资料下载The Unitec SENS-IT sensors are innovative, compact and low cost devices for environmental air quality monitoring. Based onUnitec proprietary technology, each SENS-IT sensor is specific for a single pollutant gas (CO, NO2 , O3 , C6H6 …) with extremely high sensitivity and selectivity (also at low ppb levels). Each sensor is engineered in an anodized aluminum case with new embedded electronic board for totally digital control of sensor performances. The RS485 interface permits to easily integrate the sensors in existing devices or monitoring networks, control digitally all the functioning parameters and calibrate them also from remote. The SENS-IT sensors exploits the advantages of the Thick Film Metal Oxide Semiconductor Technology (TF-MOS) for CO, NO2, O3, C6H6, and CH4 monitoring. The active surface of the sensor is based on a specific nano-structured semiconductor metal oxide. The first reaction which happens on the surface of the sensor is the adsorption of atmospheric oxygen with consequent charge transfer from semiconductor to oxygen molecules. The second reaction is related to specific gas to monitor, which while reacts with adsorbed oxygen (through Red-Ox reactions) allows the electrons to be released in the conduction band of the semiconductor. Taking the current signals from the sensors during these reactions, the direct concentration of the specific gas can be measured. Selectivity and sensitivity are reached using special doped semiconductor metal oxides, in addition, the stability and no consumption of active surface guarantees long term high repeatability and low maintenance needs. Monitoring of SO2, H2S, NH3, VOC, CO2 is also available using SENS-IT sensors based on traditional Electrochemical Technology (EC) or Infrared Technology (IR).
Gill TFT风显示器-中文彩页
简介:多功能 TFT 风显示器可以在气象(N-E-S-W) 或海洋(左舷/右舷)模式下显示风速和风向。 风信息显示采用8.5英寸LED背光,工业级液晶屏,以170°真视角显示数据。 多功能 TFT 风显示器在 NMEA 模式下直接从风传感器接收数据,无需额外的接口。 它为风传感器提供电源,并且可以“菊花链”到第二个风显示器以传输风传感器信息。
