X-COEUS Macro/Micro Pressure Switches

Developed for the Automotive industry, COUES Intelliplastic®-based sensor technology offers customers a unique new low cost and incredibly rugged solution to provide two-state (“ON”/”OFF”) monitoring of direct pressure loading or other applied force conditions. With a time constant of a few microseconds, these devices provide near-instantaneous detection of an overpressure event.

The elimination of all acquisition and process electronics requirements has enabled QorTek to develop and now offer custom X-COEUS pressure sensitive ‘on/off’ switches that range from macro to micro footprint.

X-COEUS ‘on/off’ switches directly convert pressure into “ON” state or “OFF” state eliminating process electronics as to provide, in many cases substantial, risk reduction and increased reliability.

Available in a wide range of very low profile formats that can be integrated into load paths to monitor (a customer pre-selected) pressure threshold ranging from a few psi to hundreds of psi with many tens of kpsi overload survivability. With a duration lifetime measured in decades, these devices provide an ideal low cost/high reliability solution for enabling install of ‘on/off’ or ‘interrupt’ switches.

Because COUES pressure selective switches conduct only at, or above, (pre-set) threshold pressure these devices normally passively monitor at zero power consumption costs.
