Wet bulb temperature transmitter.

Model wb4 wet bulb transmitters are rugged compact and ideally suited for monitoring wet bulb in building automation and process applications. The wet bulb temperature is the temperature read by a thermometer covered in water soaked cloth over which air is passed. 0 to 20 ma dc or 4 to 20 ma dc load resistance. Calibration can be difficult.

Two linear outputs provide a 4 20 ma signal for dew point wet bulb or enthalpy and a 4 20 ma signal for dry bulb temperature. Multifunction humidity temperature transmitter ge dew point enthalpy wet bulb transmitters and more building automation products available to ship. It is therefore measured by wrapping a wet wick around the bulb of a thermometer and the measured temperature corresponds to the wet bulb temperature. Using a capacitive rh sensor the units s microprocessor computes the dew point wet bulb or enthalpy.

Using a capacitive rh sensor and an rtd temperature sensor the unit s microprocessor computes the dew point wet bulb or enthalpy. Temperature humidity transmitter temperature humidity transmitter tht 500 using dry and wet bulb sensors input output. Slow reaction to changes in temperature is due to the time required by the water supply to adapt. At kele we make it easy to find the right humidity product.

Optional outputs dew point wet bulb temperature and enthalpy can be easily selected by a single dip switch or can be ordered preconfigured. Using a capacitive rh sensor and an rtd temperature sensor the unit s microprocessor computes the wet bulb. Temperature 0 to 100 and wet bulb input temperature 0 to 100. The dry bulb temperature is the ambient temperature.

The hms82 transmitter is optimized for outdoor use. General lab and industrial. Pce wb 20sd is a multifunction wet bulb temperature data logger used to measure indoor outdoor wet bulb globe temperature wbgt black globe temperature tg wet bulb temperature wb dew point temperature air. At 100 relative humidity the wet bulb temperature is equal to the air temperature.

Wet bulb temperature is the lowest temperature to which air can be cooled by the evaporation of water into the air at a constant pressure. The wet bulb temperature is defined as the temperature of a parcel of air cooled to saturation by the evaporation of water into it with the latent heat supplied by the. The 2 wire hms82 transmitter measures relative humidity and temperature in outside air osa. The wet bulb temperature reacts slowly to changes in humidity because of the mass of the wet bulb thermometer and wick.

At lower humidity the wet bulb temperature is lower than dry bulb temperature because of evaporative cooling.
