Capacitive Sensors: Custom Probes

Custom Probe Examples down

Custom is Standard

Over half of our capacitive sensor orders are modified in some way; from simple custom calibration ranges to complete probe designs for a specific application, and everywhere in between.

Making It Work For You

In your application, getting a probe into the right place with the right sensing characteristics may require probe design changes. We've done this many times using our CUSTomer-Oriented Manufacturing (CUSTOM) system - a streamlined process to create custom capacitive sensors as quickly as possible.

Use Existing Custom Designs

If an existing custom probe design will work for you, you can save some or all of the time and cost of designing and testing a new custom probe. Maybe we already have a design for your need.

Contact one of our Application Engineers or local representatives for help in getting the right sensor for your application.
