Kaman Sensors
The World's Leader in High-Performance Noncontact Position Sensors
Kaman specializes in inductive, eddy current technology. Kaman sensors provide non-contact indication of linear position/ displacement by outputting an analog voltage, or, in some cases, a current that is proportional to the distance between the sensor face and the target being sensed.
Eddy current technology requires an electrically conductive target. It does not need to be a grounded target, and performance is typically the same whether the target is ferrous or non-ferrous.
Below are standard sensor and signal conditioning solutions for most applications. Kaman can also customize sensors to meet application specific requirements.
Please contact Kemp Instruments for assistance with selecting the right sensor for your application.
