EM-FECS(A) – Evaluation Module for FECS-series Sensors
The EM-FECS(A) evaluation module is designed to perform the testing and evaluation of the three-electrode electrochemical gas sensors in the FECS-series. Since the output voltage (VOUT) corresponding to the sensitivity characteristics can be obtained, the characteristics of the FECS sensor can be easily evaluated.
The FECS-series sensor is placed into the sensor socket on the EM-FECS(A). If target gas is present, the output current generated from the FECS-series sensor (*1) is converted into output voltage. A linear relationship exists between output voltage and target gas concentration. By measuring in advance the output voltage in a known target gas concentration, that gas concentration can be calculated from the measured output voltage values.
