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.
