The STEGO line of enclosure filter fans and exhaust grilles provides an optimum climate in enclosures. By channeling outside air into the enclosure, the interior temperature is reduced and heated internal air is expelled, preventing localized heat pockets and protecting electronic components from overheating. STEGO low-noise filter fans are available in 120 VAC or 24 VDC models; available sizes range from 12 to 373 CFM. Starting at $68.00 , all models are impact resistant and feature easy filter change. Outdoor models are weather/UV resistant and fitted with a lockable door. Exhaust grilles, starting at $15.50 , feature no-screw installation and are available in indoor and outdoor models. A lockable general-purpose protective cover is priced at $37.00 . All STEGO filter fans are CE and RoHS compliant and are backed with a one-year warranty.
ProSense® MPS25 series mechanical pressure switches are designed for the toughest applications where conventional pressure switches are inadequate. Starting at $82.00 , these cost-effective switches feature an all welded 316 stainless steel sealed diaphragm actuator or a direct-acting 316 stainless steel piston design. The rugged 316 stainless steel housing provides reliable operation over a wide operating temperature range. Pressure ranges from vacuum to 7500 psig are available; all models include a 1/4-inch NPT process connection and a precision snap-acting SPDT mechanically-operated switch output. Mechanical pressure switches are available with an integral six-foot cable or a DIN 175301-803C L-connector. ProSense mechanical pressure switches are UL, CSA, CE and RoHS compliant and are backed with a three-year warranty.
In a world of communication and competition, automation networks now shoulder a growing workload of multiple services in increasingly complex network environments. To succeed, networks need to improve operational and cost efficiency in order to achieve cross-system collaboration and integration that consolidates industrial Ethernet devices, fieldbus devices, and other subsystems into one highly available and coordinated network.
Automation systems can overcome these new challenges with Moxa’s industrial Ethernet solutions, an optimized industrial Ethernet portfolio that seamlessly blends wired and wireless connectivity with full edge-to-core network capability and fast self-healing redundancy to realize true automation network convergence.
By installing eWON industrial-grade Ethernet routers, Thames Water, the UK's largest water and wastewater services provider (14 million customers and 4,500 employees) is able to remotely monitor and control critical assets located at its water pumping stations and sewage treatment works across the UK.
More than 1000 eWON routers were installed up to date across a similar number of 'high priority' sites in the UK, in conjunction with a PLC/RTU device, to monitor and control site processes. The role of the eWON device is to provide secure, resilient, remote-access through the Internet, to the PLC/RTU devices on site, using a combination of both Broadband ADSL and GPRS/3G.
Jim Grandison, Workstream Lead for the SCADA Delivery Program at Thames Water comments: “As a business, we want to change the way we monitor and control our remote assets. This means moving from our existing IT communications infrastructure based on traditional technologies – a mixture of dial-up leased lines, ISDN, packet-switching, Telex and other legacy communications equipment – to what we call a near-real time approach. This project is part of our £4.9bn investment programme between 2010 and 2015 to improve our water and sewage networks”
Yvan Rudzinski, Sales Channel Manager at eWON sa, puts it: “Thames Water is one of our top reference in the utility business, water and wastewater market. Deployment keeps going on and we are very satisfied of this success. It is a state of the art application using very advanced features of our routers, such as fail-over from ADSL to GPRS, complex scripting, real time polling of data into a wide range and brands of PLCs, etc ... Our market share in the utility segment is growing and I am even more excited for the future, as we will release a new range of products end of the year, especially designed to fit this market and its various requirements.”
Thames Water operates and maintains 100 water treatment works, 30 raw water reservoirs, 288 pumping stations and 235 clean water service reservoirs. On the sewerage side of the business, Thames Water operates and maintains 350 sewage treatment works and 2,530 pumping stations.
The ‘eWON’ range of VPN routers has been specifically designed for industrial use, in order that it can intelligently interface with a wide range of automation and control devices, including all major PLCs brands, instruments, data-loggers, Modbus controllers, as well as 4 legacy serial devices.
Company MAC Solutions, eWON distributor in the UK, is supervising this project since its start in 2010.

The Flowline Ultrasonic Liquid Level Sensors are cost-effective sensors that can be usedfor small to medium capacity tanks. The product supports continuous level measurementmodels in ranges up to 9.8 ft (3m), 18 ft (5.5m), 26.2 ft (8m) or 32.8 ft (10m). They areideal for open or enclosed tanks but not suitable for pressurized tanks. The liquid sensorsare non-contact sensors making them ideal for corrosive, sticky or dirty liquids. ThisTechCorner will go through how to configure the Flowline EchoSonic II LU series liquidlevel transmitters, LU23-00.

FSD series flow switches monitor liquid media to provide reliable flow detection and are ideal for applications with rapid temperature changes or where fast response time is required, such as machine tool coolant flow, HVAC cooling water flow, and injection molding cooling water flow. FSD series switches monitor 0.26 to 6.6 GPM or 1.32 to 26.4 GPM with a fast response time of 10ms. The switches operate on 24 VDC and provide normally-open DC PNP outputs. Desired setpoints can easily be set with the rotating dial and locked with a set screw. Valve bodies are constructed of nickel-plated brass with 3/4-inch or one-inch NPT connections. The flow switches have a 4-pin M12 quick disconnect and LED output status indication. ProSense FSD series flow switches are IP65 and IP67 rated and have a two-year warranty. Prices start at $125.00.Complete Flow Switches Overview
