Note
The type series G1565 has a specially designed insulation (coating, wire coating) to withstand the
named media tests. Therefore these sensors must be protected to avoid any damage of the
insulation material during handling and in the application. The non-insulated area of the NTC
element must not have contact with the media or vapor thereof.
