Endress+Hauser launches two analysers for the power market
E
ndress+Hauser has launched two analysers for power industry applications: the CA76NA monitors sodium, while the CA80SI analyzes for silica in boiler feedwater, steam, condensate and ion exchangers. Each analyser can accept up to six sampling inputs.
The CA76NA potentiometric analyser
measures the concentration of dissolved sodium ions. An increase in sodium levels in boiler feedwater indicates the presence of unwanted dissolved impurities. This can cause corrosion, leaks, serious damage and expensive repairs. The analyser monitors the water/steam circuit in power stations, condensate systems for values indicating ruptures, demineralization systems, steam and cation systems, and mixed bed exchangers. The measurement is potentiometric using a special electrode system comprising an Na-sensitive electrode in conjunction with an Ag/AgCl reference electrode. It measures sodium over a range of 0.1 to 2000 µg/l (ppb) with accuracy and repeatabiliry of ±2%. Outputs include up to six 4-20mA channels, along with relays for alarms and warnings. The analyser is also available
with Profibus DP communications. The Liquiline System CA80SI colorimetric analyser provides precise online analysis of silica to protect plant equipment from deposits to ensure optimum performance of turbines and ion exchangers. Deposits of insoluble silicon dioxide on internal boiler walls, heat exchangers and turbine blades have an adverse effect on the efficiency of power plants and increase the risk of unplanned downtime and repairs. For this reason, the silica content in boiler feedwater must be monitored. The CA80SI measures silica concentration from 0.5 to 200 µg/l or 50 to 5 000 µg/l, each with ±2% full scale accuracy. This allows the analyzer to determine the purity of boiler feed water and steam, and to provide early warnings of condenser leaks or exhaustion of ion exchangers. Its standard heteropoly blue analysis method allows direct comparability to lab results.
Seamless integration into process
control systems is provided by Modbus, EtherNet/IP and PROFIBUS digital communication that can transmit advanced diagnostic information in addition to the measured variable.
Remote access via any device with a
web browser is provided by an optional, integral web server, enabling full and secure access to the device configuration, measured values, diagnostic messages, logbooks and service data.

DC/DC converters from RECOM in compact 1” x 1” footprint at Rutronik UK
T
he new DC/DC converter series REC15E-Z from RECOM comprises fully specified 15W devices with wide input voltage ranges. They increase flexibility by accepting several standard bus voltages. Due to their compact footprint (1” x 1”), the converters are suitable for cost sensitive applications where board space is at a premium. The REC15E-Z series is available from Rutronik UK. Without minimum load and with 1600VDC isolation and output currents up to 4A, the converters show high efficiency of up to 90 per cent and low ripple/noise. The wide 4:1 input voltage ranges accept 9-36V or 18-75V to cover multiple
supply options such as lead-acid or lithium batteries or 12/24/36/48V industrial bus voltages. The inputs are protected against transients of up to 100V. They feature undervoltage lock out (UVLO) to protect batteries from being over-discharged. The single or dual outputs are continuously protected against short circuits and overload and can drive high-capacitive loads. The REC15E-Z series covers a wide temperature range from -40°C to +75°C without derating. The converters are fully certified to industrial EMC and safety standards and come with a three- year warranty.
Densitron introduces two new WUXGA HDMI monitors
D
ensitron, provider of Human Machine Interaction (HMI) and display technology solutions
introduced 7” and 10.1” WUXGA display monitors for broadcast, control and monitoring, test and measurement, and industrial applications. Both of the monitors feature convenient HDMI connectivity, in-plane switching, high contrast, 1200x1920 resolution, improved colour saturation, a native four-lane MIPI interface, and single VDD power supply.

rutronik.com Rittal systems ideally suited to switchgear marine applications R
ittal’s systems, from housing and enclosure systems, to climate control solutions and to power distribution systems and IT infrastructure solutions, are used by maritime operators across the globe.
These include large numbers of shipyards, ships, harbours, offshore platforms and inland, with clients that include the major ships’ chandlers and shipyards. The choice of Rittal as a partner is typically driven both by the high quality of its portfolio – easily sufficient to cope with the most demanding of marine environments - and by its consistent systems approach, which extends from project planning to implementation. Just recently, Rittal’s products were
featured in the refurbishment of the Nesserland lock in Germany, which has acted as a gateway to the inland port of Emden
6 September 2019
for more than 100 years. The work included a new road bridge built over the lock for vehichles to cross which is also designed to open whenever ships need to enter the port. Power to the system was supplied via
three low-voltage switchgear systems housed in Rittal enclosures, and included NH slimline fuse-switch-disconnectors from Rittal’s RiLine busbar range. Rittal IT racks accommodate the system’s complex network technology, with its free-standing enclosures housing the complex automation and safety technology. The system at Emden is designed such that the individual functions of the lock and the bridge are networked together. As such, it requires complex automation which is essentially controlled across three different locations: the main engine room; the engine that drives the bridge and the emergency control station which sits above that.
Components in Electronics
Mark Guest, Rittal’s product manager for IT Power Distribution sais: “International maritime switchgear construction specialists are typically very loyal Rittal customers, not least because of our focus on value creation from engineering through construction to final application.
“For switchgear manufacturers, Rittal
offers a combination of high product quality and a renowned system concept, around which all our solutions are based. This extends from our range of accessories, which are quick and easy to access, to engineering tools (such as EPLAN Electric P8 and EPLAN Pro Panel) and its Perforex machining centres. “It means production times can be minimised while project leaders can react fast to any changes to the original specifications, swapping enclosures around if the project requirements change.”

director, Chris Goodhall, said, “We are launching these new displays because there is a distinct need for exceptional high-resolution and wide viewing angle displays for a number of applications that the market is not currently addressing. We are confident that these models will join the rest of our range as the best and most optically pristine high-performance displays of their size in the market.” The 7” version provides peak luminance of 450cd/m2, adjustable brightness, and includes IPS technology that provides 80/80/80/80 symmetric viewing. Similarly, the 10.1” display provides peak luminance of 600cd/m2, adjustable brightness, as well as IPS technology that provides 85/85/85/85 symmetric viewing. Both models also provide the twin benefits of optical bonding with Projected Capacitive Touch (PCT) as standard. Furthermore, both are designed to operate continuously in 24/7 mode, with a backlight half-life of 50,000 hours, which is approximately five years. Goodhall added, “Reliability and longevity are hallmarks of Densitron, which has stood for quality for more than 45 years. By continually improving processes and technologies, we are able to introduce new monitors such as these that are built to, and beyond, the industry’s highest standards.” Both new monitors are available immediately and will make their public debut at IBC 2019 in Amsterdam from 13-17 September on Stand 8.B41.
