Solar Radiation, Air Temperature and RH% transducer

TTEPRHSO is a very solid and compact sensor, which allows to measure simultaneously air temperature, relative humidity and global solar radiation. It is featured by an extreme flexibility, which makes the sensor an excellent versatile device, suitable for
many different applications, ensuring at the same time high standards of performance in all the measurement fields. The air temperature sensing element is composed of a platinum Pt100 resistance thermometer with a response curve, compliant with the DIN 43760 Class 1/3 standard and 4-wire connection. The humidity measurement is given using a laser-cut capacitive polymer transducer connected to an electronic signal conditioning board, and a silicon cell detects solar radiation generating a tension proportional to the captured incident radiation.
Sensor body is made of anticorrosive aluminium alloy, and it is protected by an external non-hygroscopic and UV-stabilized plastic shield that assures also a ventilated environment for the sensing components.
TTEPRHSO is supplied with power and signal cable (4 m).
