Product Notes
[1] Request Technical Note FTQ-STN5 regarding digital output signal.
[2] Extraneous load limits reflect the maximum axial load, lateral load, and bending moment that may be applied singularly without electrical or mechanical damage to the sensor.
[3] Where combined extraneous loads are applied, decrease loads proportionally.
[4] Root sum square of non-linearity, hysteresis, and non repeatability.
[5] Selectable High Pass cutoff frequencies of 5, 10, 20, 200 and 500 Hz.
[6] Selectable Low Pass cutoff frequencies of 10,000, 5000, 2500, 1200, 625 and 313 Hz.
[7] Bolt joint slip torque is calculated assuming a coefficient of friction (µ) of 0.1 and that grade 8 socket head cap screws are used and tightened to 75% of yield.
[8] Supplied with universal AC power adaptor.
