RCap X is quite simply industry disruptive. RCap X delivers sensitivity, working range, greater than 1MHz bandwidth and signal to noise ratios to a level never before seen – it’s in a class of its own. When you’ve been doing this as long as we have you know what it takes to make these claims and this delivers – it has no peers.

An extraordinary, high specification, active probe technology for high speed applications such as turbochargers or combined Blade Tip Timing and Clearance applications. It redefines Blade Tip Clearance measurement performance expectations, RCap X was recently featured in a peer reviewed ASME technical paper, for more information please visit our Technical Paper Library.

We’re so proud Rotatip disrupted the market in 1980 and Rotacap X will do again from 2020. RCap X is still currently application specific – there is a lead time, so please contact us to start your delivery.
