E+E变送器EE850系列介绍
EE850 在一个创新的外壳中结合了 CO2、相对湿度 (RH) 和温度 (T) 测量。 它是按需控制通风和楼宇自动化的选择。 由于 CO2 测量范围高达 10 000 ppm 和 T 工作范围 -20...+60 °C (-4...+140 °F)，EE850 也可用于要求苛刻的气候和过程控制。
长期稳定性
EE850 采用 E+E 双波长 NDIR CO2 传感器，可补偿老化效应，对污染高度不敏感，并提供出色的长期稳定性。 E+E 专有涂层保护 RH 传感元件免受灰尘、污垢和腐蚀的影响。
测量精度高
多点 CO2 和 T 工厂调整程序可在整个 T 工作范围内实现出色的 CO2 测量精度。
模拟、数字和无源 T 输出
CO2、RH 和 T 测量数据以及计算的露点温度 (Td) 可在各种模拟输出上获得。 此外，采用 Modbus RTU 或 BACnet MS/TP 协议的 RS485 接口还提供其他参数，例如绝对湿度 (dv)、混合比 (r)、水蒸气分压 (e) 或焓 (h)。
简单的配置和调整
可选的适配器和免费的 EE-PCS 配置软件有助于 EE850 的配置和调整。
The EE850 combines CO2, relative humidity (RH) and temperature (T) measurement in an innovative enclosure. It is ideal for demand controlled ventilation and building automation. Due to the CO2 measuring range up to 10 000 ppm and T working range -20...+60 °C (-4...+140 °F), the EE850 can be employed also in demanding climate and process control.
Long-Term Stability
The EE850 incorporates the E+E dual wavelength NDIR CO2 sensor, which compensates for ageing effects, is highly insensitive to pollution and offers outstanding long term stability. The RH sensing element is protected against dust, dirt and corrosion by the E+E proprietary coating.
High Measurement Accuracy
A multiple point CO2 and T factory adjustment procedure leads to excellent CO2 measurement accuracy over the entire T working range.
Analogue, Digital and Passive T Outputs
The CO2, RH and T measured data as well as the calculated dew point temperature (Td) are available on various analogue outputs. Additionally, the RS485 interface with Modbus RTU or BACnet MS/TP protocol supplies also other parameters such as absolute humidity (dv), mixing ratio (r), water vapor partial pressure (e) or enthalpy (h).
Easy Configuration and Adjustment
An optional adapter and the free EE-PCS configuration software facilitate the configuration and adjustment of the EE850.
