level transmitter the fcx -a iii level transmitter accurately measures liq uid level and transmits a proportional 4 to 20ma signal. the trans- mitter utilizes a unique micromachined capacitance silicon sensor with state-of-the-art microprocessor tech nology to provide exceptional performance and functionality. 1. high accuracy 0.2% accuracy for all calibrated spans is a standard feature for all models covering 0.32kpa {3.2mbar} range to 500kpa {5bar} high differential pressure range. 0.1% accuracy is available as option. fuji?s micro-capacitance silicon sensor assures this accuracy for all elevated or suppressed calibra tion ranges without additional adjust- ment. 2. minimum environmental in uence the ?advanced floating cell? design which protects the pressure sensor against changes in tempera ture, static pressure, and overpressure substantially re duces total measurement error in actual ? eld applications. 3. fuji/hart bilingual communications protocol fcx -a iii series transmitter offers bilingual communica- tions to speak both fuji proprietary protocol and hart ? . any hart ? compatible devices can communicate with fcx -a iii . 4. application exibility various options that render the fcx -a iii suitable for almost any process applications include: ? full range of hazardous area approvals ? built-in rfi ? lter and lightning arrester ? 5-digit lcd meter with engineering unit ? stainless steel electronics housing ? wide selection of materials ? high temperature, high vacuum service. 5. programmable output linearization function output signal can be freely programmable. (up to 14 compensated points at approximation.) 6. burnout current exibility (under scale: 3.2 to 4.0ma, over scale: 20.0 to 22.5ma) burnout signal level is adjustable using model fxw 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. data sheet fke ... 5 date EDSX7-66H aug. 10, 2011 features specifications functional speci cations service: liquid, gas, or vapour static pressure, span, and range limit: remark: to minimize environmental in? uence, span should be greater than 1 /40 of the max. span in most applications. ? lower limit of static pressure (vacuum limit) ; silicone ? ll sensor: see fig.1 fluorinated ? ll sensor: 66kpa abs (500mmhg abs) at temperature below 60 c. ? the maximum span of each sensor can be converted to different units using factors as below. 1mpa=10 3 kpa=10bar=10.19716kgf/cm 2 =145.0377psi 1kpa=10mbar=101.9716mmh 2 o=4.01463inh 2 o overrange limit: to maximum static pressure limit output signal: 4 to 20ma dc with digital signal superim- posed on the 4 to 20ma signal power supply: transmitter operates on 10.5v to 45v dc at transmitter terminals. 10.5v to 32v dc for the units with optional arrester. range limit [kpa] {m bar} fke 3 fke 5 fke 6 type span limit [kpa] {m bar} +/? 32 { +/? 320} +/? 130 { +/? 1300} +/? 500 { +/? 5000} max. 0.32 {3.2} 1.3 {13} 5 {50} min. static pressure ? ? ? 32 {320} 130 {1300} 500 {5000} up to ? ange rating
