Abstract: An automated testing apparatus for remotely performing a testing sequence to ensure that a sensor is functioning. The apparatus can include a detector, a storage container, a burst valve in fluid communication with the storage container, a testing control module in communication with the storage container and the burst valve, and a remote user interface remotely located from the detector. Preferably, the automated testing apparatus can simplify the testing procedure, increase the frequency of sensor testings, thereby notifying operations of sensor failures in a more timely fashion without the need for an operator to check the sensor locally.

Abstract: A method for monitoring the operation of a sensor is provided. The method comprises the step of representing the operation of the sensor by: i) storing a plurality of data values, each data value corresponding to the sensor output signal, wherein said step is performed during a time period such that said data values are distributed over a range of possible data values, ii) defining a plurality of discrete intervals within said range of possible data values; and iii) calculating the frequency of the data values within each interval thus forming a sensor representation. The method further comprises the steps of receiving at least one reference sensor representation; and comparing said sensor representation with said at least one reference sensor representation.

Abstract: The invention concerns a method for determining the concentrations of chemical components of a product, in particular air, in a distillation column, said method involving implementing a model for estimating the concentration of the components from measurements carried out by one or a plurality of sensors (41-45, 51-55), said model using an adjustment parameter making it possible to take into consideration operating variations of the column, the method comprising a step which involves detecting the values (200) of said adjustment parameter that are outside a nominal variation range of said parameter in order to diagnose a fault D in one or a plurality of said sensors.

Abstract: A method of testing a system (100) having at least one electrochemical gas sensor (100), such as an amperometric gas sensor, for detecting an analyte gas within a housing (102) of the system (100), the housing (102) having an inlet (104), the at least one electrochemical gas sensor (110) including an electrically active working electrode (150a) in fluid connection with the inlet (104) of the system (100), the method including biasing the electrically active working electrode (150a) at a first potential, to detect the analyte gas and biasing the electrically active working electrode (150a) at a second potential, different from the first potential, such that the at least one electrochemical gas sensor (110) is sensitive to a driving force created in the vicinity of the inlet (104) to test at least one transport path of the system (100). The method may further include creating the driving force in the vicinity of the inlet (104) of the housing (102) of the system (100) and measuring a response of the electrically active working electrode (150a) to the driving force. Said system (100) is therefore suitable for checking the performance of the electrochemical gas sensor (1), particularly to check that gas transport inside the system (100) is not prevented by diffusion blockage. The electrochemical gas sensor (110) is interrogated at bias voltages sensitive to different gas analytes, one being a target gas (e.g H2S) while the other being provided by, for instance, exhaled breath (e.g. C02).
