Probes for Cryogenic Turbo Pumps

Philtec builds custom displacement sensor systems to meet application requirements, which often include extreme environments. This month we delivered 8 sensors having 200 KHz bandwidth (sensor speed). The probe tips are threaded and connectorized so they may be separated from the sensor electronics.

Probes are Connectorized to the Electronic Modules 
Probe Tips are Immersed in LOX at -300°F and 1,000 psi

High Pressure Applications

There are three options for sealing the leak path thru the fibers under pressure:

1. Epoxy filled tips

2. Sapphire Windows epoxied into tip counterbores

3. Sapphire Windows brazed into tip counterbores

The best solution for an application depends upon several factors such as: the size of the fiber bundle, the dimensions of the probe tip, as well as the amount of applied pressure. Pressure can be static, reciprocating or pulsing. Extreme temperatures can be coupled with high pressures, and the probes could be submerged in oils or cryogenic fluids. Effectiveness of the seal and cost are major considerations. Philtec engineers can assist with the choice and design of the probe.
