FIBER OPTIC SENSOR OPTIONS

Why Use Fiber Optic Distance Sensors?

• Contactless
► No effect on the target
• Small size
► Small probes, small measuring spot size
• Configurable
► Customized access for hard-to-reach targets
• Customizable to
► Air, gas or liquid atmospheres
► Cryogenics
► Vacuum
• Optical fiber
► Intrinsically safe
► EMF immunity
► Vibration and shock resistant
► High speed
• Measuring range
► 0 – 75mm
• Resolution
► Sub micron

By clicking on the option letter in the table below you can access the description of many of these options.

The standard PHILTEC sensor package includes a stainless steel sensor tip, 3 foot PVC jacketed fiber optic cable and a DC 20 KHz bandwidth booster or strain gauge signal processing unit as an integrated unit with the fiber optic cable potted in the electronics housing.

Many options are available where the sensor tip, fiber optic cable and/or sensor electronics can be customized. Multiple options can be combined into one unit and specified in the following format: model D100-BC1LT for analog devices or model DMS-RC100-BC1LT for digital devices.

Important NOTE:

It should be noted that certain combinations of options are not possible on all models.

For example, it doesn’t make sense to expect high frequency response when combining interchangeable tips with long fiber optic cables and dark targets.

Please contact us if you have any questions on such topics.
