Problems solved by technology

Unfortunately, this arrangement introduces a large thermal gradient and associated large thermal delay time between the thermistor sensor and the film temperature of the PbSe flat panel detector because the substrate on which the film is deposited is Made of fused silica, which is a poor conductor of heat

Embodiment Construction

[0080] Embodiments of the device of the invention described below generally include the following main elements:

[0081] The combined function of a temperature sensor (e.g., a chip thermistor) and an IR radiation detector (e.g., a lead selenide flat panel detector) for sensing the composition of the sampled gas in a temperature-compensated manner;

[0082] Small temperature sensors (eg, chip thermistors), which have low thermal mass. Chip thermistors are electrically and thermally connected to the flat panel detector electrodes to closely measure the detector film temperature;

[0083] a common electrical connection at a common ground between the temperature sensor terminals and the IR detector terminals; and

[0084] Complete three-wire connection assembly. One wire is connected for the PbSe flat panel detector bias and measurement output, the second wire is connected for the chip thermistor bias and measurement output, and the third wire is connected for the chip thermist...

Abstract

An improved infrared-based gas detector apparatus is described in which a substantial improvement in temperature measurement and tracking accuracy is achieved by combining a temperature sensing element such as a Thermistor to the body of a Lead Selenide (PbSe) plate detector. This allows for as close to possible measurement of the actual Lead Selenide film temperature without coming directly in physical contact with the film surface itself.

Description

technical field [0001] The present invention relates to an improved gas detection apparatus and method for significantly improving temperature measurement and increasing tracking accuracy by placing a temperature sensing element (e.g., a thermistor) in close proximity to an infrared (IR) sensitive detector ( For example, lead selenide (PbSe) thin film flat panel detectors) are combined to achieve the main body. The purpose of this modification is to allow the actual film temperature to be measured as close as possible without direct physical contact with the film surface itself. An example of such a device is a carbon dioxide gas detector in a capnography system. Background technique [0002] Many capnography systems use two IR detectors (eg, lead selenide detectors). One detector detects the sample gas absorption wavelength, while the other detector detects the reference wavelength. Both detectors must be closely monitored to determine any small changes in temperature be...
