Snow Temperature profiler

DESCRIPTION

Temperature profiler for snow cover, made with a pole in anodized aluminium and white painted and with 12 high accuracy temperature sensors (Pt100 1/5 DIN) places on adjustable and removable arms up to 25cm away from border pole, to appreciate small temperature differences between the various points. The measurements start from ground level up to a maximum of 250 cm height. The arms with the sensors mounted on their head, are arranged radially around the pole, to reduce the physical interference among them and ensure that each sensor is fully immersed in the snow at its corresponding level. Each arm is also installed with a specific angle (about 10°) that limits the stay of snow in its surface during the denouement.
The distance between the individual sensors changes according to the height from the ground. All sensors are inserted in a special terminal in Teflon and are easily interchangeable thanks to a special IP68 screwed connector.
The sturdy structure, fixed to a base thanks to a special plate, is designed for cable routing. All sensors have a 4-wire cable and can be connected to an acquisition system via terminals.
