摘要： Apparatus or systems which employ luminescence-quenching to produce a signal indicative of oxygen concentration. Components of such systems include: (1) an airway adapter, sampling cell, or the like having a casing and a sensor which is excited into luminescence with the luminescence decaying in a manner reflecting the concentration of oxygen in gases flowing through the airway adapter or other flow device and is in intimate contact with a window in the casing; (2) a transducer which has a light source for exciting a luminescable composition in the sensor into luminescence, a light sensitive detector for converting energy emitted from the luminescing composition as that the composition is quenched into an electrical signal indicative of oxygen concentration in the gases being monitored, and a casing which locates the light source and detector in close physical proximity to the window but on the side thereof opposite the sensor; and (3) subsystems for maintaining the sensor temperature constant and the temperature of the window above condensation temperature and for processing the signal generated by the light sensitive detector. Airway adapters, sampling cells, and transducers for such systems are also disclosed.

摘要： A method of and device for calibrating infrared radiation transducers. A concentration factor representing the ratio of a data signal to a reference signal for a known concentration of a designated gas in a sample containing that gas is generated. The concentration factor is stored and used during subsequent calibration procedures. The calibration device has a zero cell and a span cell with windows for transmitting infrared radiation and radiation reflecting or absorbing material in the span cell. The span cell therefore provides a known and consistent level of radiation absorption.

摘要： A transducer for nondispersive infrared radiation (NDIR) gas analysis and a passive device for verifying the calibration of the transducer. The calibration verification device can be mounted on a cable by which the transducer is attached to an associated signal processing-control-display unit (SPCDU) or monitor. Calibration parameters for the transducer are stored in a plug at the monitor end of the cable. The transducer includes an integrated subassembly of an infrared radiation source unit, an infrared radiation detector unit, and a flex connector and may be employed with an airway adapter preferably maintained by a thick film heating element at an above-dewpoint temperature to ascertain the concentration of a specie potentially present in gases flowing through the adapter. The transducer may also be employed for other purposes.
