Reliable Performance and Compactness (ISO 9001 Facility)

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. Manufacturing quality control complied with ISO 9001 ensures FCX-AII transmitter's long-term stablity and reliability.

Unique Technology		Dual Temperature Sensors In addition to the temperature sensor in the sensor unit, one more temperature sensor is put in the electronics unit. Temperature errors occurred in the sensor unit and the electronics unit are corrected by the data of each temperature sensor in each unit, thereby the temperature characteristic of transmitter is distinctly enhanced.
FCX-AII Series transmitter is smart type transmitter equipped with communication function as a standard. Fuji and HART(Highway Addressable Remote Transductor) protocol are supported on FCX-AII Series transmitter. Remote setting/display is possible by using Fuji's Hand Held Communicator (HHC) or HART compatible HHC.

Dead time of FCX-AII Series transmitter is approximately 200msec, that is smaller compared to our previous model FCX-A, which has approximately 300msec. Dead time of 40msec (update rate=25times/sec) is available as an option.

ASIC Technology New original ASIC in which digital and analog circuits are mounted jointly is developed by making free use of forefront microelectronics design technique. FCX-AII Series adopts this ASIC to detect the electrical capacitance of the sensor. This new ASIC allows stable and accurate analog/digital conversion, thereby considerably improves the long term stability and reliabilities.

Micro capacitance silicone sensor The technological centerpiece of the FCX-AII Series is a Fuji micro-capacitance silicon sensor with improved S/N ratio. It was specifically designed to raise the output in electrical capacitance caused by changing input pressures. As a measuring diaphragm material, the sensor uses a single crystal silicon that has little hysteresis and material fatigue. The result is remarkable improvement in temperature characteristics and stability.

Full Interchangeability Both Electronics unit and Sensor unit are fully interchangeable as individual configuration data of both units are stored separately at each own EEPROM. The electronics unit is also interchangeable over the entire range of FCX-AII models, including differential pressure type, pressure type, absolute pressure type, level remote seal type, and others.
