The DSRT is the smallest strain sensor with the highest resolution (0.01 µÎµ) available on the market. It is offered with measuring ranges from 0..100 µÎµ up to 0..750 µÎµ (micro strain: µm/m).
The strain sensor is suitable for all static and dynamic applications and can be used wherever strains are expected, e. g. for process control in presses and punching machines, for monitoring blade deflection in wind energy plants, or for sheet metal forming applications in the packaging technology. The indirect force measurement enables the control and traceable documentation of forces in the process. It also guarantees the repeatability of the individual processes, thus ensuring consistent quality.
The DSRT is available with the measuring ranges Â±100, Â±250, Â±500, and Â±750 µÎµ. It has an integrated low-noise bridge amplifier with an analogue signal path and a high cut-off frequency (1 kHz). The available output signals are analogue current or voltage signals (4..20 mA, Â±10 VDC, mV/V) and a CANopen interface. The sensor offers high reliability, long-term stability, overload protection, and repeatability. The device conforms to protection class IP67.
Since the strain sensor is screwed on to the strain-stressed parts of the machine, it offers many advantages compared to glued strain gauges (SG): it is reusable, can be mounted much faster and easier, is replaceable without recalibration, and offers very high application security. Low mechanical setting and warming up enable a fast start-up. Compared to force sensors, the DSRT allows cost-efficient measurement especially of high forces. The device is 80 mm long, 26 mm wide, and 17 mm high.
