PHILTEC

What PHILTEC does

PHILTEC, Inc. is a privately held manufacturer of custom fiber optic displacement sensor systems headquartered in Annapolis, Maryland, in continuous operation since 1988. The company's core technology uses retro-reflective fiber optic measurement to deliver non-contact displacement, vibration, and position sensing in environments where electrical or acoustic sensors fail — including cryogenic liquids (down to single-digit Kelvin), ultra-high vacuum (down to 10^-11 Torr), high pressure (up to 30,000 psi), high magnetic fields (several Tesla), and extreme temperatures (-420°F to +800°C). The product portfolio centers on two sensor architectures: D Model sensors (reflectance dependent) optimized for high-speed dynamic measurements up to 1 MHz, and RC Model sensors (reflectance compensated) for accurate position readings on rotating or varying-reflectivity targets, supported by DMS amplifiers with analog, RS232, USB, and WiFi outputs, vacuum passthru hardware, replaceable sensor tips, and a range of fiber optic cable jackets.

The business operates on a custom-engineered, project-driven model in which over 70% of products are configured to specific customer hardware and environmental requirements, with standard units delivered in two weeks and custom units in 6-8 weeks. Pricing is quote-based and not publicly disclosed. Revenue is generated primarily through hardware sales of sensor systems and amplifiers, complemented by accessories and NIST-traceable calibration services. PHILTEC sells direct in the United States through its Annapolis office and reaches international markets through a network of 25+ specialized instrumentation distributors across North America, Europe, and Asia-Pacific.

The customer base is concentrated in technically demanding sectors: aerospace (flight testing, rocket turbopumps, satellite propulsion, jet engines), cryogenics (liquid hydrogen, oxygen, and nitrogen systems), energy and turbomachinery (turbine blade clearance), medical and MRI (superconducting magnet monitoring), high-pressure industrial testing, and ultra-high vacuum research. Named customers and end-users include NASA Marshall Space Flight Center, the European Space Agency (Sentinel 3 Satellite program), Airbus (A380 thrust reverser testing), and senior engineers on a Space Launch Vehicle program. The company markets through an engineering-led approach centered on technical documentation, application notes, and direct field engagement rather than broad consumer advertising.

Core offering

PHILTEC designs and manufactures custom fiber optic displacement sensor systems used for non-contact measurement of displacement, vibration, and position in extreme environments. The portfolio includes D Model (Reflectance Dependent) and RC Model (Reflectance Compensated) sensor probes, amplifiers with analog/digital/wireless outputs, vacuum feedthrough hardware, sensor tips, fiber optic cables, and the CMS3400 wireless turbine clearance measurement system. Over 70% of units are custom engineered for specific customer applications such as cryogenic, ultra-high vacuum, high pressure, high magnetic field, and high temperature environments.

Product overview

PHILTEC is a manufacturer of custom fiber optic displacement sensor systems based in Annapolis, Maryland, operating since 1988. The product portfolio centers on two core sensor technologies: D Model Sensors (Reflectance Dependent) for fast dynamic operations parallel to the probe axis, and RC Model Sensors (Reflectance Compensated) for accurate position measurement on rotating or varying-reflectivity targets. These sensors integrate with supporting hardware including DMS Amplifiers (offering analog 0-5V, USB, RS232, or WiFi output), Vacuum Passthru Hardware (rated from 10^-4 to 10^-11 Torr), Replaceable Sensor Tips, and Fiber Optic Cables with various jacket options. The CMS3400 Wireless Measurement System extends the portfolio for turbine blade clearance applications. An interactive Sensor Configurator and DMS Control Software enable system configuration and data acquisition.
