Capacitive Sensors: Custom Probes
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.
Some existing custom capacitive sensors are shown in the table below. The designs here will usually work with the CPL190/290, CPL230 and CPA100 drivers. Contact one of our Application Engineers or local representatives for help in getting the right sensor for your application.
