Supply pressure transmitter can be none other non-calibration priced

WMF-2000 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. 1KPA ~ 100KPA 385 yuan / 0 ~ 100PA 810 yuan / 0 ~ 500PA 810 yuan / 0 ~ 800PA 810 yuan / only good features ◆ stability, full-scale, long-term stability of zero up to 0.2% FS / Year . 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: -100Pa ~ 0-200KPa 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 medium: 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 ~ 70 ℃ structural characteristics of housing: die-cast aluminum alloy body structural materials : 1Cr18Ni9Ti Pressure port: Ф8 pagoda mouth weight: 0.5Kg debugging method according to label instructions, see the zero and full scale resistance, external standard power supply and ammeter (0.2 pole above), you can adjust the steps include: ◆ in pressure transmitter is not the case, adjust the zero resistors, so that the output current of 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. Notes ◆ who supply products with the use of manual and certification, including product number, technical parameters, date, please check carefully to avoid the wrong. ◆ unavailable hard object squeeze the transmitter diaphragm directly, so as not to damage the transmitter. ◆ should be installed according to the product type and threaded connections, check the site interface is consistent with the product interfaces, should be connected to a slow tightening, the torque can not be directly applied to the transmitter housing, only added to the pressure port On the six-party. ◆ connected power supply should be strictly in accordance with our wiring to connect. ◆ edge transmitter overload pressure should not exceed 200% of the range. ◆ abnormal use, turn off the power to stop using checks, or directly to our technical department. ◆ transport, storage should restore the original packaging and store in a cool, dry, ventilated warehouse.
