Fluke Alignment Laser FLUKE-831, Class 2

Fluke Alignment Laser, 0 to 360° Measurement Range, Class 2 Laser - FLUKE-831

This alignment laser is a portable shaft-alignment instrument designed for precision adjustment of coupled rotating machinery in industrial settings. It employs a coaxial reflected-laser measurement principle and a guided user Interface to Streamline alignment tasks, reducing wear on couplings, bearings and Seals while improving machine availability and product consistency.

Features & Benefits

• Measurement resolution 1 μm and 10 μrad angular for fine adjustments
  Levelling accuracy greater than 99% to ensure precise shaft co-planarity
  Rotational measurement range 0 to 360° for full-shaft analysis
  Single red laser diode with less than 1 mW beam power for extended reach
  Wireless transfer up to 30m for cloud-based data handling
  Battery runtime approx. 10 hours for full-shift portability

**Applications**

• Suitable for alignment of motor and pump couplings on plant machinery
  Ideal for maintenance teams performing thermal growth compensation
  Used for field verification after machine installation and repairs
  Can be used for condition-based maintenance workflows with trending
  Suitable for horizontal, angular and vertical shaft alignment tasks

How does it compensate for machine thermal growth during alignment?

The system includes a thermal growth calculator that factors dynamic machine movement into the correction values during adjustment.

What connectivity options enable data management on-site?

It supports Wi‑Fi for Cloud transfer and wireless communication for remote data exchange with PC software.

What environmental conditions can the sensor and reflector tolerate?

The sensor and reflector offer dust and water resistance with operational temperature ranges down to -20 °C and up to 60 °C for the reflector and -10 °C to 50 °C for the main unit.

What indicates laser and battery status during use?

LED indicators provide visible status for the laser beam and battery as well as for wireless communications.

Which accessories are supplied to facilitate field deployment?

The package includes sensor and reflector covers, mounting brackets with support posts, a carrying case, cabling and a USB drive for data handling.
