Temperature pressure level transmitter

Products WMB-HSGW-01 WMB Pressure (level) 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. ◆ reverse protection, current limiting protection circuit, the installation of positive and negative reversed will not damage the transmitter, the transmitter will automatically limit the abnormal 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: -100KPa ~ 0-60MPa Maximum Overload: 2 times standard range of pressure form: gauge pressure, differential pressure Accuracy class: 0.25% FS 0.5% FS Power supply voltage: 24VDC Load Resistance: ≤500Ω measuring media : steam pressure or gas, liquid long-term stability: ± 0.2% FS / Environmental Relative Humidity: 0 to 95% to compensate for temperature: 0 ~ 70 ℃ Operating Temperature: -10 ~ 70 ℃ (high temperature to be ordered, can be customized, up to 1000 degrees) Features: Shell: The main structure of all stainless steel body material: 31618Cr-12Ni-2.5Mo Pressure connection: M20 × 1.5 or user-defined weight: Normal 1kg, 1.2kg debugging methods with head type table: Open ◆ no pressure in the case of the transmitter: HSM joints, unscrew the stainless steel tube, you can see the zero and full scale resistance, external standard power supply and ammeter (0.2 pole above) can be adjusted, as follows By adjusting 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; ◆ adjustment is completed, Tighten the protective cover. ◆ Where products are supplied with instructions 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. ◆ 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. ◆ replacement year. Electrical Connection: 1: current output: Open Hirschmann connector, the 3rd termination power positive, negative ground termination power 2: voltage output: Open Hirschmann connector, the 3rd termination power positive, negative ground termination power, the 1st end contact voltage output. 3: If the cable output, then the power blue positive, then the power of color were negative.
