Flue gas analyzer gets close to the source
Sensor design allows placement in high-temperature zone for accurate readings while maintaining long operational life with minimal maintenance.
Michell Instrument's XZR-500 flue gas analyzer reduces installation and operating costs with its innovative Metallic Sealed Reference Sensor (MSRS). Operating reliably at temperatures up to 1,500 °C (2,730 °F), the company says its analyzer's semi-in-situ design makes it easy to install, simple to operate and economical to maintain.
Designed for applications such as boiler combustion efficiency and industrial waste incinerators, the XZR-500 provides simplicity of installation and fast response of an in-situ analyzer, combined with the long sensor life of an ex-situ analyzer.
With its MSRS sensor, the XZR-500's temperature range allows it to be installed close to the radiation zone. Taking the measurement in this high-temperature location gives reliably accurate readings before there's a chance that ambient air leakage farther downstream can contaminate the sample gas resulting in false readings.
MSRS technology is based on a sealed metallic reference allowing air to be used as a calibration gas which reduces installation and maintenance costs. If sensor replacement is needed, it can be performed within minutes without interrupting the process.
Michell claims a longer sensor lifespan than zirconia-based analyzers, even in dirty applications. Where soot is a problem, such as coal-fired power stations, the MSRS cell can be combined with a particle blow-back mechanism to maximize reliability.

Annual Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
