1. Description

    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 it possible for the field instruments and the control devices to be a complete online 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 wiring with fewer cables

2. Features

    â— Interoperability FOUNDATION Fieldbus specifications grant the interoperability of the field instruments without preparing designated software for the instrument. 

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

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

    â— 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 dot matrix 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. 

    â— Link master function AXF Fieldbus models support the Link Master function. This function enables backup of the network manager and local control only by field devices. 

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

    â— 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. 

    â— 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.
