METROL - Model DPA Series -Air Gap Sensor

The DPA series of air microsensors are non-contact, high-precision air sensors with a repeatability of ±0.5µm and the ability to check for adhesion, unlike conventional air gap sensors that are only able to check for presence or absence. It is used for detecting "float" of a few microns due to cutting chips during workpiece clamping, for internal diameter inspection, and for automatic positioning of rotating wheels on CNC grinders. It is also compatible with the IO-Link communication standard.
