+: F for ∆RN/RN = ± 1 % H for ∆RN/RN = ± 3 % J for ∆RN/RN = ± 5 % Note The type series S 862 has a specially designed insulation (coating, wire coating) to withstand the immersion test in water of 1000 h/25 °C. Therefore these sensors must be protected to avoid any damage of the insulation material during handling and in the application.
