MLX Loop-powered indicators
Loop-powered indicators provide a local display of a sensor’s measured value. The MLX loop-powered indicator operates from a 4–20-mA DC input, and its NEMA 4X aluminum housing meets Factory Mutual (FM) explosionproof requirements. It includes a six-digit numerical LCD display, a six-digit alphanumeric display for engineering units, and a 20-segment bar graph that indicates 0–100% of full scale. Stainless steel tags and epoxy resin or polyurethane-epoxy paint coatings are available.

Admag AXF Magnetic Flowmeter
Retaining all the features and functions of earlier Admag flowmeters, the Admag AXF magnetic flowmeter offers new diagnostics to detect electrode coating. By constantly monitoring the change in the impedance of the electrode circuit due to the build-up of insulating coatings, the AXF converter will display four different levels of coating and provide an alarm function. Optional replaceable electrodes make maintenance and cleaning easier, because the user can rely on the new predictive diagnostics to monitor the status of the electrodes and then remove them for cleaning when necessary.

The UT551 Digital Indicating Controller
The UT551 digital indicating controller allows users to acquire temperature, pressure and flowrate data and to make changes to controller settings via an Ethernet connection. It employs the Modbus/TCP protocol and is equipped with a 10BASE-T interface. A gateway function allows a PC or other host system to access non-Ethernet-enabled indicating controllers or peripheral devices by simply connecting them to the UT551.

AAASuite alarm-management system
Yokogawa has released a new upgrade to its Advanced Alarm Administrator (AAASuite, Version R1.20). AAASuite is a comprehensive alarm-management system that improves operator performance by minimizing nuisance alarms and providing timely notification of only necessary alarms, thereby preventing alarm flooding and enabling safe, stable and cost-effective plant operations. Version R1.20 includes an optional static alarm suppression function that facilitates equipment-based simultaneous suppression of alarms at start-up, shutdown, or upset of a plant. AAASuite R1.20 also enables the unlimited use of Yokogawa legacy controllers, which makes it suitable for systems that combine the CENTUM V, XL, and CS controllers.

ToughMeter Series 270
ToughMeter Series 270 analog panel meters are designed to withstand harsh environments. They are available in 2.5-in. and 3.5-in. models, and have an accuracy of 2% DC and 3% AC. The meters have all-metal cases and polycarbonate windows, gasket-sealed bezels, terminals, and zero regulators that ensure dust and moisture protection to International Protection (IP) 66 code. They are available with either pivot and jewel or taut band suspension.
