specifications features data sheet mar. 15, 1999 date fha, fka ... 3 fcx ?ax series EDSX5-71 the fcx ax 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 specifications type: model fha: 4 to 20ma model fka: 4 to 20ma with digital signal service: liquid, gas, or vapour span, range, and overrange limit: remark: to minimize environmental influence, 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: model fha: 4 to 20ma dc 2-wire model fka: 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. f a 01 f a 02 f a 03 f a 04 overrange limit [mpa] {bar} type 1. high accuracy 0.2% accuracy for all calibrated spans is a standard fea- ture 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 calibra- tion ranges without additional adjustment. 2. minimum environmental influence 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. 3. replaceable communication module fuji micro-electronics manufacturing technology offers replaceable communication module that makes fcx ax transmitter very unique in design. in case of change in communication protocol, all that needs to be done is just to replace the module and the transmitter gets upgraded to the new version. 4. fuji/hart bilingual communication module the communication module is "bilingual" to speak both fuji proprietary protocol and hart. any hart compatible devices can communicate with fcx ax series transmitters. 5. application flexibility various options that render the fcx ax suitable for almost any process applications include: analog indicator at either the electronics side or ter- minal side full range of hazardous area approvals built-in rfi filter and lightning arrester ? -digits lcd meter stainless steel electronics housing wide selection of materials 6. burnout current flexibility (under scale: 3.2 to 3.8ma, over scale: 20.8 to 21.6ma) burnout signal level is adjustable using model fxw hand held communicator (hhc) to comply with namur ne43. (available for amplifier unit from version 24 and fxw(hhc) version 5.3.) 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. 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} 13 {0.13} 50 {0.5} 300 {3} 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. fha fka fha/fka 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} absolute pressure transmitter 1 2
