Custom Fiberoptic Sensors For Non-Contact Measurement of Linear Distance, Displacement and Vibration

Welcome to Philtec, Inc., a manufacturer of custom fiber optic displacement sensors. Based in Annapolis, Maryland, Philtec has been providing innovative fiber optic displacement sensing solutions since 1988. Philtec sensors are built in the USA and sold thru a global network of technical sales agents. Our engineers can help you design that special sensor uniquely meeting your application requirements.

About The Sensors....Read More
These are retro-reflective type optical devices. The sensors use bundled glass or quartz fibers to transmit light to and receive reflected light from target surfaces. The intensity of received light is processed and used to measure linear distances from 0 to 75 mm away. Applications include automated production gaging, dynamics of actuators, pistons & valves, shaft and rotor displacements, turbine blade clearance, as well as mechanisms or machinery operating in extreme environments from cryogenic to extremely high temperatures.

Use analog sensors for dynamic applications with speeds up to 1 Megahertz.
Digital systems are best suited for industrial automation applications requiring less than 5,000 samples per second.
