Ethernet added to Emerson Coriolis meter

J943 coriolisAdditionally, the transmitter incorporates a configurable I/O channel, which can be used as a discrete input or set to a mA, frequency or discrete output. This enables powerful application options with minimal equipment. For example, the discrete input can be used as a totaliser reset, the discrete output can control a valve in conjunction with the integrated batch control software, the frequency output enables a quick connection for proving applications, or the mA output can be used to tie into existing or legacy control systems.

The Ethernet upgrade is available with multiple protocol choices including EtherNet/IP, Modbus TCP, and Profinet.

To speed integration and connection with Ethernet/IP systems, the transmitter contains an EDS (electronic data sheet) file for fast access to instrument information with little to no manual setup. This also enables automatic AOP (add-on profile) generation for quick and powerful system integration. Pre-configured input assemblies allow users to select exactly what is needed from a wealth of information in a Coriolis meter, without burdening the network with unwanted traffic.

“The Micro Motion Model 5700 Coriolis transmitter has delivered proven value and unique differentiation to users. The rugged housing is certified for tough field environments, including extensive hazardous area certifications and approvals. The housing was engineered to provide easy access for installation, mounting, and maintenance,” said Jason Leapley, product manager. “Now, with the option for native Ethernet, users can easily access process information without going out to the instrument.” readers will be aware that Endress+Hauser has used Ethernet on their Coriolis meters since the 2011 Rockwell Automation Fair: their unit was launched in about 2010.



New ABB inverter boosts solar performance

The new ABB PVS980 central inverter – an essential component in every solar installation that converts direct current (DC) produced in solar panels into alternating current (AC) for use by electricity grids – allows the amount of incoming solar power connected to a single inverter to be increased by as much as 40%: a dramatic improvement that completely changes the economics of a solar installation. Thanks to its increased power, the PVS980 inverter also means a site needs 30% fewer inverters than previously.

The PVS980 high power 1500 VDC central inverter is capable of processing more incoming DC power from photovoltaic (PV) panels through one inverter, reducing the total number of inverters needed on-site, which helps reduce overall costs across the lifetime of a solar plant. Central inverters are used for applications such as large field installations as well as large arrays installed on buildings and industrial facilities. Originally introduced at the Intersolar exhibition as a concept last year, the PVS980 is now shipping commercially and has already seen strong interest among customers, with a number of pilot projects in place. The new inverter is designed to seamlessly integrate into digital smart grids and operate efficiently, while reducing the carbon footprint of the installation.

ABB engineers have improved the compactness of the device, enabling a power density increase of more than 40% – making it possible to build large power rated inverters in the same physical size. Avoiding external air entering the critical compartments of the inverter, the equipment can operate from below freezing to extreme heat in 100% humidity without jeopardizing functionality. The very wide temperature capability offers full performance without derating at up to 50°C, in a waterproof and dustproof enclosure.
