GE Panametrics APX Oxygen Analyzer

GE Panametrics APX Oxygen Analyzer

Welcome to a Biomedical Battery specialist of the Panametrics Battery

The advanced paramagnetic GE Panametrics APX oxygen analyzer is the newest addition to the Panametrics line of thermoparamagnetic oxygen analyzers and transmitters.

The GE Panametrics APX oxygen analyzer is specially designed with advanced background gas compensation that makes it ideal for applications with defined or undefined hydrocarbon gases, including vapor recovery, flare gas, and refinery gas.

Advanced Background Compensation

The GE Panametrics APX oxygen analyzer's advanced background gas compensation not only measures the thermal conductivity of a gas but also measures the hat capacity and viscosity. By measuring these additional physical properties, the GE Panametrics APX oxygen analyzer with battery like Panametrics Magna-Mike 8500 Battery, Panametrics KR1800SCE Battery, NetTEST Battery, Tektronix REI DPA-7000 Battery, Tektronix TPS2000B Battery, Tektronix TPS2012B Battery, Tektronix TPS2014B Battery, Tektronix TPS2024B Battery, TSI TSI8532 Battery, TSI EP-03750 Battery, YUT Battery, YUT DR-202S Battery is better equipped to differentiate background gases that have significantly different or varying diamagnetic effects. This gives the GE Panametrics APX oxygen analyzer an advantage over other traditional dumbbell paramagnetic oxygen analyzers, which do not automatically compensate for the inherent diamagnetic effects of changing background gases. The result is that the GE Panametrics APX oxygen analyzer reliably measures oxygen more accurately in a broader range of applications with either known or unknown background gases.

Top Performance and Ease of Use

An onboard microprocessor gives the GE Panametrics APX oxygen analyzer the computing power to provide automatic oxygen signal compensation and integrated signal-processing algorithms. This enhances linearity and improves accuracy for reliable, long-term measurement.

The GE Panametrics APX oxygen analyzer also has sophisticated error-checking software with user-programmable defaults and error limits to detect abnormal measurement conditions, including a loss of flow to the analyzer or a pressure spike. The GE Panametrics APX oxygen analyzer is easily programmed through the multilevel, menu-driven interface, which provides convenient access for changing defaults, analog output scaling, and calibration.

Rugged Design and Low Maintenance

The GE Panametrics APX oxygen analyzer's sensor and electronic components are housed in a weatherproof and explosion-proof package that can be installed right at the measurement point to simplify wiring and provide trouble-free operation. The GE Panametrics APX oxygen analyzer's unique dual-chamber, temperature-controlled, oxygen-sensor design provides resistance to contamination, while minimizing temperature and flow sensitivity.

How it Works

Oxygen's paramagnetic property causes a gas sample containing oxygen to move within a magnetic field. Thermistor pairs, which are part of a wheatstone bridge circuit, sense the "magnetic wind" created by the gas movement. The resulting signal, along with heat capacity and viscosity measurements, are used by the microprocessor to calculate the oxygen percentage accurately.

Choice of Ranges

The GE Panametrics APX oxygen analyzer provides a 4- to 20-mA output signal that is fully programmable for zero and span. The output is proportional to oxygen concentration and is internally compensated for background gas and pressure variations. The GE Panametrics APX oxygen analyzer is available in a wide variety of measurement ranges.
