Description

EGE Elektronik Sensors with Integrated Amplifier Productseries ST 5021/1 KH is the authoritative choice for flow control in environments where standard sensors would suffer thermal failure. The “KH” designation represents a specialized engineering approach: the sensor uses a thermal decoupling neck that physically separates the sensing probe from the electronic housing. This ensures that even when the probe is submerged in 120°C media, the integrated amplifier remains at a stable operating temperature. Operating on the thermodynamic principle, the ST 5021/1 KH monitors flow velocity without the use of moving parts. This is a critical advantage in high-temperature cycles; traditional mechanical flow switches often seize, warp, or experience spring fatigue due to the high thermal expansion of metal components. The ST 5021/1 KH eliminates these mechanical failure points, offering a “fit-and-forget” solution for the most demanding thermal loops.
