FKA-5 Absolute pressure transmitter Type ■ DATA SHEET The ProcessX absolute pressure transmitter accurately measures absolute pressure and transmits a proportional 4 to 20 mA signal. The transmitter utilizes a unique micromachined capacitance 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 a standard feature. 0.1% accuracy is available as option. 2. Minimum inventory and design Electronics unit, local indicators and electronics housing are interchageable among all ProcessX transmitters. 3. Minimal environmental impact The "Advanced Floating Cell" design which protects the pressure sensor against changes in temperature, and overpressure substantially reduces total measurement error in actual field applications. 4. Georgin/HART™ bilingual communication 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 : • 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. 6. Programmable output Linearization Function Output signal can be freely programmable. (Up to 14 compensated points at approximation). 7. 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. Functional specifications Type : FKA : Smart, 4-20 mA DC + Georgin/Hart® digital signal Service : Liquid, gas or vapour Span, range, and overrange Hmrt : Remark : To minimize environmental influence, span should be greater than 1/40 of the max. span in most applications. 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 the units with optional arrester. FC-FKA-EN-24-07-2017 Subject to modification due to technical advances 8. 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.
