You never have to worry again about losing critical temperature measurements because of a sensor failure thanks to the new THZ3 and TDZ3 Smart HART® Dual Input Temperature Transmitters from Moore Industries. With two inputs, users can select one as a backup in case there is a failure with the primary sensor. If there is a problem with the main sensor, the transmitter automatically switches to the backup sensor.

Failure protection is just one key feature of the new dual input THZ3 and TDZ3. Other features include:

• Average and differential measurement: Average the readings from two sensors in tanks where stratification can occur. Use the differential measurement capability to monitor the temperature delta across a heat exchanger for efficiency or BTU calculations.
• High-Select and Low-Select: Use two sensors and select the higher or lower one as a basis for control. High-Select and Low-Select enables you to reduce the chance of an over-temperature or under-temperature situation.

The THZ3 and TDZ3 also come with Device Intelligence, a series of features for smarter control and monitoring including:

• Sensor drift and corrosion detection that checks and alerts users when the sensor is drifting out of a preset range or when the resistance due to corrosion exceeds set parameters.
• Smart range alarms with four HART alarms – set to any input or calculated input – that detect when the variable is within or outside of user preset limits.
• A High Availability option that enables the selection of how the AO behaves when there is an input failure or out-of-range value detected by the transmitter. By utilizing the input simulation feature, users can manually input a digital input signal that allows the testing of the AO and any HART or diagnostic alarm.

The launch of the Rotork CQ Compact introduces a range of fully concentric, balanced design pneumatic and hydraulic valve actuators that deliver a reliable and efficient self-contained solution for applications demanding functional integrity and safety where space is limited.

In addition to providing reduced dimensions when compared with conventional scotch-yoke actuators, the CQ’s symmetric design also presents a perfect weight balance on the valve, enabling increased efficiency for assembly and disassembly. The totally enclosed, rugged CQ weatherproof housing contains a helical mechanism which transforms linear piston motion into 90º (+/-5º) rotation for the operation of quarter-turn valves. As an option, rotation can be increased to 180º. Complete customisation of the torque profile is available to suit individual valve requirements.

The CQ range features a choice of cylinder sizes and different actuator builds for many diverse applications. In all cases the CQ design incorporates the removable valve adaptation within the overall dimensions for maximum compactness and actuators can be easily and safely disassembled to access internal parts for field maintenance. Internal coatings provide enhanced corrosion protection for long term reliability. External epoxy finishes and a wide choice of seal materials can be specified to meet industry and customer requirements.

CQ Compact actuators are available for single or double-acting operation with output torques up to 600,000 Nm. Pneumatic operation is available using instrument air, nitrogen or clean natural gas at 12 barg pressure, whilst 210 barg is recommended for hydraulic operation. Environmental and hazardous area certifications include IP66M/IP68M, PED, ATEX, IECEx and GOST. The actuators are also suitable for SIL3 safety related duty.

The standard operating temperature range is -30ºC to +100ºC providing suitability for applications in harsh and challenging environments, with an optional low temperature limit of -60ºC.

Cobham Wireless, formerly the Wireless Test Business of Aeroflex, and NI (Nasdaq: NATI), the provider of platform-based systems that enable engineers and scientists to solve the world’s greatest engineering challenges, today announced a worldwide partnership to service applications in cellular and connectivity with solutions based on PXI technology.

Under the terms of the agreement, NI acquires the existing Cobham PXI modular instruments hardware product line and becomes Cobham’s primary provider of PXI technology. The acquired PXI modular instruments will be manufactured by NI and supplied exclusively to Cobham for sale through the Cobham Wireless business unit’s direct sales channels and brand, which will ensure continuity and continued support for existing PXI-based customers. The companies will also collaborate to incorporate the latest NI PXI modular instruments, including the NI vector signal transceiver with LabVIEW FPGA, into Cobham’s next-generation cellular and connectivity test systems.

With the agreement, Cobham Wireless will become the NI Global Preferred Partner for Cellular and Connectivity Applications, part of the NI Alliance Partner Network.

“We are excited to partner with Cobham,” said Pete Zogas, senior vice president of Segments and Services at NI. “As wireless industry leaders, they have the resources necessary to provide solutions and services on a global scale. Our customers will benefit greatly from the combination of the NI platform and Cobham’s unique domain-specific expertise within the cellular and connectivity application space.”

Ian Langley, senior vice president and general manager of the Cobham Wireless Business Unit, said, “With increased test complexity and faster design cycles, we chose to build our RF and wireless test systems based on NI’s industry-leading PXI modular instrumentation technology. The combination of LabVIEW FPGA and the NI vector signal transceiver enables us to deliver products and solutions to our customers with optimum performance and the lowest cost of test.”

Companies testing the cellular and connectivity capabilities of their products are increasingly transitioning to a software-defined modular approach using PXI to lower test costs, shorten test times and provide flexibility to adapt to changing test requirements. Because of the partnership between Cobham and NI, customers will benefit from the expertise, reputation and support of Cobham in cellular and connectivity test applications with systems based on modular instrumentation from NI, the world leader in PXI.

Rotork Midland introduces SMART-LOC, a new high integrity modular concept for pneumatic actuator control assemblies. Constructed in 316L stainless steel, the SMART-LOC system is particularly suitable for the control and sequencing of process valve actuators in oil and gas applications.

Compared to traditional fabricated panel mounted assemblies SMART-LOC offers a lighter, stronger and more compact alternative, together with significant capital and operating cost savings. Complex, labour intensive arrangements using panels, pipes and additional fittings are eliminated and replaced with a fully assembled and tested interface block, ready to be fitted directly to the actuator. Delivering best in class flow characteristics, the units will interface with all types of pneumatic actuators.

A range of field proven components – valves (spool, poppet or direct mounting) and filter regulators – connected in series on the interface, are tailored to meet the requirements of individual projects, ranging from standard shut-off circuits to intricate control circuits. The unique SMART-LOC clamping system for individual components incorporates static O-rings for higher integrity and long term reliability. No design work is required from the contractor and all components are kept in stock, resulting in very short lead times. With ATEX approval, SMART-LOC components are suitable for hazardous areas and industrial use.

The integral SMART-LOC clamping system also simplifies field maintenance, enabling individual components to be simply and swiftly unclamped and replaced.

SMART-LOC is designed with the benefit of more than 50 years’ experience in the manufacture of stainless steel pneumatic components, during which time Rotork Midland has developed a range of field proven specialist products that are renowned for their performance and reliability.
