Notes
(1)
Dependent on amplier
(2)
Dependent on amplier. Under constant operating conditions. Self-heating of the forcer will cause expansion
in the thrust rod during the initial warm up period. In high duty applications (corresponding to an internal forcer
temperature of 80
o
C) a 1 metre thrust rod will expand typically by 250 µm.
(3)
Maximum error over 1 metre under constant operating conditions.
