High-temperature measurement is a challenging prospect. Sensing elements must be robust enough to withstand the heat without degrading. Yet they also need the right conductivity to ensure measurement accuracy. Crucially: This conductivity must stay consistent across broad temperature ranges. Finding the right material for sensor surfaces is thus a balancing act.
Platinum is so often a standout material for high-temperature processes. It is routinely applied as a metal substrate in high-sensitivity sensing applications. But why? This article explores the benefits of platinum metal surfaces in more depth.
