1. Overview
This chapter provides an overview of the main HSMT-Compact scanner components.
The contents of a standard case are shown in Figure 1-1 on page 13.
Figure 1‑1 Case contents
The main HSMT-Compact scanner components are the frame (with four wheels and
two handles), the probe holders, the water-couplant distribution system, and the
encoder (see Figure 1-2 on page 14).

Frame
The frame provides a base for up to four conventional ultrasonic probes or
phased array ultrasonic probes. It is supported at both ends by subassemblies that
hold the wheels and handles used to move the unit across the surface being
inspected. If necessary, the handles can be removed to reduce the height of the
scanner.
Magnetic wheels
The magnetic wheels help hold the unit against a ferromagnetic inspection
surface. The wheels are covered with a plastic layer for smooth motion during
inspection (see Figure 1-2 on page 14).
Chapter 1
Page 21
DMTA017-01EN, Rev. F, August 2016
WARNING
To avoid injury, use caution when handling the magnetic wheels; the magnetic pull of
the wheels is strong and could cause bodily harm—for example, a finger pinched
between two wheels, or between a wheel and a steel surface.
Probe holders
The probe holders are used to secure the probes. The probe-holder position is
adjustable. The probe holders are also spring-loaded to ensure a proper contact
between the probes and the surface to be inspected.
Wat e r manifold
Four tubes branch out from one main water-entry point to supply the wedges
with water couplant.
Encoder
A wheel encoder measures the scanner displacement to determine the position on
the scan axis.
The encoder is waterproof and compatible with the OmniScan unit. The encoder
is also spring-loaded to ensure that it remains in contact with the inspection
surface, with adequate pressure for different pipe diameters.
Safety attachment ring
This ring can be used to secure the scanner with a safety hook (see Figure 1-3 on
page 16). If the scanner is equipped with an umbilical cable, this cable can be
attached to the ring to prevent overtensioning of the probe cables.
Umbilical bracket
An umbilical bracket is supplied with the scanner for quick attachment of a cable
bundle wrapped with a divisible shell (see “Attaching the Umbilical Cable” on
page 23).

Positioning a probe holder
Two removable rulers are provided on the top of the scanner frame to help
accurately position a probe holder. The edges of the probe-holder brackets can be
used to position the exit points of the ST1 and ST2 TOFD wedges, which are
designed to align with each other (see Figure 1-4 on page 17).

Alternative frame configuration
The frame can hold both conventional ultrasonic probes and phased array
ultrasonic probes.
The frame section between the wheels can be changed to vary the scanner length
(see Figure 1-5 on page 17).

Preamplifier (optional)
Sliding the wheel assembly to change the frame
configuration
When loosened, the wheel assembly slides freely on the frame, and can be
temporarily removed and reinstalled in a different configuration. For example,
the frame can be positioned to extend outside the limits of the wheels, which is
well-suited to hard-to-reach areas, such as pipe-to-component welds (see
Figure 1-6 on page 18).
Preamplifier
If necessary, a preamplifier (often required for TOFD inspections) can be mounted
on the frame. In the example shown in Figure 1-6 on page 18, an Olympus
TRPP 5810 pulser/preamplifier is used. A bracket is required to mount the
TRPP 5810 on HSMT scanners. This bracket is included with some TRPP 5810
packages, and can also be ordered separately (part number: HSMT-A-BRK5810
[U8779088]).

2. Scanner Assembly and Setup
This chapter explains how to adjust parts on the HSMT-Compact scanner (for
example, the wheel-assembly position on the frame), and how to set up the scanner
for inspection.
2.1 Changing the Frame Configuration
The frame configuration can be changed as follows:
• The frame section between the wheels can be changed to increase or decrease the
distance between the wheels. This is accomplished using frame sections of
different lengths.
OR
• The wheel-assembly position can be adjusted on the frame; it can be loosened and
moved along the frame section. As such, the wheel assembly can be temporarily
removed, and then reinstalled so that the frame and the probe extend outside the
limits of the wheels, which is ideal for hard-to-reach areas, such as pipe-tocomponent welds (see Figure 1-6 on page 18).
To change the frame section between the wheels
1. On the end of the scanner displaying the company name, perform the following
steps:
a) Using a hexagonal key, remove the two screws that attach the frame section to
the wheel assembly (see Figure 2-1 on page 20).
b) Remove the wheel assembly from the frame.
c) To facilitate reassembly, remove the T-nut, and then install it onto the new
frame section.

