Customized strain sensor tare capabilities for any application

Dynamic applications describe recurring, rapid cycles of force. In cyclic applications, it is important that the zero point is tared at regular intervals to prevent drifting of the measurement signal due to temperature differences. For zero adjustment in cyclic applications we offer two different taring options. Both have a reset or tare control input on the sensor, which can be used to trigger the zero point adjustment conveniently via the controller. Since the zero point adjustment in dynamic applications takes place periodically during the zero point run of a machine, we refer to this as process tare. The process tare can be triggered via the control system using a sensor input. If the reset or tare control input is pulled to >10 V or <3 V, depending on the logic, the sensor signal is set to zero and the zero point adjustment has been performed. Zero adjustment on these strain sensors is accomplished by a digital zero adjustment mechanism in which the zero correction is permanently stored during operation. Thus, a non-volatile, stable process tare is available independent of cycle times. The time span between the individual taring processes can be freely selected. It should be noted, however, that the zero point must be taught in again in the event of a power interruption. This zero adjustment is suitable for all dynamic applications. They can be used universally in all applications that require a periodic zero reset.
