Meggitt offers HART-enabled vibration sensors
Meggitt's PCH420V vibration sensor has a programmable transmitter that allows vibration data to be accessed by HART enabled process controllers.
Meggitt's PCH420V is the first HART®-enabled piezo-electric vibration sensor enabling continuous online monitoring of balance-of-plant assets with a digital connection to PLC or DCS systems for local analysis of multiple vibration bands. They are capable of installation in multi-drop configurations and reduce wiring requirements. HART functionality enables the user to specify vibration frequency bands, detector types and full-scale measurement ranges—effectively enabling field-configuration for specific monitoring requirements.
PCH420 sensors are powered by the network for continuous coverage, unlike wireless solutions only offering snapshots of asset performance and employing batteries that require frequent replacement. Utilizing PCH…

NAMUR blazes trail toward open control
NAMUR represents several thousand process control specialists, with about 300 participating in almost 40 working groups focusing on: measurement, controls, automation, communication, process management and electrical engineering, covering the entire plant lifecycle.
With the recent focus on the Open Process Automation (OPA) forum, ExxonMobil and Lockheed, it may seem there are no other open/interoperability efforts out there. This isn't true, as ably demonstrated by NAMUR, the “User Association of Automation Technology in Process Industries,” and its NAMUR Open Architecture (NOA) program.
Established in 1949, NAMUR is an international association of more than 140 user companies, and represents their interests in adding value through automation. In all, NAMUR represents several thousand process control specialists, with about 300 participating in almost 40 working groups focusing on: measurement, controls, automation, communication, process management and electrical engineering, covering the entire…

How automation can best affect the ratio that defines energy efficiency
Energy management and energy efficiency are key elements of the desired objective, and automation professionals can do their part by acting not only on the numerator (work required) but also on the denominator (energy supplied or inputs), says Ian Verhappen.
