摘要： A method and apparatus for gas detection uses a sensor such as an electrochemical (EC) cell and includes a feedback control loop to control a pump to establish a first predetermined gas flow rate to the EC cell. The concentration of the gas at the first predetermined flow rate is measured. If the detected concentration exceeds a predetermined Alert value at the first flow rate an Initial Warning without remedial action is generated, and, the system then changes the gas flow rate before an Alarm is indicated. An Alarm is signaled only if the system verifies the first measurement. Preferably the first flow rate is set to optimize the measurement accuracy of the EC cell being used, and the second flow rate is lower than the first. Verification of an Alarm at the first flow rate may be conducted quickly by a quick-reaction process. The controller may periodically cycle the flow rates between the first and second rates for better accuracy and faster verification times.

摘要： The present invention provides a colorimetric gas detector comprising a substrate bearing a material that can react with a gas in an atmosphere being monitored and wherein the reaction causes the material to change the radiation at which the material absorbs or radiates radiation (the color-change material). The material is located in at least one discrete area of the substrate. By providing the color change material in discrete areas, the amount of such material can be reduced and different types of color-change material can be included on a common substrate to detect two or more gases simultaneously.

摘要： There is disclosed a method of operating a calorimetric gas detector system that comprises a substrate (1) bearing a material (12) that can react with a target gas to produce a change in the wavelength of radiation absorbed or transmitted by the material (“colour-change material”). The method involves: a) applying onto a region (15) of the substrate that includes colour-change material a chemical of predetermined concentration that reacts directly or indirectly with the colour-change material to produce a change in the wavelength of the radiation absorbed or transmitted by the material; b) detecting the radiation absorbed or transmitted in said region (15) at a wavelength absorbed or transmitted by the reaction product of the colour change material with the chemical, and c) generating a signal in accordance with the amount of radiation detected at the second wavelength, said signal being dependent on the amount of colour-change material on the substrate. The signal can be used to correct the reading of the colour change material when exposed to target gas to compensate for varying amounts of colour-change material on the substrate.

摘要： A gas sensor including a housing containing at least a sensing electrode, a counter electrode, a test electrode, and electrolyte means in contact with such electrodes. The housing permits gas from the environment to flow to the sensing electrode. The gas sensor is operable either in a normal mode of operation in which potentials are applied to the electrodes for detecting when a gas to be sensed is present at the sensing electrode, or in a test mode of operation in which potentials are applied to the electrodes so that the test electrode generates a gas which flows to the sensing electrode to enable an indication whether the sensor is operating correctly.

摘要： A method of making an electrical connection of a conductor (1) to a thick film track (2) mounted on a substrate (3) includes the steps of heating the conductor (1) to a temperature at which it may melt the glass constituent of the track (2), and inserting it into the track (2) such that it sinks in and contacts the metallic constituent of the track. The glass sets, fixing the conductor in place. Thus the need for a second firing operation is avoided.
