The Wheel Profile Measurement System uses multiple lasers and multiple high speed digital cameras embedded under the track to capture a profile of every wheel that passes over it. IEM supplies a complete line of automated wheel inspection stations ranging
from slow speed shop systems to high speed mainline applications. Customers are using WPMS data in yard applications to route cars with defective wheels to trouble tracks, locomotive applications to conduct wheel diameter measurement comparisons,
and in transit applications to track wheel wear and do predictive, condition-based maintenance.
Product Overview
Laser Projection Measurement: The WPMS-1800 uses dual-sided multi-line lasers and high-speed digital cameras embedded under the track to capture a profile of every wheel that passes over it.
Highly Accurate: WPMS-1800 takes up to three separate measurements simultaneously, providing the most accurate wheel profile measurement possible.
High-Speed & Heavy Freight: The Model 1800 is housed inside a temperature controlled, structurally heated steel chassis called an Instrumented Tie Box.
Easy Installation: As a prefabricated unit, the ITB minimizes installation time and cost; the major construction component of the installation is as simple as replacing a tie or sleeper.

Key Features & Details
IEM’s WPMS-1800 utilizes redundancy in the design and assembly of multiple lasers and cameras to provide our patented “True-Vision” 3D Optical Metrology for calculating the wheel measurement parameters. For each wheel, capability to
measure or detect includes time/ date, axle number, train speed, wheel 2D profile, wheel diameter, flange height, flange width, flange angle, rim thickness, hollow tread, tread buildup, and rim rollover.

Additional Benefits/Factors
Shipped with the Instrumented Tie Box is an assortment of attachments which transform the ITB from a simple steel “Sleeper” to the core structure of a rugged measurement system. These attachments include equipment enclosures for the measurement
devices, as well as environmental conditioning units like blower and exhaust units. There is even an attachment that provides protection from dragging equipment.

Product Overview
Efficient & Effective: The WPMS-1600 works by capturing multiple images of the front and back profiles of each wheel.
Highest Resolution: IEM’s line of WPMS products have the highest resolution of any profile system on the market today, with measurement repeatability in the 0.1mm range.
Defect Detection: The high-resolution cameras display every variation around the circumference of the wheel as a result of normal wear.
Custom Measurement Reports: Once the basic profile has been captured, any number of standard or custom measurements can be generated, including flange thickness, flange height, flange angle, rim
thickness, back-to-back, and wheel diameter.

Product Overview
High Percentage Detection: WPMS-1400 has a high percent detection rate, meaning flats touching the rail will be detected.
In-Shop System: Sensors are designed to respond only to mechanical impacts, so there is a very low false alarm rate.
Weather-Proof: The system will be unaffected by natural variables or possible electrical interference.
Fastest to Install: The WPMS-1400 is quick and easy to install, as well as fully customizable, and measures all wheel sizes and types ranging from large locomotive wheels to smaller vehicles. P
