Room temperature sensor PFT25R (room sensor), measuring range: output 1: 30...+50 °C, output 2: customer specification required, measured medium: temperature and humidity
The PFT25 measuring transducer uses digital calculation to generate the variables frequently used in air conditioning technology from the directly measured variables of temperature and relative humidity: relative humidity, dew point temperature, absolute humidity, wet bulb temperature and enthalpy.
The PFT25 measuring transducer enables the conversion of directly measured temperature and relative humidity in air conditioning technology into various measured variables such as relative humidity, dew point temperature, absolute humidity, wet bulb temperature and enthalpy by means of digital calculation.
With two analog outputs, the temperature signal can be output on output 1 and a selected measured variable on output 2. All measured and calculated variables are displayed with a resolution of 12 bit and the mean air pressure of 1000 hPa is used for the calculation. In order to achieve maximum accuracy, the local altitude or mean air pressure should be specified on site.
