插件 空气 OEM应用程序

气候变送器PFT28Ka•测量温度和相对湿度•从传感器到评估电子的数字信号传输•几秒钟的响应时间•传感器的易互换性•字母数字LCD显示•模拟输出0/2…10V或0/4…20 mA • Supply voltage 15...30 Vdc or 24 Vac (± 15%) • Compact plastic housing Protection class IP54; UL 94 HB • Measuring range relative humidity 0 ... 100% (short term condensation possible) • Measuring range temperature -30...+ 50 °C, 0...50 °C, 0...100 °C • Calculation and display of dew point temperature, enthalpy wet bulb temperature and absolute humidity The transducer PFT28Ka converts the measured variables of temperature and relative humidity into the following parameters: dewpoint temperature, absolute humidity, moisture ball temperature and enthalpy. The device has two analog outputs: Output 1 supplies the temperature signal and one of four further measured variables can be applied to output 2 via two-pole DIP switches. For direct display of the measured value, measured value and unit, the device has a two-line alphanumeric display. Different versions are available: A room sensor for wall mounting, a duct sensor for installation in a ventilation duct and a cable management variant with 2 m cable. In both versions, the sensor tube is installed directly on the housing. The output signals can be switched from 0/2 ... 10 V to 0/4 ... 20 mA with a plug-in bridge. The device is supplied with 15 ... 30 Vdc or 24 Vac.
