FKH...5 Absolute pressure transmitter Liquid, gas, or vapour. Span, range, and overrange limit : ■ DATA SHEET The ProcessX absolute pressure transmitter (direct mount type) accurately measures absolute pressure and transmits proportional 4 to 20 mA signal. the transmitter utilizes the unique micromachined capacitive silicon sensor with state-of-the-art microprocessor technology to provide exceptional performance and functionality. ■ features 1. High accuracy 0.2% accuracy for all calibrated spans is the standard feature. Georgin's micro-capacitance silicon sensor assures this feature for all suppressed calibration ranges without additional adjustment. 2. Minimum inventory Electronics unit, communication module, local indicators and electronics housing are interchangeable among all ProcessX models. 3. Minimum environmental influence The "Advanced Floating Cell” design which protects the pressure sensor against changes in temperature, static pressure, and overpressure substantially reduces total measurement error in actual field applications. 4. Georgin/HART® bilingual communications protocol ProcessX series transmitter offers bilingual communications to speak both Georgin proprietary protocol and HART®. Any HART® compatible devices can communicate with ProcessX. 5. Application flexibility Various options that render the ProcessX suitable for almost any process applications include : • Analog indicator at either the electronics side or terminal side, • Full range of hazardous area approvals, • Built-in RFI filter and lightning arrester, • 5 digit LCD meter with engineering unit, • Stainless steel electronics housing, • Wide selection of materials. i Functional specifications Type : FKH : Smart, 4-20 mA DC + Georgin/Hart® digital signal Service : Output signal : 4 to 20 mA DC with digital signal superimposed on the analogic signal. Power supply : Transmitter operates on 10.5 V to 45 V DC at transmitter terminals. 10.5 V to 32 V DC for the units with optional arrester. 6. Burnout current flexibility (Under Scale: 3.2 to 4.0 mA, Over Scale: 20.0 to 22.5 mA) Burnout signal level is adjustable using Model FXW or Hand Held Communicator (HHC) to comply with NAMUR NE43. 7. Dry calibration without reference pressure Thanks to the best combination of unique construction of mechanical parts (Sensor unit) and high performance electronics circuit (Electronics unit), reliability of dry calibration without reference pressure is at equal level as wet calibration.

FKH...5 Absolute pressure transmitter Zero/span adjustment : Zero and span are adjustable either from the HHC(1) in Hart® or Georgin protocol. Zero is also adjustable externally from the adjustable screw. Damping : Adjustable from HHC(1) or local adjustment unit with LCD display. The time constant is adjustable between 0.06 to 32 sec. Zero elevation/suppression : 0 kPa abs to +100% of URL. Normal/reverse action : Selectable from HHC(1) Indication : Analog indicator or 5 digit LCD meter, as specified. An analog display may be mounted at the location of one or the other of the housing....
