Relative humidity and temperature sensor PFT28K

duct-mountdew-pointdigital

• Measuring temperature and relative humidity with a „single-chip“-sensor • Calculation and display of dew point temperature, enthalpy, wet bulb temperature and absolute humidity • Digital transmission from sensor to the evaluation electronics • Fast response time • Exchange ability of sensor without recalibration • Alphanumeric LCD-indicator for: temperature, relative humidity, dew point temperature, absolute humidity, wet bulb temperature and enthalpy • Analog outputs 0/2…10 V or 0/4…20 mA The transmitter PFT28 converts the measured variables temperature and relative humidity into the measured variables: dew point temperature, absolute humidity, wet bulb temperature and enthalpy. Output 1 supplies the temperature signal while Output 2 can be assigned to one of four other measured variables. The second measured variable is selected by a two-pole DIP switch. Measured variable, measured value and unit are displayed on a two-line alphanumeric display. Two PFT28 versions are available: A room sensor for wall mounting and a duct sensor for installation in a ventilation duct. In both versions, the sensor tube is mounted directly to the chassis. With a jumper, the output signals can be switched from 0/2…10 V to 0/4…20 mA. The device is powered with 15…30 Vdc or 24 Vac.
