Kiel Probes

Kiel probes are designed to measure the total pressure with insensitivity to wind yaw and pitch angle. Used in a wide range of applications, they have become particularly popular used in arrays known as “rakes” in Formula One.

We can provide anything from individual probes, large quantities of removeable Kiels for an array, or a fully designed rake which combines other sensors such as thermocouples.
