T X 6 3 5 1 . 0 2 e T X 6 3 5 2 . 0 2 e SENTRO GAS SENSOR/TRANSMITTER sentro modules... There is a wide choice of sensing modules and each one stores all the necessary data about its type identification, sensing range and specific calibration. This data is automatically recognised by SENTRO when the eModule is plugged in. 4000 points of date-stamped measurements are also logged and can be reviewed by connecting the module to a USB port of a standard PC. The service history of the module and the condition of the sensing element are also recorded. The eModules are pre-calibrated so can be substituted at any time by a replacement module – usually of the same type, but an alternative may be inserted if required. Security coding can be used to ensure that the same type of SENTRO eModule is always used. ...'smart' gas modules SENTRO eModule TOXIC GASES • ELECTROCHEMICAL CELLS SENTRO eModule for monitoring toxic gases present in the environment using electrochemical cells, combining good sensitivity at low gas concentrations with high range capability and excellent stability. The cells have a natural life of about two years, dependent upon monitoring conditions and the module can be quickly replaced and serviced at the end of its working life. Toxic gas SENTRO eModules have very low power consumption so enabling the 4...20mA two wire, line powered version of SENTRO (TX6352) to be used when preferred.
