3000MA Paramagnetic Oxygen Analyzers - 1

TELEDYNE ANALYTICAL INSTRUMENTS for years with little or no attention making them ideal for critical measurements in the low percent range. FLEXIBILITY The 3000MA offers three dynamic, user configurable ranges plus autoranging, and can be calibrated in any range. The instrument is linear on all three ranges, eliminating the need to recalibrate while switching between ranges. The analyzer comes standard with an isolated 4-20 mADC output for oxygen concentration and range identification. Additionally, a bidirectional RS-232C serial communication interface provides for remote monitoring and control of span and zero functions. Teledyne provides auto-calibration capabilities as a standard feature in the 3000 series platform. APPLICATIONS • Monitoring inert gas blanketing Paramagnetic Oxygen Analyzer • Microprocessor based • Exceptional performance, price value • Advanced paramagnetic sensor • Designed for air separation industry Teledyne’s Model 3000MA Paramagnetic Percent Oxygen Analyzer is a versatile, microprocessor based instrument specifically designed to detect oxygen in a variety of gases. The 3000MA is a precise, cost effective instrument capable of measuring percent oxygen in as low as the 0-1% range. Drawing on the solid performance of Teledyne’s highly successful 3000 series control platform, the 3000MA provides the user with a wide variety of features and options to satisfy virtually any application. PRINCIPLE OF MEASUREMENT The physical property distinguishing oxygen from other gases is its paramagnetism which is significantly greater than that of common gases. Consequently the molecules of oxygen are attracted by strong magnetic fields which can be used in detection. A paramagnetic sensor consists of two spheres arranged in the form of a dumbbell suspended in a symmetrical, non-uniform magnetic field. When the surrounding gas contains oxygen, the dumbbell spheres rotate out of the magnetic field by the relatively strong attraction of oxygen. • Air separation and liquefaction • Chemical reaction monitoring • Emissions monitoring • Petrochemical process control • Quality assurance • Gas analysis certification THE LEADER IN OXYGEN The 3000MA can be ordered as a standard unit or as part of a larger analytical system. With over 50 years of analytical instrument experience, Teledyne supplies sensors, custom engineered analyzers and complete monitoring systems to satisfy unique applications. From portables to on-line units, in microprocessor based or analog configurations, no other manufacturer comes close to matching Teledyne’s breadth of instrumentation. ADVANTAGES • Linearity of analysis across three user-selectable ranges • Autoranging to follow process upsets • Auto-calibration electronics standard A light beam focused on a mirror attached to the dumbbell reflects asymmetrically onto two photo diodes resulting in a voltage shift. The voltage difference produces a current used to drive the dumbbells back to the original position. The current flow required to maintain the null position is directly proportional to the oxygen concentration and is shown linearly in volume percent oxygen in the display. Properly maintained paramagnetic sensors last Built for Reliability and Performance
