According to aspects of the embodiments, an apparatus and method is proposed to detect nip width by use of at least one piezoelectric (PZT) crystal embedded into a roll at both the inboard and outboard ends. A piezoelectric (PZT) crystal generates a charge when subjected to a load and when the load is released. The PZT generate signal is channeled to the ends of the roller such as with a brush contact to be processed and used within machine control. The duration measure from application and released of the load is indicative of the dwell time and the amplitude PZT generate signal is a function of the pressure. The time and amplitude of the PZT signal can be calibrated to correlate directly to nip width or pressure and tracked in machine control.

Embodiments relate to reducing offset error in sensor systems. In embodiments, the sensitivity and offset of a sensor depend differently on some parameter, e.g. voltage, such that operating the sensor at two different values of the parameter can cancel the offset error. Embodiments can have applicability to stress sensors, Hall plates, vertical Hall devices, magnetoresistive sensors and others.

Two fixing points on the detection ring are fixed to a supporting substrate, and two exertion points are connected to the force receiving ring via connection members. When force and moment are exerted on the force receiving ring, with the supporting substrate fixed, the detection ring undergoes elastic deformation. Capacitance elements or others are used to measure distances between measurement points and the fixed assistant body and distances between the measurement points and the supporting substrate. Elastic deformation of the detection ring is recognized for mode and magnitude, thereby detecting a direction and magnitude of force or moment which is exerted.
