The MSA Ultima X5000 Gas Monitor

MSA Ultima X5000 Gas Monitor
The MSA ULTIMA® X5000 features a new design equipped with an Organic LED (OLED) display and bright status LED’s for extreme visibility. The gas monitor employs Green, Yellow and Red LED’s to signal normal, fault and alarm conditions.

Dual sensing technology doubles the sensing power with half of the footprint of a single gas transmitter. Sensors can be remotely mounted, mixed and matched to suit your gas detection needs.

Bluetooth wireless technology allows you to use your mobile device as an HMI screen and controller. The X/S Connect App is designed with high security standards and provides real-time information to your mobile device. Reduces setup time by at least 50%.

MSA’s patented XCell® sensors with TruCal® technology, extends calibration cycles up to 18 months. TruCal technology actively monitors the sensor integrity and compensates for environmental factors that cause regular electrochemical sensors to drift, allowing calibration cycles to be extended well beyond industry standards. TruCal can greatly reduce downtime and provides peace of mind.

Pneumatic Vane Damper Drives for Boiler Flue Gas and Combustion Air: A Superior Alternative to Electric

Obsolete ID fan inlet damper drive.

Pneumatic damper drives are excellent alternatives to electric drives because of speed, accuracy, and reliability. Pneumatic vane damper drives don't have gears or motor windings that slow down response or introduce slop. Pneumatic vane drives react to signal changes and produce movement instantaneously and repeatably.

In flue gas and combustion air applications, rapid response is critical for optimal efficiency, safety, and equipment longevity. In power plants, Rotork Type K damper drives provide a better solution for critical damper applications over electric drives.

Balanced-draft power generation boilers can experience very serious equipment failures if low pressure conditions exist inside the combustion chamber. Transients in boiler pressure can cause combustion complications leading to irregular heating of steam tubes, and in extreme situations, negative boiler pressure can collapse boiler walls and buckstays. There is a possibility for catastrophic failures (ruined boiler tubes, destroyed  refractory, boiler structural damage) leading to long shutdowns, lost production, and expensive re-construction.

Understanding the catastrophic possibilites, it is extremely important to provide consistent internal operating pressure environment for efficient and manageable combustion. ID (induced draft) fans on combustion boilers play a critical role in maintaining reliable boiler pressure. In turn, the ID fan inlet damper control system that regulates fan induced airflow and pressure need to be accurate, responsive, and reliable to assist in keeping boiler combustion chamber pressure fluctuations in check.

Type K damper driveRotork Type K 'PM Series' Pedestal-Mount TK-6 Damper Drives have proven themselves time and time again to be the best choice for these applications. Pneumatic vane drives deliver high torque at tested speeds of less than 3 seconds for a full 90-degree stroke. They offer drop-in-place retrofit to the existing damper drive footprint, plus smart positioner technology. The Type K Drives perform quickly and smoothly at full boiler pressure and damper load, and as required, fail to the fully closed position.

For use on boiler dampers, the years of maintenance-free operation, in thousands of successful installations world-wide, the data clearly demonstrates pneumatic drive's superiority over electric drives.

Finally, always discuss your damper drive application with an experienced applications engineer for best selection, optimal performance, and maximum safety.
