CO2 Sensor for Railway Applications EE8915
v1.9 / Modification rights reserved | 2 EE8915 EE8915 measures reliably CO 2 concentration in harsh environment and complies with the relevant railway standards. Outstanding Accuracy and Long-Term Stability A multiple point CO 2 and temperature (T) adjustment procedure leads to excellent CO 2 measurement accuracy over the entire T working range -40…+60 °C (-40…+140 °F). The active compensation with on-board sensors leads to best CO 2 measurement accuracy independently of weather conditions, altitude or temperature. The E+E dual wavelength non-dispersive infrared (NDIR) measurement principle compensates automatically for ageing effects and is highly insensitive to pollution. Versatile and Suitable for Demanding Applications EE8915 is available for wall and duct mounting. The innovative design enables the combination of short response time and high protection class. The CO2 measured data is available as voltage and current output signals. Due to the compliance with tough railway standards, the EE8915 stands for excellent performance even under challenging conditions in any process and climate control application. Configurable and Adjustable The free EE-PCS product configuration software and the USB connection enable particularly user-friendly configuration and adjustment.
