Wet Bulb Temperature Transmitter

The hmt120 is delivered with a weather shield for the transmitter unit to protect it from the outdoor elements.

Wet bulb temperature transmitter.

The analog vaisala hms112 humidity and temperature transmitter is designed for accurate humidity and temperature measurements outdoors. The wetbulb globe temperature wbgt is a measure of the heat stress in direct sunlight which takes into account. Hmt120 wet bulb dry bulb transmitter for cooling towers current loop. Using a capacitive rh sensor and an rtd temperature sensor the unit s microprocessor computes the wet bulb.

At 100 relative humidity the wet bulb temperature is equal to the air temperature dry bulb temperature. 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. Optional outputs dew point wet bulb temperature and enthalpy can be easily selected by a single dip switch. 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.

Hms83 outdoor humidity dew point wet bulb enthalpy and temperature sensor for hvac and cooling towers voltage outputs 3 accuracy. These can be exchanged with minimal downtime and process disturbance. At kele we make it easy to find the right humidity product. At lower humidity the wet bulb temperature is lower than dry bulb temperature because of evaporative cooling.

Multifunction humidity temperature transmitter ge dew point enthalpy wet bulb transmitters and more building automation products available to ship. 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. The humidity parameter options available are.

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

Relative humidity dew point frost point wet bulb temperature enthalpy absolute humidity mixing ratio vapor pressure and. Maintaining measurement traceability is easy due to field exchangeable intelligent measurement probes.
