specifications features the fcx -a iii absolute pressure transmitter accurately measures absolute pressure and transmits a proportional 4 to 20ma signal. the transmitter utilizes a unique micromachined capaci- tance silicon sensor with state-of-the-art microprocessor tech nology to provide exceptional performance and func- tionality. functional speci cations service: liquid, gas, or vapour span, range, and overrange limit: remark: to minimize environmental in uence, span should be greater than 1/40 of the max. span in most applications. the maximum span of each sensor can be converted to different units using factors as below. 1mpa abs=10 3 kpa abs=10bar abs=10.19716kgf/cm 2 abs =145.0377psi abs 1kpa abs =10mbar abs=101.9716mmh 2 o abs =4.01463inh 2 o abs=7.50062mmhg abs output signal: 4 to 20ma dc with digital signal super- imposed 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 op- tional arrester. 1. high accuracy 0.2% accuracy for all calibrated spans is a standard feature for all ap models covering 1.6kpa {0.016bar} range to 3000kpa {30bar} high pressure range. 0.1% accuracy is available as option. fuji s micro-capacitance silicon sensor assures this accuracy for all suppressed calibration ranges without additional adjustment. 2. minimum environmental in uence the advanced floating cell design which protects the pressure sensor against changes in tempera ture, and overpressure substantially re duces total measure- ment 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 5. 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. 6. 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. absolute pressure transmitter fka 01 fka 02 fka 03 fka 04 overrange limit [mpa] {bar} type 0.5 {5} 0.5 {5} 1. 5 {15} 9 {90} min. range limit [kpa abs] {bar abs} span limit [kpa abs] {bar abs} 1. 6 {0.016} 1. 6 {0.016} 5 {0.05} 30 {0.3} 16 {0.16} 130 {1.3} 500 {5} 3000 {30} max. 0 to +16 {0 to +0.16} 0 to +130 {0 to +1.3} 0 to +500 {0 to +5} 0 to +3000 {0 to +30} data sheet fka ... 5 date EDSX5-91H aug. 10, 2011 [ l-type ] [ t-type ]
