EDDL ENHANCEMENTS TO SPECIALIZED ROTATING MACHINERY MONITORING TECHNOLOGY

Description

Based on enhancements to the international standard Electronic Device Description Language (EDDL), Emerson Process Management has introduced EDDL enhancements into its motor-pump monitoring technology, the CSI 9210 Machinery Health™ Transmitter. The CSI 9210 is a key member of Emerson's range of field devices and valves that power its PlantWeb® digital plant architecture to reduce capital project costs and improve operations efficiency. The CSI 9210 acquires vibration, temperature, motor flux, and machine speed on AC motor-pump machine trains, analyzes the measured data, calculates machinery health, issues alerts if necessary, and recommends action to be taken. With these recent interoperable EDDL improvements, end users now have improved access to details surrounding the analysis results, thus enabling them to make even better operational decisions. Emerson recently announced a move towards the enhanced EDDL interface for its field devices and valves, which will drive new displays that use familiar dialog boxes to present graphs, charts, and trending of dynamic variables in addition to text, and archived data in a consistent, familiar format. “EDDL enhancements lend themselves very well to the types of information people have asked to see from the CSI 9210, and Emerson is committed to delivering what our customers need,” said Brian Humes, general manager of Emerson’s Machinery Health Management business. “The new EDDL interface provides a clearer, visually-intuitive picture of developing cavitation – plus it is interoperable.” “For example, enhanced graphics can clearly show when the pump has exceed the Maintenance Threshold for cavitation, as indicated by displaying a bar graph, as well as in the graphic of the pump itself,” continued Humes. “As cavitation continues to increase, we see all three graphical elements change to reflect the pump moving into the Failed Threshold. Also, spectrum data associated with the cavitation is presented, along with recommendations for correcting the situation before actual failure occurs. Sophisticated devices with hundreds of configuration, calibration, and diagnostic parameters such as control valves, radar level gauges, and variable frequency drives will greatly benefit from the new user interface enhancements. EDDL is the only common technology endorsed by the Fieldbus Foundation, HART Communication Foundation, Profibus Nutzerorganisation e.V. (PNO), and OPC Foundation. The interoperability of the language gives users the freedom to choose best-in-class automation products from the suppliers of choice, knowing devices and hosts will work fully and seamlessly together. About EDDL

Specs

Sensor Input Details • Accelerometer AC-input channels have an input range of 10 Volts peak or 20 Volts peak peak. For an accelerometer with 0.1 V/g, the allowable input voltage corresponds to 70 g's RMS or 100g's Peak. • Sensor power for each accelerometers channel is ~22VDC @ ~3 mA. • Four temperature inputs for 10K-ohm thermistor sensors can measure from -40°C to 150°C. Data Conversion • All vibration input channels are collected simultaneously using 24 bit Sigma Delta ADCs which provide >120dB of dynamic range. The sampling rate of 102.4 kHz provides >40 kHz bandwidth.
