The WE715 sensor is suitable for monitoring atmospheric temperature and relative humidity. Relative humidity indicates the percentage ratio between the quantity of vapor contained in an air mass and the quantity of saturation that the air volume can contain, under the same temperature and pressure conditions.
Normally, the trend of relative humidity is inverse to that of temperature. The sensor that detects humidity is able to measure its variations and is composed of a capacitive element and a linear amplifier, which provides an output of a 4-20mA electrical signal, proportional to the relative humidity. For outdoor use, a solar shield is available to protect the sensor from adverse weather conditions.
Every sensor is provided with a calibration certificate that attests the results of the test performed and all electromechanical features.
