PT0E-0730 １１．Detection principle １１−１．NDIR method (Non-Dispersive Infrared) The model is based on NDIR method (Non-Dispersive Infrared) and this structure is shown below. The infrared beam emitted from the light source passes through the measuring cell, and optical band pass filter which can pass the absorption wave of measuring gas and attains to the infrared sensor. The amount of infrared attaining to the infrared sensor through the measuring cell and will decrease according to its density.
PT0E-0730 １１−３．ELECTRO-CHEMICAL CELL method This gas detector applies an electrochemical sensor. The sample gas is electrolyzed by the electrolyzed cell added with specific electric potential (bias voltage) and detected from the electrolyzed current generated at that time. The electrochemical sensor is designed to keep the interface between electrode and electrolyte at a constant potential (Bias voltage) and is the method to electrolyze gas directly.
