Wet Bulb Temperature Transmitter

Hms112 outdoor humidity dew point wet bulb enthalpy and temperature transmitter for hvac current loop or modbus 2 accuracy.

Wet bulb temperature transmitter.

The 3 wire hms83 transmitter measures relative humidity and temperature in outdoor environments. The wet bulb temperature wbt is the temperature read by a thermometer covered in water soaked cloth wet bulb thermometer over which air is passed. This differs from the heat index which takes into consideration temperature and humidity and is calculated for shady areas. It is typically measured with either a psychrometer or a glass bulb thermometer wrapped in a wet cloth.

Temperature humidity wind speed sun angle and cloud cover solar radiation. Model wb4 wet bulb transmitters are rugged compact and ideally suited for monitoring wet bulb in building automation and process applications. The analog vaisala hms112 humidity and temperature transmitter is designed for accurate humidity and temperature measurements outdoors. Hms83 outdoor humidity dew point wet bulb enthalpy and temperature sensor for hvac and cooling towers voltage outputs 3 accuracy.

At kele we make it easy to find the right humidity product. Relative humidity dew point frost point wet bulb temperature enthalpy absolute humidity mixing ratio vapor pressure and. A wet bulb temperature is the lowest measurement of air temperature that results from evaporative cooling and it can be thought of as the temperature that wet skin feels when exposed to moving air. The hmt120 is delivered with a weather shield for the transmitter unit to protect it from the outdoor elements.

The hmt120 is designed for relative humidity and temperature monitoring in cleanrooms and it is also well suited for demanding hvac applications. At 100 relative humidity the wet bulb temperature is equal to the air temperature dry bulb temperature. The wetbulb globe temperature wbgt is a measure of the heat stress in direct sunlight which takes into account. The humidity parameter options available are.

At lower humidity the wet bulb temperature is lower than dry bulb temperature because of evaporative cooling. Optional outputs dew point wet bulb temperature and enthalpy can be easily selected by a single dip switch. Hmt120 cleanroom and hvac relative humidity dewpoint wet bulb enthalpy and temperature transmitter with exchangeable probe wall model current loop 1 5 rh 0 1 c accuracy. Hmt120 wet bulb dry bulb transmitter for cooling towers current loop.

Maintaining measurement traceability is easy due to field exchangeable intelligent measurement probes. Multifunction humidity temperature transmitter ge dew point enthalpy wet bulb transmitters and more building automation products available to ship.
