Line scanning accessory for spot pyrometers
09 December 2015
Fluke Process Instruments has introduced the SpotScanTM line scanning accessory for its family of spot pyrometers. Compatible with Endurance, Marathon, and Modline 5 and Modline 7 Series of infrared (IR) noncontact temperature measurement sensors, the accessory features a special scanning mechanism that enables users to gather temperature data over a larger area on the target.
The SpotScan line scanning accessory helps optimise the performance of IR thermometers in applications ranging from metals processing and induction heating, to carbon graphite production. It is especially well-suited for web and conveyor hot spot or cold spot monitoring.
With the SpotScan accessory, industrial facilities can continue to use the advanced optics of their Fluke Process Instruments IR temperature sensors to achieve small spot sizes on the measurement target, but also 'spot sweep' over the target to see a larger area—thus obtaining additional information on critical production processes. Users can see a hot spot over a larger area and continuously monitor the analog output for temperature variations that exceed defined limits.
The SpotScan accessory allows plant operators to employ signal conditioning sensor capabilities to obtain temperature information in a variety of different ways. For example, use of the 'peak picker' function helps identify hot spots over a larger area. The averaging/response time functions provide average temperature over an extended range. In either case, operators benefit from an expanded view and increased awareness of process conditions.
The SpotScan accessory is available with options for sighting the IR instrument and periodically checking sighting accuracy. Onboard controls make it easy to manipulate the end or center positions of the scan, as well as its frequency. For a sensor equipped with a laser, the user can simply turn the unit on to see exactly where the sensor is aimed. For units equipped with through-the-lens sighting, scanning at the end points can be stopped to make necessary aiming adjustments.
The SpotScan line scanning accessory uses the existing sensor DC power supply. Its durable IP65 enclosure is designed to withstand ambient temperatures up to 60°C (140oF), and an air purge option is available for use in dusty or dirty environments.
