Equilibration devices are recommended for improving accuracy and lifespan of Tekscan systems. During equilibration, the sensor is inserted between a flat backing plate and an air filled bladder, which is inflated in order to apply a uniform pressure to the active area of the sensor. The equilibration process allows the software to compensate for any variation or uneven output across individual sensing elements caused by manufacturing or repeated used of the sensor. Equilibration devices are useful to perform quality assurance checks on the sensor and confirm uniform output by the sensor. 




Why Equilibration?

Over time and through repeated loading, individual force sensing elements will eventually start to vary somewhat in sensitivity. The equilibrator applies a uniform pressure across the face of the sensor, allowing the software to easily see and quanitfy these variations. A digital compensation factor is automatically created and applied to each individual sensng element. This normalizes all of the sensing elements on the sheet, improving the accuracy and extending the lifespan of the sensor.
