Dew Point Temperature Sensor

The more negative the dewpoint is from the.

Dew point temperature sensor.

The dew point temperature is always less than or equal to the air temperature. Vaisala s patented auto calibration function optimizes the measurement stability at low dew points. Furthermore the higher the relative humidity the closer the dew point to the current air temperature with 100 relative humidity meaning that dew point is equivalent to the current temperature. The dew point is the temperature the air needs to be cooled to at constant pressure in order to achieve a relative humidity rh of 100.

Dew point is simply the temperature at which the water vapor condensates to liquid water. The high temperature tolerance of the sensor allows direct measurement from hot process without the need for a sampling system and sample conditioning. The capacitive polymer sensor is bonded together with a temperature sensor and dew point is calculated from the humidity and temperature readings. At kele we make it easy to find the right humidity product.

The wide dynamic rage of the measurement in dmt345 and dmt346 is unique. The ambient and sensor temperature is 1 deg c. As the air or gas temperature drops its ability to absorb water vapour drops until it becomes completely saturated and below this dew point temperature water droplets will start to form. The dew point is the temperature to which air must be cooled to become saturated with water vapor when cooled further the airborne water vapor will condense to form liquid water when air cools to its dew point through contact with a surface that is colder than the air water will condense on the surface.

The sensor is heated at regular intervals during the automated auto calibration procedure. The dew point is the lowest temperature that allows water vapour to remain in a gas without condensing to a liquid state. At 100 rh the ambient temperature equals the dewpoint temperature. If this occurs in a compressed air system for example this can lead to damage to the system and loss of quality in the end product.

Measurements can be made from 40 c frost point up to 100 c dew point with dry bulb temperatures ranging up to 350 c. Dew point transmitters multifunction humidity transmitters condensation sensors and more humidity products available to ship. At this point the air cannot hold more water in the gas form. The dew point or dew point temperature indicates the air temperature at which the water contained in the air will condense.

So remember to check the dew point in your morning weather report. Dew point sensors are used to measure and monitor the dew point temperature. At the dew point the relative humidity is 100 at constant pressure.
