Wet Bulb Temperature Transmitter

This differs from the heat index which takes into consideration temperature and humidity and is calculated for shady areas.

Wet bulb temperature transmitter.

Hms112 outdoor humidity dew point wet bulb enthalpy and temperature transmitter for hvac current loop or modbus 2 accuracy. The 3 wire hms83 transmitter measures relative humidity and temperature in outdoor environments. Model wb4 wet bulb transmitters are rugged compact and ideally suited for monitoring wet bulb in building automation and process applications. Using a capacitive rh sensor and an rtd temperature sensor the unit s microprocessor computes the wet bulb.

The wetbulb globe temperature wbgt is a measure of the heat stress in direct sunlight which takes into account. At kele we make it easy to find the right humidity product. Hmt120 wet bulb dry bulb transmitter for cooling towers current loop. The humidity parameter options available are.

Optional outputs dew point wet bulb temperature and enthalpy can be easily selected by a single dip switch. Multifunction humidity temperature transmitter ge dew point enthalpy wet bulb transmitters and more building automation products available to ship. The hmt120 is delivered with a weather shield for the transmitter unit to protect it from the outdoor elements. Relative humidity dew point frost point wet bulb temperature enthalpy absolute humidity mixing ratio vapor pressure and.

At 100 relative humidity the wet bulb temperature is equal to the air temperature dry bulb temperature. These can be exchanged with minimal downtime and process disturbance. It is typically measured with either a psychrometer or a glass bulb thermometer wrapped in a wet cloth. Maintaining measurement traceability is easy due to field exchangeable intelligent measurement probes.

At lower humidity the wet bulb temperature is lower than dry bulb temperature because of evaporative cooling. The hmt120 is designed for relative humidity and temperature monitoring in cleanrooms and it is also well suited for demanding hvac 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.

The hmt120 is intended for outdoor wet dry bulb measurements in hvac cooling tower applications. Temperature humidity wind speed sun angle and cloud cover solar radiation.
