Page 7: Application
(Equipment monitoring) Table 2 Response grades – temperatures 2.4 Static operating principle The measurement principle of the SKM-03.2 is based on measuring temperature-related resistance change. The sensor element consists of a 2-core coaxial cable. The insulating layer between the inner conductor and the cable shielding consists of a semiconductor with increasing conductivity when exposed to heat. -
Page 8: Description Of Components
The lines care routed through the housing and connected to the control circuit board. The function of the control unit is bundled on the SKM-03.2 control circuit board. Optical indicators for operation, fault and alarm are routed through a front panel and to the top of the front panel using light guides, with the transparent housing cover ensuring they are visible. -
