Safety


safe lasers are used to penetrate thick fog, heavy rain and snow beyond the capability of traditional open path infrared (OPIR) detectors. With the automated SimuGas™ safety integrity self- check, there is no need for the typical OPIR sensor gas checks and recalibrations requiring field technician time to address. Unlike electrochemical cells, Senscient ELDS sensors are also immune to sensor poisoning and interferent gases, thanks to their gas specific harmonic fingerprint detection.


Innovation 2: Touch Screen Displays


The point of fixed gas detectors is that they can be located where people might rarely come into contact with a combustible or toxic gas until it is too late. On the other hand, there are many locations where the transmitter can be placed where it is more convenient and less labor intensive for factory technicians to review and confirm alarms, diagnostics data or make updates.

With an industry-first touch screen button interface and a bright OLED display, the ULTIMA X5000 Gas Monitor makes it easier than ever to view plant safety data. The field of view of this new generation of OLED displays improves visual ergonomics for technicians who are often working under challenging plant conditions. The X5000’s colorful text and icons show a gas reading gauge, progress bar, operational status, maintenance alerts and alarms.


Innovation 3: Wireless Bluetooth


Employee falls are one of the most common causes of accidents in process and manufacturing plants. Fixed gas detection monitoring systems often must be located and directed in high or other hard to access locations near piping or valves and other critical equipment that must be monitored continuously for combustible or toxic gas leaks.


With the improved security of wireless technology, the addition of optional Bluetooth®


communications to the ULTIMA X5000


gives plant technicians with mobile devices an HMI screen and fully capable controller at their fingertips. All functions can be reviewed and performed up to 75 feet (23 meters) away for added safety and convenience in difficult to reach locations.


Innovation 4: Digital Bus Communications

The evolution of standardised digital communications, such as the HART protocol, offers many advantages to plant and corporate teams in terms of bringing the right data to the right systems both at individual plants and to large corporate networks. HART protocol, for example, provides process information to DCS, PLC and other plant control systems that can issue safety alerts in the event of a combustible or toxic gas leak and initiate gradual plant shut-downs based on those alerts, compile historical event data and more.

The ULTIMA X5000 Gas Monitor is available with HART 7 protocol. That means carbon monoxide and hydrogen sulfide XCell® with TruCal®


Sensors technology from MSA are capable of sending sensor


status via HART into a plant’s preventative maintenance system, further automating the sensor maintenance process.


Innovation 5: Onboard Diagnostics


Depending on the sensor technology chosen, nearly all gas detection monitoring systems require periodic maintenance. The routine maintenance required can range from periodic cleaning, sensor calibration, sensor replacement or monitoring for signs of sensor poisoning that degrades performance and reliability.


To improve the ease of use of toxic gas detectors, MSA’s advanced XCell®


Sensors are designed with TruCal technology that actively monitors sensor life, compensates for environmental factors such as high temperatures or humidity and adjusts for drift. For worry- free operation, XCell sensors with TruCal self-check four times per day with an electrical pulse, which mimics the real application of gas eliminating the need for manual intervention. They are designed with a typical five- to ten-year sensor life, depending on the gas and sensor type.


Conclusions


Safety will always be Job #1 in hazardous industries such as oil/ gas, chemical processing and many others where combustible and toxic gases are potentially present. The safety industry has a long history of innovation and recognises the need to improve performance, increase reliability and simplify use and maintenance. If you’re planning to upgrade, retrofit or expand your facility, make fixed gas detection one of the first priorities.


Talking early with safety professionals will ensure that you’re able to optimise the gas monitoring safety of your plant. Don’t wait until late in the process or you could find yourself with unnecessary safety challenges—think ahead. If you have a problem, be sure to reach out quickly to safety industry professionals who see the same or similar problems every day and can assist you in resolving them with fewer headaches at the lowest possible cost.


Flame Detection With a Big Difference!


Analytical Technology is proud to announce a new product to their Gold Standard of gas detection.


ATi’s new combination of Flame and Gas Detection Systems allows a one-stop solution to customer requirements, including a full installation and commissioning package.


The ATi301-V is a self-contained CCTV Flame Detector, with false alarm immunity and incident recording for post analysis.


If a fire can be seen by the naked eye, then this detector will work. As it doesn’t rely on traditional heat detection like Infra- Red or Ultra Violet, it will trigger through glass and windscreens - welding, grinding and sunlight will not cause false alarms. With traditional infra-red detectors, rain and mist can reduce detection performance, meaning alarms may not trigger.


However, this does not happen with the ATI301-V as it works within the visual light spectrum. The ATi301-V also sends live video streaming for remote viewing - a bonus for seeing what’s going on prior to entry. In addition, ATi has developed wire-free video transmission, which can be viewed on a smartphone.


Developed for the harsh Oil & Gas Industry as an ATEX Zone 1 approved and SIL rated performance device, both explosive and safe area situations are covered. If coupled with ATi’s unique self-checking AutoTest Gas Detection devices, there is no application that cannot be covered.
