A dew point transmitter, also known as a dew point sensor or hygrometer, is an instrument used to measure the dew point temperature of a gas or air mixture. The dew point is the temperature at which air becomes saturated with water vapor, causing condensation to form. 7382708685 The transmitter typically consists of a sensing element that measures the humidity of the gas and a temperature sensor. The humidity sensor measures the partial pressure of water vapor in the gas, and the temperature sensor measures the temperature of the gas. By combining these measurements, the transmitter can calcu
