Supply diffused silicon pressure transmitter factory direct Recruitment Agents

Products WMB2088 pressure transmitter chip imports of selected pressure 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 produce a linear output signal proportional to the applied pressure. We add a DC power supply in Wheatstone bridge, it will generate an output DC voltage signal. After two conversion lines, two-wire 4 ~ 20MA output. Specifications quote undefined Features: Good ◆ stability, full-scale, long-term stability of zero up to 0.2% FS / years. The compensated temperature range of 0 ~ 70 ℃, the temperature drift of less than 0.2% FS, over the entire operating temperature range of less than 0.5% FS. Has a reverse protection, current limiting protection circuit, the installation of positive and negative reversed will 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, high-precision measurement can be carried out, the quality is not affected by the size of the measured medium. ◆ easy to install, simple, economical and durable. The main technical parameters: Measuring range: 0-10KPa ~ 0-40MPa Maximum Overload: 2 times standard range of pressure form: gauge pressure, differential pressure Accuracy class: 0.5% F · S Power supply voltage: 24VDC Load Resistance: ≤500Ω measuring media : steam pressure or gas, liquid long-term stability: ± 0.2% F · S / Year Relative Humidity: 0 to 95% to compensate for temperature: 0 ~ 70 ℃ Operating Temperature: -10 ~ 150 ℃ (up to do 700 ℃ / need customized) Features: Housing: die-cast aluminum alloy body structural materials: 1Cr18Ni9Ti Pressure connection: M20 × 1.5 or user-defined weight: Normal 1kg, 1.2kg head type table with debugging methods: Remove the cover, that you can see the zero and full scale resistance, external standard power supply and ammeter (0.2 pole above), you can adjust the steps include: ◆ In the case of the transmitter is not pressurized, adjust the zero resistor so that Output current 4mA; ◆ transmitter pressurized to full scale, adjust the full range resistor, so that the output current of 20mA; ◆ repeat the above steps two or three times until the signal is normal; ◆ has been adjusted, tighten the protection cap.
