Online resources: Optimize calibration
Taking on calibration online resources. Here's what can help you optimize your calibration processes
DIGITAL DEVICES NEED CALIBRATION
Many people are under the mistaken impression that they don't have to calibrate their digital transmitter, in part because they don't have the facilities to do so with the accuracy possible at the factory. However, not doing at least a reference check on a regular basis, including at commissioning, is a bad idea. Ian Verhappen explains why, with today's smart instruments, doing such a check is easier than it ever was before.Control Global

'Working Monitor' Regulator Solves Pressure Problems
Michael Calaway and Ryan Baker discuss two redundant regulator configuration options and an application example at Dow Freeport
Fuel gas provides the heat essential to many process manufacturing operations. Accurately controlling its pressure is important for optimum combustion and energy efficiency, and regulator reliability is critical to ensuring continuous operations.
During a presentation entitled "Gas Pressure Control: Why a Working Monitor Regulator System?" at the Emerson Global User Exchange this week, Michael Calaway, business development manager at Emerson Process Management, together with Ryan Baker, Fisher Valve and Regulator account manager from local business partner Puffer-Sweiven, discussed two redundant regulator configuration options as well as an application example at Dow Freeport.

Meggitt provides HART-enabled piezo-electric vibration sensors
Meggitt's PCH420 series are the first HART-enabled piezo-electric vibration sensors 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.
Meggitt's PCH420 series are the first HART-enabled piezo-electric vibration sensors 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 support 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 which only offer snapshots of asset performance and utilize batteries that require frequent replacement. PCH systems are…

BLH Nobel Introduced a System That Quickly and Easily Checks Weighing Systems for Wiring and Mechanical Faults
Load cell weighing systems solve some of the knottiest problems in batch and level control by directly measuring masses of solids and liquids as they're accumulated, dispensed or conveyed. But the load cells must be installed and wired properly, and the load structure must be engineered and constructed correctly to distribute the measured load as axial forces on the cells. What appear on the surface to be simple wiring and construction tasks have caused more than a few problems during commissioning and maintenance due to miswired or poorly made connections, distorted or binding structures, incorrectly installed load cells or rigid connections to adjacent equipment.
Such problems often are not found until a new installation is being…

Why not more sophisticated capabilities for motors and drives
Developers and users are looking past their motor and drives' hard exteriors to find new, flexible and unexpectedly sophisticated capabilities
Sometimes the familiar mass and density of hardware can be a bit of an illusion. The apparently hard reality of all those motors and drives in all their thousands of pumps, mills, fans, conveyors, drills and other equipment can convince engineers and other users that they're just unchangeable objects.
However, their common mission is turning energy and electricity into mechanical power, and remembering this essential truth can free developers and users from their routine perspective to see the potential for motors and their supporting drives, controls and software to make new gains and be applied new ways. Of course, variable-speed/frequency drives have been the biggest advance in recent years, but they aren't alone.

Greenfield mining operation protects assets with WirelessHART
Lundin Mining chose to install a WirelessHART network to monitor and protect its essential equipment
It isn't easy to run a high-grade nickel and copper mining and milling operation in the harsh environment of Michigan's upper peninsula. Sub-zero temperatures, demanding terrain and long distances between facilities make it difficult to maintain plant assets in optimal working order.
Sites like Lundin Mining Corporation's Eagle Mine in Michigamme Township, Marquette County, Michigan, need an easy and cost-effective way to measure process variables. Mining operations are up to ¾ mile from the main facility at the Eagle site, and many locations are not staffed on a 24/7 basis—creating the need for a remote monitoring capability.

Genpak plant roof collapses as staff evacuate building
Part of building expected to fall completely as firefighters scramble for a plan.
Panic struck Peterborough, Ontario, Canada last month when the Genpak plant's roof collapse and emergency services staff were forced to evacuate.
The gas feed to the building was shut off and firefighters evacuated everyone from the building, but shingles continued to fall and the roof continued to dip slowly. Firefighters were scrambling to develop a plan in case the roof collapsed completely.
Witnesses say new shingles were loaded on the roof yesterday, in preparation for repairs.The City's chief building official went into the plant shortly after 10 a.m. to take a look at the structure.
Located at 25 Aylmer St. North, Genpak has 61 employees. It specializes in process packaging for a wide range of products.

Electromagnetically transparent GRP enclosures see spike in demand
Equipment housings to contain wireless process monitoring equipment in outdoor environments are on the rise - here's why.
Intertec is seeing increased customer demand for equipment housings to contain wireless process monitoring equipment in outdoor environments. The company attributes this partly to increased use of industrial wireless sensor network (WSN) technology, but mainly to the growing industry awareness that the glass-reinforced polymer (GRP) composite material it uses for all of its protective enclosures is electromagnetically transparent.
Until recently, process industry take-up of WSN technology has been relatively slow, possibly because competing wireless standards have made systems designers wary of making the wrong choice. However, for mainstream industrial process applications, the field has now narrowed to just two standards –…