3. Operating the Scanner
The HSMT-Compact scanner is designed for manual use, and is straightforward to
operate.
To operate the scanner
1. Hold the scanner above the inspection surface, and then align the scanner so that
the inspection area is centered between the probes.
2. With the inspection area centered between the probes, bring the scanner’s
magnetic wheels into contact with the inspection surface.
3. Next, push or pull the scanner in the desired inspection direction.
If the inspection surface is made of a ferromagnetic material, the scanner does not
need to be pushed down to prevent liftoff.

4. Maintenance
This chapter contains procedures for replacing wheels, probes, and wedges for both
conventional ultrasonic and phased array ultrasonic technologies. The probes may
need to be replaced if they malfunction, or if the inspection application has changed.
Depending on operating conditions, the HSMT-Compact scanner parts might need
periodic cleaning.
4.1 Replacing Wheels
This section contains the procedure for changing the wheels once they are too worn.
To replace wheels
To avoid injury, use caution when handling the magnetic wheels; the magnetic pull of
the wheels is strong and could cause bodily harm—for example, a finger pinched
between two wheels, or between a wheel and a steel surface.
1. Using a flathead screwdriver, remove the screw that secures the wheel to the
frame (see Figure 4-1 on page 30).
Maintenance 29
Page 36

9. Install the new probe.
Before installing the new probe into the probe holder, ensure that there is enough
couplant between the probe and the wedge.
10. Tighten the probe inside the holder.
Do not overtighten the screws; doing so could crack the wedge.
11. Reinstall the yoke onto the holder.
12. Reinstall the yoke, probe holder, and probe assembly onto the spring-loaded arm.
This concludes the procedure for replacing a conventional ultrasonic probe.
4.3 Replacing a Phased Array Probe
This section describes the procedures for removing a phased array ultrasonic probe
from the scanner, and for removing the probe and wedge from the holder.
To replace a phased array probe
1. Turn off the couplant flow.
2. Disconnect the couplant tubes from the couplant source.
3. Disconnect the probe cable from the instrument.
To prevent any damage to the pins, always place the protective cover over the phased
array probe’s Hypertronics connector when it is disconnected.
4. Remove the scanner from the inspection surface.

5. Using a flathead screwdriver, remove the screw (at the back of the SLA) that
secures the yoke to the spring-loaded arm.
6. Remove the yoke, probe holder, and probe assembly from the scanner.
7. Using a hexagonal key, remove the screw (on the side of the yoke) that holds the
parts together (see Figure 4-5 on page 34).
Figure 4‑5 The screw that secures the yoke assembly
8. Using a cross-head screwdriver, loosen the four screws (see Figure 4-6 on
page 34), and then remove the probe from the wedge.

NOTE
CAUTION
Before installing the new probe into the probe holder, ensure that there is enough
couplant between the probe and the wedge.
10. Install and tighten the screws to secure the probe within the holder.
Do not overtighten the screws; doing so could crack the wedge.
11. Reinstall the yoke onto the holder.
12. Reinstall the yoke, probe holder, and probe assembly onto the spring-loaded arm.
This concludes the procedure for replacing a phased array probe.
4.4 Unit Cleaning
To clean the unit
The HSMT-Compact scanner’s external surfaces can be cleaned when needed.
The magnetic wheels can be strongly attracted to any ferromagnetic materials or
surfaces, which potentially can cause injuries (for example, pinched fingers) or
equipment damage.
1. Ensure the unit is turned off by removing the source of power.
2. Disconnect all cables.
3. To bring the unit back to its original finish, clean the housing with a soft cloth.
4. To remove persistent stains, use a damp cloth with a soft, soapy solution. Do not
use abrasive products or powerful solvents that could damage the finish.
Maintenance 35
Page 42
DMTA017-01EN, Rev. F, August 2016
5. Wait until the unit dries completely before reconnecting the cables.
