Marine Propeller Inspection Systems

The three components of a Prop Scan Inspection System

1

Prop Scan

Measuring Assembly

The Machine

Hardware

A Measuring Assembly is chosen to suit the range

of propeller diameters you wish to inspect.

 

We design, manufacture, and sell a large range

of Measuring Assemblies to suit any application.

 

There are two types Measuring Assemblies.

RT = Rotating Table   RB = Rotating Beam

Model types are explained below.

 

Note: There is a minimum diameter restriction with RB’s.

Prop Scan

Measuring Software

Prop Scan Measuring Software collects the measured data and sends the data to the Prop Scan Reporting Software.

 

There are two versions of Prop Scan Measuring.

Prop Scan MeasE4 = Standard Resolution

Prop Scan MeasQA = High Resolution (HR)

 

3

Prop Scan

Reporting Software

Prop Scan Reporting software receives the measured data, processes the data, then produces Assessment Reports and Quality Certificates along with reports used in the production, repair, correction, modification and optimization of propellers.

 

There are two versions of Prop Scan Reporting.

Prop Scan E4 = Standard Resolution

  Prop Scan QA = High Resolution (HR)

Prop Scan E4

Prop Scan E4 has built a reputation around the world as the most advanced recreational and commercial marine propeller inspection and repair system.

2

Prop Scan MeasE4

Prop Scan MeasE4 is the measuring software designed to collect data from the Prop Scan E4 Measuring Assembly and send the data to the Prop Scan E4 Reporting System software.

 

Note:

The following four Software packages are compatible with Prop Scan (HR) High Resolution Measuring Assemblies.

Prop Scan Measuring Assemblies  Hardware

Measuring Assemblies are available in two design configurations RT & RB

 

To measure with RT you take the propeller to the RT Prop Scan.

 

To measure with RB you take the RB Prop Scan to the propeller.

 

(HR) Indicates Measuring Assemblies are High Resolution Systems.

RT

The RT prefix indicates a Rotating Table Measuring Assembly. The Rotating Table sits on the floor and the bore of the front face of the propeller boss locates in the Rotating Table chuck and the propeller is rotated beneath the beam during measurement.

2

RB

The RB prefix indicates a Rotating Beam Measuring Assembly. The propeller sits on the floor and the RB locates in the bore of the rear face of the boss. The propeller is stationary and during measurement the beam rotates over the propeller. Please note there is a minimum diameter restriction with RB’s.
