When powered-up, the
PosiTector
automatically
determines which probe is attached and does a self-
check.
To disconnect a probe from a body, slide the plastic
probe connector horizontally (in the direction of the
arrow) away from the body. Reverse these steps to
attach a different probe. It is not necessary to power-
down the Gage when switching probes.
The
PosiTector
gage body accepts a wide variety of probe types
including magnetic, eddy-current and ultrasonic coating thickness,
surface profile, environmental, hardness, salt contamination and
ultrasonic wall thickness probes. See www.defelsko.com/probes
Press-O-Film Replica Tape
Press-O-Film provides a simple way to obtain an impression of a
surface for analysis. It consists of a layer of crushable plastic micro
foam affixed to a 50.8 µm (2 mils) incompressible polyester film. When
compressed against a surface, the foam collapses and acquires an
accurate impression, or reverse replica, of the surface.
Several grades of replica tape are available:
Tape Grade
H Range
2D/3D Range
Order Code
Coarse (C)
20 to 64 µm
0.8 to 2.5 mils
----------
R-PRESS
X-Coarse (XC)
40 to 115 µm
1.5 to 4.5 mils
----------
R-PRESSX
Optical Grade
Coarse (C)
20 to 64 µm
0.8 to 2.5 mils
----------
R-PRESSOG
Optical Grade
X-Coarse (XC)
40 to 115 µm
1.5 to 4.5 mils
10 to 115 µm
0.4 to 4.5 mils R-PRESSXOG
If only the maximum peak-to-valley height is needed, then
conventional Coarse or X-Coarse can be used. Placing the
compressed tape (replica) into the
PosiTector
RTR 3D
gives a
measure of the average maximum peak-to-valley height (H) of the
surface roughness profile. The Gage automatically subtracts the
thickness of the polyester substrate from all measurements. Press-
O-Film is available in Coarse (C) and X-Coarse (XC) grades to
accommodate measurements in different profile ranges.
