, high sensitivity, high accuracy, strong anti-overload. Imported sensor manufacturers, sensor and amplifier circuit highly integrated; die-cast aluminum alloy casing surface paint, no zero and gain adjustment circuit; interference ability, acid, long-term stable and reliable. Second, the principle of imported pressure pressure transmitter 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 to form a pressure sensitive diaphragm. When the pressure on the diaphragm, the resistance value changes and is proportional to the applied pressure produces a linear output signal. We Wheatstone bridge together with the DC power supply, it will generate a DC voltage signal output. After two conversion lines, two-wire 4 ~ 20MA output. Three features ◆ stability, full-scale, long-term stability of the zero up 0.2% FS / years. In the compensated temperature range of 0 ~ 70 ℃, the temperature drift of less than 0.2% FS, in the entire operating temperature range of less than 0.5% FS. ◆ reverse protection, current limiting protection circuit, reversed polarity installation will not damage the transmitter, the transmitter will automatically abnormal limiting in less than 35MA. ◆ Solid-state structure, no moving parts, high reliability, long life ◆ From the air pressure to the water, the oil can be highly accurate measurements, not measured media quality size. ◆ Easy to install, simple structure, economical and durable.
