Strain Ring with Axial Cable Exit DSRC AX Features • Ideal for use with telemetry system • For tension and compression measurement • Installation without surface preparation • For cyclical applications only Electrical Data Strain Gage Data Measuring range ±1000 µε (1 µε = 0,001 mm/m resp. 1 µε equals 0,001 mm strain per meter of shaft) Output signal per 1000 µε 1 mV/V (with completed full bridge) Combined error Linearity Hysteresis < 1% FS < 0,5% FS < 0,5% FS Repeatability < 0,2% FS Zero, bridge balance < ±200% FS (depending on installation) Since the gages are pressed-on, the bridge can have any arbitrary zero offset after the ring is mounted. Baumer amplifiers and display boxes are equipped with a reset function to tare this offset. The bridge should be reset before each measuring cycle. Excitation max. Recommended 9 VDC 5 VDC Surface installation spot Ra 3.2 (N8) or better Signal polarity The signal polarity depends on the bridge circuit. In combination with Baumer amplifiers, the polarity is positive under tensile load.
