In practice , based on the affinity of vapor capacitive

In practice , based on the affinity of vapor capacitive, resistive or conductive thin film as a humidity sensor is sensitive to humidity , but also on the temperature-sensitive , so in order to achieve accurate measurement , or wide temperature range , temperature compensation is not necessary small. To achieve temperature compensation, temperature measurements must be placed as close to the humidity sensor measurement environment, particularly humidity and temperature is calculated using the dew point , which is particularly important. Industrial humidity and dew point measuring apparatus is usually integrated in the sensor substrate opposite a 1000 ohm platinum RTD temperature Crankshaft Position Sensor Replacement for temperature compensation.When the sensor sensing area surface temperature is below ambient dew point temperature , thenCrankshaft Position Sensor sensing area surface condensation is easy , even if the surface temperature or sensor sensing area within the local temperature only briefly below ambient dew point temperature, the sensor has an internal or surface condensation may form , especially when the working environment humidity above 95 %, the temperature of the subtle fluctuations are likely to cause condensation .In order to avoid humidity and dew condensation on the humidity sensor influence , there is usually some measures such as maintaining good air circulation to reduce temperature fluctuations ; add to the humidity sensor sintered stainless steel filter , a waterproof coating to further suppress the condensation of .
