specifications features data sheet date fhk, fkk fcx ?c series the fcx ? differential pressure transmitter accurately measures differential pressure, liquid level or gauge pressure and transmits proportional 4 to 20ma signal. the transmitter utilizes the unique micromachined capacitive silicon sensor with state-of-the-art microprocessor technology to provide exceptional performance and functionality. EDSX6-104 feb. 2, 1999 1. high accuracy 0.1% accuracy for all calibrated spans is the standard feature covering 0.6kpa {60mbar} draft range to 2000kpa {20bar} high differential. fuji's micro-capacitance silicon sensor assures this feature for all elevated or suppressed calibration ranges without additional adjustment. 2. minimum inventory electronics unit, communication module, local indicators and electronics housing are interchangeable among all fcx ? models. process cover including bolts and nuts are common for all dp and flow transmitters, rating 3.2 and 14mpa (32 and 140 bar). 3. replaceable communication module fuji micro-electronics manufacturing technology offers replaceable communication module that makes fcx-a/ c transmitter very unique design. in case of change in communication protocol all that needs to be done is just 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-a/c series trans- mitters. 5. application flexibility example features that render the fcx ? suitable for almost any process applications includes. analog indicator at either the electronics side or terminal side full range of hazardous location approvals built-in rfi filter and lightning arrester ? -digits lcd meter functional specifications type: model fhk: 4 to 20ma model fkk: 4 to 20ma with digital signal service: liquid, gas, or vapour static pressure, span, and range limit: type static pressure [mpa] {bar} range limit [kpa] {mbar} span limit [kpa] {mbar} max. min. ?.1 to + 3.2 {? to + 32 } ?.1 to + 14 {? to + 140 } ?.1 to + 14 {? to + 140 } ?.1 to + 14 {? to + 140 } ?.1 to + 14 {? to + 140 } f k 12 f k 33 f k 35 f k 36 f k 37 +/ 6 { +/ 60 } +/ 32 { +/ 320 } +/ 130 { +/ 1300 } +/ 500 { +/ 5000 } +/ 2000 { +/ 20000 } 0.6 {6} 3.2 {32} 13 { 130 } 50 { 500 } 200 {2000} 6 {60} 32 { 320 } 130 { 1300 } 500 { 5000 } 2000 { 20000 } 0.375 { 3.75 } 2 {20} 8.125 { 81.25 } 31.25 { 312.5} 125 {1250 } fhk fkk fhk/fkk differential pressure transmitter 1 2
