Surge Protection for the Fieldbus System Definition The effects of a lightning strike, even at a distance of 500 m, endangers electronic/electric equipment. The main purpose of the surge protection barrier is to limit induced transient voltage over sensitive electrical equipment and to divert the surge current safely to a controlled point to earth. Surge Protection for the Fieldbus System A surge that effects the fieldbus cables (e.g., trunk cable) travels either toward the control system or toward the field devices through the field junction box. Or a surge can effect the spur cables and travel either toward the field devices or toward the control system through

Standard Gas Detection Definitions Volume CH4: The percentage by volume of combustible methane gas in an area. At 5% volume the mixture of methane is at 100% LEL and will explode if combined with oxygen and a spark. % Volume: Volume of a gas in air (i.e., 20.9% volume of oxygen is the standard percentage of oxygen by volume in air). Absorption: The gas penetrates the solid surface by chemical reaction. Adsorption: The collection of gas or liquid molecules on the outside or surface of another material. Bump Gas: This is a term used in the industry as of just recently to check if

Infrared Open Path Gas Detectors Working Principle An alternative method of measuring gas concentration is based on absorption of infrared (IR) radiation at certain wavelengths as it passes through a volume of gas. Devices using this technology have a light source and a light detector and measure the light intensity at two specific wavelengths, one at an absorption (active) wavelength and one outside of the absorption (reference) wavelength. If a volume of gas passes between the source and detector, the amount of light in the active wavelength falling on the detector is reduced, while the amount of light in the reference wavelength remains unchanged. Much like the catalytic detectors, the gas concentration is determined from the relative

Why Negative Readings in Gas Detectors ? Why Negative Readings in Gas Detectors ? This is a common question that is frequently asked.  As recently as today in fact. So, why do you sometimes see negative readings on your gas detectors/monitor? All electrochemical or catalytic gas sensors can be prone to both positive and negative drift due to environmental factors such as changes in temperature and humidity.   However these are not the most common causes of negative sensor readings. Negative sensor readings more commonly occur when your instrument has been “zeroed” in a contaminated atmosphere, where small levels of the sensors’ target gasses are present.   When

Field Transmitter Communication Troubleshooting When intelligent devices are not communicating or show abnormal status for any reason the DD file often get blamed first. However, the DD file is usually not the problem so time is lost. Indeed an EDDL file cannot fail. If the problem is a missing DD file, the system will display an error message saying the DD file is missing. If there is no such error message, the problem is something else. This guide provides hints for troubleshooting HART, FOUNDATION fieldbus, PROFIBUS, and other digital communication. Troubleshoot from the ground up, starting with power supply, then communication, and lastly system

Fieldbus Analog Input Function Block The Analog Input (AI) function block processes field device measurements and makes them available to other function blocks. The output value from the AI block is in engineering units and contains a status indicating the quality of the measurement. The measuring device may have several measurements or derived values available in different channels. Use the channel number to define the variable that the AI block processes. The AI block supports alarming, signal scaling, signal filtering, signal status calculation, mode control, and simulation. In Automatic mode, the block’s output parameter (OUT) reflects the process variable (PV) value and status. In Manual

Two Element Drum Level Control System A two-element drum level control system is capable of providing close adherence of drum level to its set-point under steady-state conditions as well as being capable of providing the required tight control during a transient. Its performance during transient conditions permits its use on many industrial boiler applications. Such applications are characterized by adequately-sized drums used with load changes of moderate rate and degree. These characteristics are usually found in plants with continuous-type processes, and those with mixed heating and processing demands. Caution should be exercised in its use on systems without reasonably constant feedwater pressure. The term 'two-element' is
