µCAT Measuring Head for Low Radial Clearance

While our SCAT and LCAT measuring heads can be used with a wide range of turbine brush-seal grooves, the latest µCAT ("mu-CAT" or "micro CAT") fits where the others can't. The latest turbines for power generation being developed include stages with very small radial clearance. The µCAT can fit in the same width slot as the SCAT (0.500") and measure radial clearances from 0.200" to 0.250".

We have replaced this model with one that fits brush-seal grooves as narrow as 0.300". Look for an update soon.

Step #2

Attach Tape
Attach the head to the end of the tape using the tape clip with the wire retainer to secure the end of the tape to the head.

Step #3

SCAT at 9:00
Insert the head into the packing slot by depressing the lever arm.

Step #4

SCAT at 3:00 position00.0 meter
Pull the head to the 3:00 o’clock position using the tape measure and then “zero” the meter using the coarse adjustment on the head and the fine adjustment on the power supply.

Step #5

SCAT at 6:00 position-10.4 meter
Pull the head to the 6:00 o’clock position using the cable and take the reading.
