Resistive strain sensing for dynamic torque, rotational-speed and mechanical-power measurement.

Output-signal alternatives

Signal typeConfiguration alternatives
Frequency reference5–15 kHz
Current0–20 mA / 4–20 mA
Voltage0–5 V / 0–10 V / 1–5 V / ±5 V / ±10 V
Shaft and base side and end drawing references using the D D1 A B C C1 E E2 F G H H1 L dimension symbols

Shaft, key and mounting dimensions

ØD identifies the shaft and ØD1 the cylindrical body. ØA and B locate the base mounting holes; the remaining symbols identify dimensions in the two views. Key entries give width b × height h × length l × quantity n. Dimensional units require confirmation. Confirm the shaft, key and mounting dimensions for your selected torque capacity before specifying couplings and supports.
