EE211高湿多参数显示温湿度传感器
EE211温湿度仪

应用在持续高湿环境的温湿度变送器
EE211致力于苛刻环境控制应用中对持续高湿(>85%RH)和结露状态下对温湿度进行精密可靠和长期稳定的测量。
产品配备一个湿度测量探头和一个可更换的温度测量探头,在高湿状态下,湿度测量探头具备自动加热功能。即使在污染侵蚀的环境中,EE211仍能保持优秀的性能,这主要得益于我们将位于探头内的测量电路和具有长期稳定性能的HCT01敏感元件有效地组合在一起,同时,对测量电路采取完全密闭的封装保护措施,并对HCT01敏感元件进行镀膜保护。
EE211外壳防护等级为IP65/NEMA 4,显著降低了安装成本,并同时提供出色的抗污染和冷凝的保护。所有的测量参数都可以通过 Modbus RTU 数字接口获得,而其中的任意两个值可通过模拟信号以电压或电流 (三线)形式的输出。此外,在可选的带背光显示屏上最多可同时显示三个测量参数值。
使用附加的专用组态工具,用户可以对变送器进行参数选择和量程设置,并对变送器的温度和湿度进行单点或两点校准。同时,也可以对温度探头进行单独校准;对于金属外壳的温度探头,还可以用高精度干体炉对其进行校准。
典型应用
- 果蔬存储
- 气调库和环境试验箱
- 绿色大棚、孵化室和食用菌行业

Humidity and Temperature Transmitter for Continuous High Humidity
The EE211 is dedicated for accurate and long term stable measurement under continuous high humidity (>85 % RH) and condensing conditions in demanding climate control.
It features a heated humidity probe and an interchangeable temperature probe. Excellent performance of EE211 even in polluted, aggressive environment is ensured by the combination of completely encapsulated measurement electronics inside the humidity probe and the long-term stable HCT01 sensor with E+E proprietary coating.
The EE211 enclosure is rated IP65/NEMA 4, minimizes installation costs and provides outstanding protection against pollution and condensation. All measured and calculated values are available on the Modbus RTU interface whereas two of the values are available on the analogue voltage or current (3-wire) output. Additionally up to three values can be shown simultaneously on the optional illuminated display.
With the optional product configuration adapter EE-PCA the user can set the Modbus RTU interface parameters, the display format, the measured parameters and the output scaling. Furthermore, the user can perform an one or two point humidity and temperature adjustment. The T probe can also be adjusted separate; for the metal version of the T probe the reference can be a high accuracy dry block calibrator.
