PCT No. PCT/US80/00291 Sec. 371 Date: Mar. 18, 1980 Sec. 102e Date: Mar. 18, 1980 PCT Filed: Mar. 18, 1980 Pub. No. WO81/02710 Pub. Date: Oct. 1, 1981. Apparatus (19) for sensing forces (29) such as in a power transmission apparatus (10) and magnifying the sensed forces suitably to provide an output (28) such as for use in controlling associated equipment (12, 18) to limit the forces. The sensing apparatus (19) includes a flexible beam (30) having a first portion (34) which is fixedly retained as to a fixed portion (23, 24) of the wall member defining the deflectible portion (22). Beam (30) further includes a second portion (33) which is connected to a deflectible wall portion (22) of the wall member (21) which is deflected as a function of force transmission through the apparatus. The flexible beam (30) is provided with a distal arm (31) which is swung by the deflection of the beam to provide an output signal (28) at the distal end (32) of the arm so as to provide a preselected magnification of the deflection of the deflectible wall portion (22). A stabilizer (57 ) is provided for stabilizing movement of the arm (31) by the deflectible beam (30).
