Rotacap Blade Tip Clearance measurement systems are available in a number of formats, the most cost effective form of supply is in separate components. Rotacap DAQ systems can be supplied within an internationally recognised National Instrumentation cRIO chassis. The cRIO chassis is a rugged, high performance control system which can be fitted with 8 measurement channels to offer class leading BTC measurement performance.

This configuration offers a low cost entry for academia and research institutes, or when test requirements allow. The DAQ system requires the connection to a windows based PC system to interface and store measurement data.

Rotacap DAQ hardware can acquire 8 channels of BTC Measurement data plus OPR simultaneously per unit. The DAQ system communicates over Ethernet and can multicast data to suit client requirements.

Separate OPR conditioning units can be supplied to condition most types of probe technologies to a TTL signal suitable for the NI c-RIO chassis input. A separate industrial PSU unit is supplied to power the NI chassis. This represents the lowest cost, lowest footprint entry system for BTC applications currently available.

We maintain an active development program in all the areas of the technology required in our solution and continue to enhance system performance and measurement. Rotadata are an AS9100:D & ISO9001 2015 accredited company, offering design and manufacture, project management and collection and delivery services expedited within the UK and world-wide through years of global shipping expertise.
