Eddy-Current: Custom Probes
Simple Eddy-Current Probe Modifications
Sometimes you just need to change a basic characteristic of the probe. Some basic and frequent customizations include:
- Cable Length Changes
- Extended Sensing Tips
- Material Changes
- Extended Temperature Ranges
Fully Customized Eddy-Current Probes
You may need a complete custom design to fit your application. We’ve done this many times using our CUSTomer-Oriented Manufacturing (CUSTOM) system – a streamlined process that creates custom eddy-current sensors as quickly as possible. The table below shows some past designs. If one of these designs will work for you, charges for customization will be reduced or eliminated. Contact one of our Application Engineers or local representatives for help in getting the right sensor for your application.
Use Existing Custom Designs
You can save some or all of the time and cost of designing and testing a new custom probe if an existing custom probe design will work for you.
