Line scanning accessory for spot pyrometers

23 November 2015

Fluke Process Instruments has introduced the SpotScan line scanning accessory for its spot pyrometer range. 

Compatible with the Endurance, Marathon, and Modline 5 and Modline 7 Series of infrared (IR) noncontact temperature measurement sensors, the scanning accessory includes a scanning mechanism which 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 utilise 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, obtaining additional information on critical production processes. Users can see a hot spot over a larger area and continuously monitor the analogue output for temperature variations that exceed defined limits.

It enables 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 are said to 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 is able to 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 accessory makes use of the existing sensor DC power supply and is designed to withstand ambient temperatures up to 60°C, with an air purge option available for use in dusty or dirty environments.
