Dew Point Temperature Sensor

The capacitive polymer sensor is bonded together with a temperature sensor and dew point is calculated from the humidity and temperature readings.

Dew point temperature sensor.

The high temperature tolerance of the sensor allows direct measurement from hot process without the need for a sampling system and sample conditioning. At 100 rh the ambient temperature equals the dewpoint temperature. Dew point transmitters multifunction humidity transmitters condensation sensors and more humidity products available to ship. The more negative the dewpoint is from the.

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. The ambient and sensor temperature is 1 deg c. The dew point temperature is always less than or equal to the air 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.

Vaisala s patented auto calibration function optimizes the measurement stability at low dew points. The dew point or dew point temperature indicates the air temperature at which the water contained in the air will condense. Dew point temperature td is the temperature at which air becomes saturated with water and begins to condense forming dew. Dew point sensors are used to measure and monitor the dew point temperature.

The sensor is heated at regular intervals during the automated auto calibration procedure. At the dew point the relative humidity is 100 at constant pressure. At this point the air cannot hold more water in the gas form. The dew point is the lowest temperature that allows water vapour to remain in a gas without condensing to a liquid state.

At kele we make it easy to find the right humidity 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. So remember to check the dew point in your morning weather report. Dew point varies depending on the amount of water vapor present in the air with more humid air resulting in a higher dew point than dry air.

Dew point is simply the temperature at which the water vapor condensates to liquid water. 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. 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.
