2.2 . Load measuring

Load measur1ng is effected by a pendulum gauge. The oil pressure

3r1s1ng ln the working cylinder is transmitted through ~he

measuring line to the measuring piston, . 'fhich is 1 pped-1n ln

the measuring cylinder. To guarantee the high measuring

prec ision the mea sur ing p iston is cont inuously moved "oy :3~.sma 11_.

2.5. Safety equipment

Electric contacts for limitlng the minimum and maximum load

ar fitted on the load pointer (8), which with switched-on machine are continuously under tension. After the preparations

for each test are finished, these ~lectric contacts must be

set on the required testing load limits and after the test s

f1n1shed, they must be returned into the zero position, to

guar~ntee free switching-on of the machine of the following

tes ts. ~ . . .

The electric contacts on the pendulum gauge and the iimit switch

on the pendulum weight rod form the internal safety circcrit o (.

the testing plant . If the safety equipment is ready for

operation the c ontrol lamp (35 ) shows continuously . If tQe safety circuit is interrupted, 1.e. if an electric cont.ac.t.,

rests on the l~ad ~c i n ter, the control lamp does not show anct

t he plant cannot be switched on.

A second safety circuit is the external snfety circuit, the

control lamp (36 or 36a) shows that it is ready for operation. To this external safety circuit all safety equ1pment is connest~et

~hich exist on parts of the plant outside of the control panel ..
