Fluke Raytek® MP150 High-Speed Linear Scanning Infrared Thermometer

Overview

The Fluke Raytek® MP150 High-Speed Linear Scanning Infrared Thermometer is an industrial-grade online thermal imaging system engineered for continuous, non-contact temperature profiling of moving targets in demanding manufacturing and process environments. Unlike conventional spot pyrometers or area-based thermal cameras, the MP150 employs a precision rotating optical assembly to perform rapid line-scan acquisition—capturing up to 1024 discrete infrared radiometric measurements across a single linear field of view (FOV) spanning up to 90°. Each scan line is processed in real time by an embedded high-speed microprocessor, delivering calibrated temperature values with microsecond-level temporal resolution. The system operates on the principle of narrow-band infrared radiometry, utilizing selectable spectral response windows (e.g., 1.0 µm for high-temperature metals, 3.9 µm for glass or flame monitoring, or 5.0 µm for plastics and coatings) to minimize emissivity-related error and mitigate interference from ambient radiation, steam, or combustion byproducts. Designed for integration into continuous production lines—including steel rolling mills, glass float lines, semiconductor wafer conveyors, and polymer extrusion systems—the MP150 delivers deterministic thermal data synchronized with motion control signals and PLC timestamps.

Key Features

• Real-time linear thermal profiling at up to 150 scan lines per second, enabling dynamic thermal mapping of fast-moving objects (e.g., hot strip steel at >20 m/s).
• Configurable spatial resolution: up to 1024 measurement points per scan line, with optical resolution ratios up to 200:1 for precise targeting of narrow features (e.g., weld seams, edge defects, or thin filaments).
• Integrated visible red aiming laser for rapid mechanical alignment and verification of measurement geometry without interrupting process operation.
• Dual cooling architecture: air-cooled standard configuration; optional water-cooled housing rated for ambient temperatures up to 85 °C and enclosure IP65 protection.
• Three isolated, user-configurable 4–20 mA analog outputs supporting HART protocol for direct connection to DCS, PLC, or SCADA systems without external signal conditioning.
• Built-in Ethernet TCP/IP interface compliant with IEEE 802.3, supporting Modbus TCP, HTTP API, and raw UDP data streaming for seamless integration into Industry 4.0 architectures.
• Field-upgradable firmware and support for optional digital I/O modules (e.g., TTL trigger input, alarm relay output, encoder synchronization).

Sample Compatibility & Compliance

The MP150 is optimized for non-contact temperature measurement of conductive and non-conductive materials in motion—including molten metal surfaces, annealed glass substrates, sintered ceramics, extruded polymers, and coated web materials. Its spectral band selection enables accurate measurement across diverse emissivity profiles (ε = 0.1–0.95), with factory calibration traceable to NIST standards. The instrument complies with IEC 61326-1 (EMC for industrial environments), IEC 61000-6-2/-6-4, and UL 61010-1 for electrical safety. When deployed with Fluke’s DataTemp® DP software, the system supports audit-ready data logging aligned with FDA 21 CFR Part 11 requirements—including electronic signatures, user access controls, and immutable change history—making it suitable for regulated industries such as pharmaceutical packaging line monitoring or aerospace composite curing validation.

Software & Data Management

The MP150 operates natively with Fluke DataTemp® DP—a Windows-based industrial software platform that provides real-time thermal line visualization, statistical process monitoring (SPC), and automated defect detection via user-defined thermal thresholds. The software includes an integrated OPC UA server compliant with OPC Foundation specifications, enabling bidirectional data exchange with Siemens SIMATIC, Rockwell FactoryTalk, or Honeywell Experion DCS platforms. Raw temperature arrays (1024 × N lines) are timestamped with microsecond precision and stored in HDF5 or CSV formats for post-process analysis in MATLAB, Python (NumPy/Pandas), or statistical quality tools. Configuration parameters—including emissivity tables, linearization curves, and alarm logic—are stored in non-volatile memory and can be backed up/restored via secure FTP or USB mass storage.

Applications

• Hot-rolling mill exit temperature profiling for flat-rolled steel, ensuring compliance with ASTM A6/A6M and ISO 4948 metallurgical specifications.
• Continuous glass ribbon temperature uniformity monitoring during float process, supporting ISO 10218 and EN 574 safety-critical thermal control loops.
• Real-time thermal signature acquisition for lithium-ion battery electrode drying ovens, aligning with UL 1642 and IEC 62133 thermal runaway prevention protocols.
• In-line temperature verification of 3D-printed metal parts during powder bed fusion (PBF), supporting ASTM F3184 material qualification workflows.
• Web temperature control in gravure printing or laminating lines, where localized overheating compromises adhesive bond integrity per ISO 8510-2.

FAQ

What spectral bands are available for the MP150, and how do I select the optimal one?
The MP150 offers interchangeable spectral filters ranging from 1.0 µm (for metals >600 °C) to 5.0 µm (for organics, paints, and low-emissivity surfaces). Selection depends on target temperature, emissivity, and atmospheric transmission—detailed guidance is provided in Raytek Application Note AN-112.
Can the MP150 synchronize with encoder or PLC pulse signals?
Yes—via optional digital input module, the scanner accepts quadrature encoder signals or TTL pulses to trigger line acquisition at fixed spatial intervals, enabling pixel-per-mm thermal mapping independent of conveyor speed variation.
Is the MP150 compatible with existing plant historians such as OSIsoft PI or AspenTech IP.21?
Yes—through its native OPC UA server or Modbus TCP interface, the MP150 publishes real-time temperature vectors directly to enterprise historian systems without middleware.
Does the system support multi-camera thermal stitching or cross-calibration?
While the MP150 itself is a single-line imager, Fluke’s DataTemp® DP software supports synchronized data ingestion from multiple MP150 units mounted orthogonally or axially, enabling synthetic 2D thermal reconstruction when combined with known geometric constraints.
What maintenance intervals are recommended for long-term operational reliability?
Optical path inspection and laser alignment verification are recommended every 6 months in harsh environments; cooling system filters require quarterly cleaning; firmware updates are issued biannually and validated per IEC 62443-3-3 cybersecurity guidelines.
