Gas Filter Correlation CO Analyzer
Model N300
-
Teledyne Advanced Pollution Instrumentation
The Model N300 is a microprocessor-controlled analyzer based on the Beer-Lambert law that is used to determine the concentration of carbon monoxide (CO) in a sample gas.The N300 uses Gas Filter Correlation (GFC) to overcome the interfering effects of various other gases (such as water vapor) that also absorb Infrared (IR) light. The analyzer passes the IR light beam through a spinning wheel made up of two separate chambers: one containing a high concentration of CO known as the reference, and the other containing a neutral gas known as the measure. The concentration of CO in the sample chamber is computed by taking the ratio of the instantaneous measure and reference values and then compensating the ratio for sample temperature and pressure.

Servo And VFD Filters
-
Operation of PWM-driven motors – servo motors and variable frequency drives (VFD) – causes several problems in equipment, including damage to the motor’s bearings due to leakage current causing electrical discharge machining (EDM) and damage to motor’s insulation. PWM motors also are a major source of EMI in equipment. These motor drive systems use pulsed power to drive the motors. As we are aware, the sharp edges of the pulses inevitably include high frequency components which can couple or radiate as noise to other parts of your system and cause unreliability, communication/control problems and EMC compliance issues.
