Strain Ring with Quick Mount Latch DSRC QM Features • Installation without surface preparation • Simple and fast installations thanks to a quick mount latch • For tension and compression measurement • Ideal for restricted space conditions • For cyclical applications only Electrical Data Strain Gage Data Strain gage type Foil gages Bridge resistance at 24 °C 350 Ω 2 x quarter bridge Sensitivity at 24 °C Gage factor K= 2.00 ±0,5% (compensated with resistors) Temp. compensation Steel Transverse sensitivity nominal +0,7% Bridge circuit 2 x 1/4 bridge (see electrical connections) 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 Mechanical Data Connection 6 pin female (bayonet quick con.)

Recommended Environmental Conditions Surface installation spot Ra 3.2 (N8) or better Operating temp. range -10...+60 °C Storage temperature -40...+100 °C Protection class IP 54 3.12 Signal polarity < ±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 amplifiersand display boxes are equipped with a reset function to tare this offset. The bridge should be reset before each measuring cycle. 9 VDC 5 VDC The signal polarity depends on the bridge circuit. In combination with Baumer amplifiers, the polarity is positive under tensile load.
