Cables - Best Practices for Process Instrumentation Cabling - Connectivity glues the network together; Cabling, grounding, cable routing, and the mitigation of noise and interference - Saeed M. AL-Abeediah - The health and effectiveness of any plantís Process Automation System (PAS) relies on many factors. Among these factors is the proper selection of PAS components, seamless integration, control schemes, control system installation, and last but not least, proper electrical installation and connectivity of field instrumentation devices. This last factor, which glues the entire PAS system together, involves cabling, grounding, cable routing, and mitigation of external influences such as noise and interference. Thanks to the ISA and InTech.
Cable Glands Why
Should You Specify Cable Glands? - How often have we heard:- "We
don't specify Cable Glands, as long as they have the relevant certification then
it must be fit for purpose. We leave it to contractor to sort out. We are too
busy concentrating on the high value, long lead time items to bother about such
an insignificant value product. In a recent paper presented at the Hazard Ex
conference by a Senior Manager of CENELEC Standards Inspections, it was stated,
"Resources should be directed at eliminating the following common faults;

CANopen was designed for motion-oriented machine control networks, such as handling systems. By now it is used in many various fields, such as medical equipment, off-road vehicles, maritime electronics, public transportation, building automation, etc.
HART - The HART Protocol was developed in the mid-1980s by Rosemount Inc. for use with a range of smart measuring instruments. Originally proprietary, the protocol was soon published for free use by anyone, and in 1990 the HART User Group was formed. In 1993, the registered trademark and all rights in the protocol were transferred to the HART Communication Foundation (HCF). The protocol remains open and free for all to use without royalties. This technical section focuses on providing information that is relevant to the various aspects of the HART Protocol. We will discuss what it is, how it works, and the benefits of using the HART Protocol.

Pilot System Safety - John Bellovich, Jim Franklin, and
Bob Schwartz - One of the
worst nightmares a plant manager can experience is
a complete flare system outage. The flare system is
the last line of defense for many refining and petrochemical
facilities and, when out of commission, can cause
the shutdown of the entire facility. Flare ignition
failure may lead to unburned venting of dangerous gases,
and may develop into an explosive hazard leading to
the loss of property and equipment, or worse,
injury to personnel or loss of life. The safety and effectiveness
of flaring are dependent upon one or more continuously
burning pilots for immediate and sustained ignition
of gases exiting a flare burner. Because pilot
failure can compromise safety and effectiveness, it should
be detected quickly and accurately to allow prompt
automatic and/or operator response. Proper disposal
of process and waste gases during routine and/or
emergency conditions is crucial to help operating facilities
protect plant employees and the surrounding community,
and to avoid hundreds of thousands of dollars in
fines. These reasons alone make the pilot monitoring
and ignition system the most important component of
any flare system. The advanced flare pilot systems
explained in this article offer increased protection
from harsh environmental conditions and rapid
notice of pilot flame failure. Recently published industry
standards for flare pilot design and performance are
also discussed - from John Zinc Company.
2.13 Install Electronic Flare Ignition Devices - This technology replaces the intermittently or continuously burning flare pilots with electrical sparking pilots similar to a modern gas stove. These sparking pilots require low electrical power that can be supplied from a battery with solar recharge in remote sites. In addition to using electronic flare ignition devices for pilots, facilities may also install sensors to detect the pilot sensors to detect the pilot flame and shut off fuel gas if the pilot is extinguished - from EPA.
2.13 Developments in the Field of Electronic Ignition Flaring Systems - With the developments in chemistry and petrochemistry on one hand, and concern for the environment on the other, more and more requirements are being set for the emission of flaring systems. Flaring systems have undergone considerable development, from a pipe with a perpetual flame to a well thought-out combustion system with pilot flame burners, purge gas, steam injection and automatic ignition - from Smitsvonk Holland BV.

Reading HART Data into Non-HART Systems - Many HART products are able to perform more than one measurement or output function (e.g., make multiple process measurements, calculate process information, and provide positioner feedback information). All of this information can be easily accessed digitally. However, existing controllers or interface equipment may not have the ability to read digital HART data. Products are available that can read HART digital signals and convert them to analog (4-20mA) and alarm trip (contact closure) information, which enables any traditional analog control system to take full advantage of the benefits of HART- communicating devices.

Instrument Air Receivers - Warning on Air Receivers - WorkSafe Victoria has released new guidance focussing on the safety risks associated with air receivers - a type of pressure vessel used to store compressed air for large demands greater than a compressor's capacity. WorkSafe director Ross Pilkington says air receivers have the potential to seriously hurt people and damage property if they were not properly installed or maintained. There have been serious incidents involving air receivers exploding in Victorian workplaces - and it has only been good luck that no one was working near them at the time. Employers with air receivers must ensure they are properly maintained to reduce the risk of explosion or fire. The handbook 'Working safely with air receivers' is aimed at improving awareness of the risks associated with air receivers, and explaining ways to eliminate and reduce those risks.

3.13 Introduction to Valves - By definition, valves are mechanical devices specifically designed to direct, start, stop, mix, or regulate the flow, pressure, or temperature of a process fluid. Valves can be designed to handle either liquid or gas applications. By nature of their design, function, and application, valves come in a wide variety of styles, sizes, and pressure classes. The smallest industrial valves can weigh as little as 1 lb (0.45 kg) and fit comfortably in the human hand, while the largest can weigh up to 10 tons (9070 kg) and extend in height to over 24 ft (6.1 m). Industrial process valves can be used in pipeline sizes from 0.5 in [nominal diameter (DN) 15] to beyond 48 in (DN 1200), although over 90 percent of the valves used in process systems are installed in piping that is 4 in (DN 100) and smaller in size. Valves can be used in pressures from vacuum to over 13,000 psi (897 bar). An example of how process valves can vary in size is shown in Fig. 1.1. Todayís spectrum of available valves extends from simple water faucets to control valves equipped with microprocessors, which provide single-loop control of the process. The most common types in use today are gate, plug, ball, butterfly, check, pressure-relief, and globe valves. Valves can be manufactured from a number of materials, with most valves made from steel, iron, plastic, brass, bronze, or a number of special alloys - from mhprofessional.com.
