Problem Quartz fibers have excellent transmission over long lengths, but they are very expensive, so usually cost prohibitive. A customer recently asked for a model D171 sensor with 45-meter length for displacement measurements in vacuum and high magnetic field. Solution PHILTEC devised a 3-piece cost saving system, where only 10% of the model D171 probe … Continue reading
Where it is desirable to separate the sensor electronics from the measuring probes, fiber optic cables can be connectorized using PHILTEC’s simple knurled finger tight design. Some reasons for connectorized fiber optic cables: Easy replacement of damaged tips Substitution of alternate tips Removal of electronics from machinery without removing sensor tips Interchangeability of different tips … Continue reading
The Euclid Satellite project is a good example of how PHILTEC’s sensors work with excellent results in cryogenic conditions. This month PHILTEC again delivered sensor systems for space telescope lens distortion testing measurements. These are 2-channel fiber optic displacement sensor systems (see image above) designed for 3.2 mm operation in vacuum. The delivered seven 2-channel … Continue reading
Background An axial-flow pump (AFP) is a common type of pump that essentially consists of a propeller (an axial impeller) in a pipe. Cryogenic turbopumps (CTP) are the heart of a rocket engine. With today’s generation of reusable heavy launch space vehicles, CTPs supply pressurized subcooled fuel and oxidizer fluids, which mix and ignite to … Continue reading
PHILTEC specializes in the design of fiber optic sensor systems for gaining access to hard-to-reach targets. In March 2019, several dozen model D47 sensors were delivered with long fiber optic cables and very small 90° probes as seen here. The fiber optic cable lengths varied from 21 ft (6.4 m) to 55 ft (16.8 m). … Continue reading
It’s not often we discover how well PHILTEC sensors perform for customers. The Euclid Satellite project is a good example of their sensors being used with excellent results in cryogenic conditions. A technical paper published in 2012 describes how PHILTEC’s high precision sensors were successfully used at 150°K to verify the distortion of lens holders to … Continue reading
