Shaft Alignment System

Geometric Measurement System

AT-400

Dual Precision at Every Turn

Double down on misalignment with the Acoem AT-400, featuring robust dual axis sensors and unmatched versatility for virtually any shaft alignment scenario.

Acoem AT-400

The AT-400 Shaft Alignment System is a state-of-the-art solution for precision machinery alignment. With 2-axis PSD alignment sensors, dual sweep, and dual multipoint methods, it ensures accurate alignment over a 65 feet (20 meter) measuring distance. Featuring the user-friendly GuideU™ interface, cloud connectivity, and a lifetime warranty, the AT-400 is Acoem’s most comprehensive and user-centric alignment system.

DualXL PSD Detectors

The 20x20mm² M9 & S9 position-sensitive detectors simultaneously measure horizontal and vertical measurements and offer a high resolution of 0.001mm. The M9 & S9 are currently the thinnest 2-axis sensor on the market, are lightweight (.67lb), and feature a 20-meter (65 ft) measurement range. Thoughtfully designed sliding covers for the detectors and charging ports ensure the product stays protected when stored or not in use.

Dual Measurement

Our 2-axis sensors record measurements from both the moveable and stationary coupling side to supply the data within our alignment programs.

When we say

“Two is Better Than One”

we mean it.

DUAL SWEEP

With the Dual Sweep method, you can quickly and easily obtain readings with a single rotation of the shaft.

DUAL MULTIPOINT

The Dual Multipoint method enables you to record measurements from multiple points from any position on the rotation.

DUAL VIEW

The Dual View feature enables the real-time visualisation throughout the entire alignment process in both horizontal and vertical directions simultaneously.

GuideU™ Interface

GuideU™ is the next generation of 3D shaft alignment graphical user interface – our patented, customizable, icon-driven and color-coded display system that makes measuring, aligning, and reporting simple. Featuring realistic machine graphics and animated help screens, the risk of human error is minimized to take the guesswork out of shaft alignment.

Cloud Connectivity

Supplied with cloud connectivity, the AT-400 allows users to effortlessly upload alignment reports to Acoem’s proprietary web portal, ensuring seamless data management and easy access to alignment records for analysis and comparison. With just a tap of a button, technicians can send their alignment reports directly to the portal, streamlining their process of documentation.

Lifetime Warranty Benefit

The AT-400 comes with the added assurance of a lifetime warranty, providing customers with unmatched peace of mind and long-term reliability. This commitment to quality reflects Acoem’s confidence in the durability and performance of this cutting-edge alignment system.

Vertical Shaft Alignment

Determine and correct the relative position of two vertically/flange mounted machines that are connected, such as a motor and a pump, so that the rotational centers of the shafts are collinear.

Flatness

The flatness measurement program uses a laser plane as reference. The deviation in distance between the laser plane and the measurement object is measured in one or more positions using the Acoem T21 flatness sensor paired with the M9 sensor as the receiver.

This measurement method is similar to the classic Dual Sweep method, but with one key distinction: Data recording halts automatically when shaft rotation ceases.

The Dual Multipoint method enables measurement initiation from any position on the rotation, allowing recording of multiple points for optimized calculations. Ideal for uncoupled shafts, non-rotatable shafts, sleeve bearings or journal bearings.

Similar to the classic Multipoint method, this measurement method records automated measurements for greater convenience.

In the Tripoint method, the alignment condition can be calculated by recording three points while rotating the shaft at least 60°. In this method, all points are recorded manually by the user.

This method seamlessly incorporates the Tripoint approach, offering the added advantage of fully automated measurements throughout the process.

In the Clock method, machinery positions are calculated by taking three points with 180° of rotation.
