Motorized plunger actuation
The CT 2501, CT 6001, MT 60 M and
MT 101 M length gauges feature an integral
motor that moves the plunger. It is oper-
ated through the switch box either by push
button or over the connection for external
actuation. The plungers of the CT 2501,
CT 6001 and MT 60 M length gauges must
not be moved by hand if the switch box is
connected.
The gauging force of the CT 2501,
CT 6001, and MT 60 M motorized length
gauges is adjustable in three stages
through the switch box. The force remains
constant over the measuring range but
depends on the operating attitude.
Regardless of the operating attitude—
whether it measures vertically downward
(with the SG 101 V switch box) or
horizontally (with the SG 101 H switch
box)—the MT 101 M exercises a constant
gauging force.
External plunger actuation by coupling
For the CT 2502, CT 6002, MT 60 K,
MT 101 K and special versions (without
spring) of the MT 1200, MT 2500, and
ST 1288, the plunger is freely movable.
For position measurement, the plunger is
connected by a coupling with a moving
machine element. The force needed to
move the plunger is specified as the
required moving force. It depends on
the operating attitude.
