EE800采用的E+E单光源双光束红外线测量技术可以自动进行光源老化补偿,并具有较高的抗污染能力,从而保证了产品出众的长期稳定性。在产品生产过程中,E+E工厂对CO2的浓度和温度进行了多点校准,使CO2变送器在全量程温度工作范围下获得了非常优秀的测量精度。
带标准模拟信号输出的EE800系列变送器同时可以附带一路被动温度电阻信号,并且有RS485附带物理接口,可以使用Modbus RTU和BACnetMS/TP通讯协议对绝对湿度、混合比、热焓、霜点温度和水蒸气分压力等参数进行输出。

The main difference is the hardware interface. The Modbus RTU protocol runs on RS485 Hardware while Modbus TCP/IP protocol on Ethernet hardware.
All BACnet products are tested at E+E. The BTL listed E+E products have been additionally tested by the BACnet Testing Laboratories.
Not at all. Do not temper in any way with the CO2 sensing cell. Please see the operation manual of the specific E+E CO2 measurement device.

All E+E CO2 measuring devices feature an auto-calibration function. For details please refer to "Princibles of CO2 measurement".
Yes, this in normal in several applications. It is the case for instance in new concrete buildings, due to the concrete carbonation effect. The calcium in the new concrete binds CO2 from the air.
The standard scope of supply of E+E CO2 sensors includes an inspection certificate according DIN EN 10204 - 2.2. For details on calibration certificates please see our white paper "Calibration and Traceability in Measuring Technology".
Accredited calibration certificate for CO2 is available upon request, please see our calibration website.
Transmitter with "two-wires" technology receive the power from the process, and the signal is carry on return wire (closed current loop). With technology "three-wires" the power supply is separate from current output: 2 wires are the power supply and third carry the signal.
