Cirius1 Infrared Sensor for Hydrocarbons Description and Operation The Cirius range of sensors use the non-dispersive infrared method to detect the presence of gases. The sensors contain an infrared radiation source, a dual element infrared detector and a patented optical arrangement into which gas diffuses. The dual element infrared detector responds to changes in incident radiation and to operate he sensor the infrared source should be pulsed with a duty cycle of 50% at a frequency typically between 2Hz and 4Hz. The sensor produces outputs for active wavelengths, which are modified by the presence of target gas, and for reference wavelengths, which are not modified by the presence of target gas. These outputs consist of a small AC signal in sympathy with the source pulse that is superimposed on a DC voltage pedestal. The sensor also provides a measure of internal temperature via an embedded thermistor. The sensor requires a voltage supply to operate the infrared detector and the connections to the sensor follow the industry standard 7 pin format. To operate the sensor it must be connected to a suitable circuit that provides the source drive and extracts the small AC signals from the DC voltage pedestal. The circuit must amplify the small AC signals, extract a value from them and treat the results to provide a linear output related to gas concentration. The temperature output from the sensor should be used to apply temperature compensation in order to achieve the full performance specification. Cirius1 Infrared Sensor for Hydrocarbons Features * Sensing ranges: 0-100% LFL Methane, 0-100% LFL Hydrocarbons and 0-100% volume Methane * All metal construction * Small internal volume * 'Lightlocked': not affected by external illumination * Low power * Active and Reference signal outputs * Embedded thermistor temperature sensor output * Wide operating temperature range * Fast response * Immunity from 'poisoning' * Fail safe operation * Zero maintenance * Electrically isolated housing
NAP-57A Catalytic Type Gas Sensor Description NAP-57A is a newly developed catalytic type gas sensor based on conventional type NAP-56A for not only residential but also commercial or semi-industrial applications because of having highly excellent poisoning resistivity. Since its power consumption and pin positions are completely the same as NAP-55A and 56A, it is easily replaceable as it is. However, it does not possess the explosion proof by itself, then it is recommended to install it into an explosion proof chamber for actual application. NAP-57A Catalytic Type Gas Sensor Features * Good stability * Excellent repeatability and detection accuracy * Good linearity against gas concentration at wide range * Quite excellent poisoning resistivity * Down sizing for design flexibility of gas alarm or detector NAP-57A Catalytic Type Gas Sensor Usage * Gas alarm or detector of general combustible gases for all applications * Gas densitometer * Driving module for gas leakage detector

However, it is important that exposure to high concentrations of solvent vapours is avoided, both during storage, fitting into instruments, and operation. When using sensors with printed circuit boards (PCBs), degreasing agents should be used before the sensor is fitted. Do not glue directly on or near the CiTiceL as the solvent may cause crazing of the plastic.
