The ET-3356 is a floor sensor for the combined measurement of temperature and humidity values in open spaces that can be driven on or walked on. It has a robust design made of brass and is fully encapsulated. Thanks to its very low height, it is particularly suitable for stairs, terraces, etc. The connection cable can be routed either downwards or to the side. Incl. 6 m connecting cable. Diameter 68 mm, height 31 mm (cable to the side) or 65 mm (cable downwards), load capacity 20 kN, temperature range -30 °C to °C, humidity measurement -20 °C to °C.
