EGE Elektronik Sensor for Explosive Productseries ST 103 KH

Description

EGE Elektronik Sensor for Explosive Productseries ST 103 KH is the authoritative choice for plant operators who need to monitor media flow within potentially explosive atmospheres without compromising on temperature resistance. In sectors like petrochemical refining and chemical synthesis, the combination of flammable vapors and extreme heat creates a high-risk environment. The ST 103 KH addresses this with a specialized thermal decoupling neck that protects the internal sensing electronics from continuous media temperatures of 120°C.
