GE德鲁克(Druck) PTX 120 WL 湿湿差压传感器

P TX 12 0 / W L P T X 1 2 0 / W L Wet/Wet Differential Pressure Transmitter ! ±0.1% B.S.L. for ranges to 500 psi ! Encapsulated electronics !! Zero and span trim controls !! Intrinsically safe as standard ! ±1.5% total error band -20° to +80°C ! Two wire, 4-20mA The PTX 120/WL is a truly “wet/wet” differential pressure transmitter of accepting a wide variety of pressure media on each port. The positive (high pressure) port is a fully welded 316 stainless steel assembly, the negative (low pressure) port contains stainless steel, silicon, glass, epoxy, aluminum and a silicon ‘o’ ring seal. The two pressure ports act upon a piezoresistive bridge diffused into a silicon diaphragm, which provides high overload capabilities together with excellent linearity, hysteresis performance and fast response. Integral two-wire electronics provide excitation and conditioning of the bridge signal to generate a 4-20mA output including fine trim potentiometers for zero and span adjustment. A fully welded case assembly is completed with an integral cable or a mounting block which includes a plug and socket electrical connector. Many options are available including units with dual isolating diaphragms to provide metallic media compatibility on both ports, fully submersible units, and hermetic designs incorporating a welded plug and socket electrical connector.
