PRODUCT INFORMATION
EM-FECS(A) - Evaluation Module for FECS-series Sensors
Description:
Features:
The EM-FECS(A) evaluation module is designed to * Converts sensor output current to voltage output
perform the testing and evaluation of the three-electrode * Compatible with all FECS-series sensors
electrochemical gas sensors in the FECS-series. Since * Anti-polarization circuit during power OFF period
theoutputvoltage(VOUT)correspondingtothesensitivity
characteristicscanbeobtained, thecharacteristicsofthe
FECS sensor can be easily evaluated.
Operation:
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
(*1)
the FECS-series sensor
is converted into output voltage. A linear

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. (*2)

sensor output current into voltage output without
temperature compensation.
