EGE Elektronik Sensor with Integrated Amplifier Productseries ST 5021/2 KH

Description

EGE Elektronik Sensors with Integrated Amplifier Productseries ST 5021/2 KH is the authoritative choice for flow control where standard sensors fail due to thermal stress. The “KH” designation identifies this unit as a high-temperature specialist, featuring advanced thermal decoupling and high-grade internal components that allow the integrated electronics to function perfectly while the probe is immersed in fluids up to 120°C. Operating on the thermodynamic principle, the ST 5021/2 KH utilizes a solid-state probe to monitor flow velocity. This technology is uniquely suited for high-temperature cycles because it contains no moving parts. Traditional mechanical switches often seize or suffer from material fatigue due to the expansion and contraction of metal parts in hot media; the ST 5021/2 KH eliminates these failure points entirely, offering a maintenance-free life cycle.
