1.Descreption

    FOUNDATION Fieldbus is the digital communication line for the field instruments, whose signal is internationally standardized by Fieldbus Foundation. The Fieldbus bi-directional digital communication performance makes possible for the field instruments and the control devices to be a complete on-line system, superseding the existing analog transmission lines. Thus, based on FOUNDATION Fieldbus specifications, AXF Fieldbus models offer more flexible instrumentation through a higher level communication capability and propose the cost reduction by multi-drop wirings with less cables

2.Features

    ● Interoperability FOUNDATION Fieldbus specifications grant the interoperability of the field instruments without preparing designated softwares for the instrument. 

    ● Reduction of instrumentation cost The multi-drop wiring on the Fieldbus communication line contributes to the reduction of wiring cost. 

    ● Function blocks Discrete Input (DI), Integrator (IT), Arithmetic (AR) function blocks are available as standard function besides Analog Input (AI) function block. Proportional/ Integral/Derivative (PID) function block is also supported as an option. 

    ● User Friendly Fluid Adhesion Level Diagnosis By constantly monitoring the level of insulating substance on the electrodes, it is possible to determine when maintenance is required. With the utilization of a replaceable electrode type flowtube, in case of severe adhesion, the electrodes can be easily removed from the meter and cleaned. Clear and Versatile Indications The LCD indicator employs a large, backlit full dotmatrix, that can facilitate various displays. One to three lines of indications are possible. When there is an alarm condition, a full description of the countermeasures is indicated. 

    ● Link master function AXF Fieldbus models support the Link Maser function. This function enables backup of network manager and local control only by field devices. 

    ● Self-diagnostic function The reliable self-diagnostic function detects various system alarms, process alarms and setting alarms. 

    ● Expansion of Product Lineup Two Types of Accuracy Standard accuracy is ±0.35% of Rate, and High grade accuracy type (±0.2% of Rate) is also available. 

    ● Enhanced Performance and Specifications Enhanced Dual Frequency Excitation Method The “Enhanced Dual Frequency Excitation Method” can be optionally selected. For severe applications such as for high concentration slurry or low conductivity fluid, extremely stable measurements can be realized. Improved Minimum Conductivity The lower limit of conductivity is from 1µS/cm.
