Product Description

The ScanIR®3 linescanner and thermal imaging system is designed for a wide varierty of noncontact temperature measurement applications, including those in harsh industrial environments. Its robust housing incorporates standard water-cooling and air purge, and also features built-in laser sighting. A rugged processor box provides universal input and output (I/O) capabilities in the field without the need for an external computer.

The ScanIR3 linescanner has one of the fastest scan speeds in the industry and offers complete data about even the highest-speed manufacturing processes. Unlike point sensors that measure a single point, the linescanner measures multiple temperature points across a scan line. Its motorized mirror scans at rates up to 150 lines per second, allowing rapid detection of temperature non-uniformities and hot spots. Rotating optics collect infrared radiation at 1024 points within a 90-degree field of view, and industry-leading optical resolution (up to 200:1) enables detection of smaller temperature anomalies.

The ScanIR3 system is exceptionally easy to deploy and manage: a single bundled sensing head cable with a one-click connector to the scanner allows for fast and trouble-free installation. The unit’s processor box supports various industry interfaces, including Ethernet, fiber optics (optional), and analog/digital I/O.

Designed for reliability and continuous operation, this advanced infrared linescanner provides accurate, real-time thermal imaging and additional features, including:

  • Reliable brushless scanning motor
  • Field-replaceable window

ScanView™ Pro Software

Real-time thermal imaging is provided by ScanView™ Pro software for temperature monitoring, display and analysis. With ScanView Pro software, you can quickly detect a hot spot or non-uniformity before it becomes a problem. The multifunctional ScanView Pro software allows custom configuration of ScanIR3 operating parameters, and display of thermal images and temperature profiles on a standard personal computer (PC).

The software includes features to subdivide thermal images from the ScanIR3 linescanner into portions of specific interest. Temperatures in each portion can be processed for a certain math function, such as average, maximum, or minimum temperature. In case of a thermal defect, a fail-safe alarm is triggered and logged.

Operating Ambient Temperatures
  • without cooling: 5 to 50ºC (32 to 122ºF)
  • with integral water-cooling: 180ºC (356ºF) maximum
  • with internal heater (optional): -40ºC (-40ºF) minimum


The ScanIR3 linescanner is offered with an optional modular, high-temperature enclosure system specifically designed to protect the scanner from exposure to process temperatures up to 1090°C (1994°F). While protected in this enclosure, the linescanner can operate comfortably in high-temperature processes, such as those seen in manufacturing steel and other metals, as well as glass and a variety of minerals.

A full list of accessories, as well as specifications and product dimensions are available in the ScanIR3 linescanner product brochure.
