Title: Abnormality-detection method of oxygen analysis device
Inventor: SASAKI YUICHI
IPC: G01N27/41
Filed: 1991-07-15
Abstract: PURPOSE:To achieve a highly reliable gas calibration by judging an abnormality due to damage of a filter, an abnormality of a supply pipe, etc., by determining whether a sensor signal is within a specified region or not. CONSTITUTION:A calibration gas is introduced into a sensor portion of an oxygen analysis device and a sensor output is stored as E0 after a sensor setting time T0 passes. After the time T0 passes, a sensor signal Em is measured continuously for any time interval tw and it is judged whether the sensor signal exists between an upper-limit value SU and a lower-limit value SL or not. When the output Em does not exist between the values SU and SL, it is judged that the sensor is abnormal and a sensor abnormality signal is output. When the output Em is between the values SU and SL, Ec=¦Em-E0¦ is calculated continuously and Ec is compared with a preset reference value  E continuously. Then, when Ec is smaller than the value  E, it is judged that the sensor is normal. On the other hand, when Ec exceeds the value  E, a calibration gas abnormality signal is output.
