Torque Limiter Screw Assembly
The Silver Gate™ bridge and clamp anvil assembly ( 15 ) is provided
with a special built in torque limiter screw assembly ( 16 ). For solid
sampling, an appropriate anvil ( 13 ) is fitted to the clamp head pressure
pin ( 14 ). A solid sample is placed upon the ZnSe or Ge ATR crystal to
cover it completely and the bridge is closed and locked to the bridge
support block (
17 ).The bridge is locked shut by pushing down on the T
shaped black quick lock/release knob ( 18 ) and turning it a 90° angle
clockwise. (When the bridge is unlocked and open the T shaped
locking knob is parallel to the direction of the bridge – see Figure 13.)

With an appropriate anvil (
13 ) fitted, the torque limiter screw assembly
knob ( 16 ) is turned in a clockwise fashion to provide a pre-determined
set pressure (50lbs load spread over the anvil face) to the sample. In
operation the entire torque limiter screw assembly knob is rotated until
a sufficient load and hence pressure has been applied to the sample.
The torque limiter screw assembly knob (
16 ) will continue to rotate
when the set load is reached, but the black colored cover cap with the
white “cross” mark on top of the knob acts as the indicator when the set
applied load is reached in ceasing to rotate. (i.e. the white cross stops
rotating when the torque/load limit is reached.)
