The ScanIR3 thermal scanner is designed for a wide variety of noncontact temperature measurement applications, including those in harsh industrial environments. Its robust housing incorporates standard water-cooling and air purge and 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 and thermal imaging system 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.

Key Features:

  • Thermal scanner temperature range: 20 to 1200°C (68 to 2192°F)
  • Operating ambient temperatures without cooling: 5 to 50ºC (32 to 122ºF) and with integral water-cooling: 180ºC (356ºF) maximum
  • Operating ambient temperatures with optional internal heater: -40ºC (-40ºF) minimum
  • Fast scan speed up to 150 lines per second
  • High optical resolution up to 200:1
  • PC independent input/output capabilities
  • Reliable Ethernet Communication
  • Rugged, waterproof housing with built-in laser
  • Built-in air purge and water cooling as standard
  • Field-replaceable window
  • One bundled sensing head cable with one-click connector to the scanner

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.

Key Features:

  • View two-dimensional thermal images, temperature profiles and differential images
  • Define product-specific configurations
  • Analyze temperatures automatically (Minimum, Maximum and Average)
  • Fail-safe alarm logging
  • Define a reference image display
  • Playback stored thermal images as a movie
  • System interfaces include analog/digital output modules, OPC or DDE server, or a serial COM port
  • Supports multiple ScanIR3 linescanners
  • Specify security passwords and access levels
  • Multiple language support

Adjustable Mounting Base

The Adjustable Mounting Base allows you to make small adjustments to where your linescanner is pointed, allowing you to gather more data from different parts of your process.

ScanIR3 High Temperature Enclosure

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.

Fiber Optic / RJ45 Ethernet Converter

The Fiber Optic / RJ45 Ethernet Converter S3X-LWL (type Advantech EKI-2541M) assures high reliability and stability in harsh environments, making it a robust bridge between enterprise fiberoptic backbones and Ethernet devices, like the ScanIR3 linescanner. Using fiber optics, you prevent electrical interference from corrupting the linescanner system.
