Showcase humidity and tempe­rature sensor

展示湿度和温度传感器

HYGRASGARD® VFF / VFTF

可校准湿度和温度传感器HYGR ASGARD® VFF / VFTF测量空气的相对湿度和温度。它将被测量的湿度和温度转换为0 - 10 V或4 ... 20 mA的标准信号，并可带/不带可选显示器。它配备了四个可切换的温度范围。相对湿度（％rH）是水蒸气分压除以相应气体温度下的饱和蒸气压的商。测量传感器设计用于精确检测温度和湿度。数字，长期稳定的传感器用作湿度和温度测量的测量元件。用户可以进行微调。展示传感器用于非侵蚀性，无尘环境，专门设计用于安装在天花板，墙壁，陈列柜或博物馆，画廊内的展示柜中，电影院或演讲厅或实验室。测量元件包含在不锈钢探头内，其低高度（约2.5 mm）使其几乎看不到。

测量范围湿度：0 ... 100％r。H。

The calibratable humidity and temperature sensor HYGRASGARD® VFF ⁄ VFTF measures the relative humidity and temperature of air. It converts the measurands humidity and temperature into a standard signal of 0 - 10 V or 4...20 mA, and is available with ⁄ without an optional display. It is equipped with four switchable temperature ranges. Relative humidity (in % r.H.) is the quotient of water vapour partial pressure divided by the saturation vapour pressure at the respective gas temperature. The measuring transducers are designed for exact detection of temperature and humidity. A digital, long-term stable sensor is used as a measuring element for humidity and temperature measurement. Fine adjustment by the user is possible. The showcase sensor is used in non-aggressive, dust-free environments and is specifically designed for installation in ceilings, walls, inside showcases or display cabinets in museums, galleries, cinemas or lecture halls or laboratories. The measuring element is contained inside a stainless steel probe and its low height (approx. 2.5 mm) makes it barely noticeable.

Measuring Range Humidity: 0...100 % r. H.
