Rotork Process Controls has launched a new range of compact, robust and reliable electric actuators for control valves, regulators and other continuous modulating applications. The CMA (Compact Modulating Actuator) extends the scope of Rotork’s proven technologies and the benefits inherent in the innovative Rotork CVA electric control valve actuator range. The CMA range increases the areas of flow control that can take advantage of these advanced features.
The Rotork CMA is available in linear, quarter-turn and multi-turn versions and a range of five compact sizes, facilitating the economical operation of numerous types of control valve, damper and pump stroke adjuster applications. Single-phase or DC electrical power supply is all that is required for control valve actuation, saving the on-going costs associated with the operation and maintenance of instrument air supplies.
The maintenance-free CMA drive train, permanently lubricated and protected in an IP67 watertight and, where required, explosionproof enclosure, can be mounted in any orientation. Accepting an industry-standard 4 -20mA command signal, the CMA delivers accurate and repeatable positional control. Resolution is 0.25% on linear and quarter-turn applications and 2 degrees on the multi-turn configuration.
Continuous and unrestricted modulating performance is provided by a brushless DC motor, magnetic contactless sensors and a lubricated for life drive train.

Doha, Qatar, 7 May 2012 – Qatar Petroleum and Total today signed a research and technology project agreement on carbonates acid stimulation.
The MC-RTU flow analyzer provides continuous digital display of flow rate and total flow of liquids or gases. When combined with a NUFLO Turbine flow meter, selected for a particular application, the MC-RTU becomes an accurate flow rate meter and flow totalizer. Low power microprocessor technology provides the MC-RTU with long life and reliability. Easily programmable using the front four-wide keypad, the MC-RTU can be programmed to display a wide variety of total flow and flow rate volumetric units. Two types of packaging and mounting options are available to suit many different applications including outdoor and hazardous locations.
The new Beckhoff CP2xxx and CP3xxx Control Panel and Panel PC series feature integrated modern display technology such as multi-touch and widescreen formats. The product development also took into account conventional operating concepts, in order to cover the widest possible range of applications. The result is a highly versatile and modular panel system, leaving little to be desired in terms of format, function, size and model variety.

National Instrumentsrecently announced the NI PXIe-4357 RTD module, the latest addition to its SC Express sensor measurement family for PXI Express. The high-performance module is optimized for temperature measurements with Pt100 RTD sensors for a variety of thermal monitoring applications. The NI PXIe-4357 module integrates sensor-specific signal conditioning with 24-bit ADCs to sample all 20 channels at 100 S/s and offers typical accuracies of up to 0.09 degrees Celsius. To expand a system’s channel count, engineers can integrate additional NI PXIe-4357 modules or use other SC Express modules to add complementary sensor inputs including thermocouples, strain gages, accelerometers and FBG optical sensors to the same system.
SNC-Lavalin (TSX: SNC) is pleased to announce that, following an open and competitive process, it has been awarded a contract by AltaLink L.P. to provide engineering, procurement and construction (EPC) for portions of upcoming transmission infrastructure projects in Alberta.
