E+E Elektronik announces EE820 sensor

April 18, 2019 - The EE820 sensor from E+E Elektronik is appropriate for monitoring the CO2 concentration in harsh and polluted applications such as agriculture and life stock barns. Beside voltage and current output, the sensor is now also available with RS485 interface with Modbus RTU or BACnet MS/TP protocol.

The operation of the EE820 is based on the E+E dual-wavelength NDIR principle, which is insensitive to contamination and automatically compensates for aging effects. The multi-point CO2 and temperature factory adjustment procedure ensures CO2 measurement accuracy over the entire temperature range -20…60 °C (-4…140 °F).

The EE820 features an IP54 enclosure with a special filter, which offers protection of the measurement electronics in harsh and polluted environment. The functional enclosure facilitates mounting the sensor with closed cover. Thus, the electronics is safe from mechanical damage and construction site pollution during installation.

For response time to changes in CO2, the EE820 is optionally available with a forced air circulation module installed behind the filter.

The measured data with range up to 10000 ppm CO2 is available on the analogue output (voltage / current) or on the RS485 interface with Modbus RTU or BACnet MS/TP protocol.

An optional adapter and the free EE-PCS Product Configuration Software facilitate the configuration and adjustment of the EE820.
