The UV PowerMAP measures UV irradiance, radiant energy density and temperature. The UV PowerMAP simultaneously provides information for four spectral regions (EIT UVA, UVB, UVC, and UVV).
EIT's UV PowerMAP is an advanced profiling system that measures temperature information derived from their optics and thermocouple probes in UV curing processes. The information is transferred to a PC where it is presented in a graph and data format for viewing, analysis manipulation and comparison. The information is characteristic of the same energy and irradiance that would be impinged on an actual work piece passing through the curing process.
Features:
- User adjustable sampling rates from 128 to 2048 samples/second. The faster sample rates ensure high resolution and repeatability even at higher process speeds.
- Easy to use PowerView™ software program that displays collected data in graphical and tubular forms. The PowerView™ software allows the user to also compare two different files.
- Detachable Optics Head that allows the use of different optics heads with a single Data Collection Unit- (UDC). This feature minimizes downtime during re-calibration and allows a single UDC to use low and high power optics heads.
- Collection and storage of up to one million data points for accurate UV and temperature mapping in your system.
- Offset optics allow easy measurement at conveyor edge
- Type J thermocouple records temperatures from 0-500 degrees Celsius
- Low, narrow profile to allow access to most curing applications
- Rugged aluminum chassis and stainless steel case
- Provides user selectable instrument default modes for data analysis and comparison, screen, and operational settings.
Applications:
- Document, measure and maintain the performance of an individual UV System or entire manufacturing line from start to finish.
- Document, measure, confirm, and maintain the spatial geometry and original design specifications of your UV System. Easily evaluate lap-bulb configuration and focus, reflector shape and focus reflector efficiency.
- Compare reflector materials and shapes, wavelength-specific degradation, and uniformity of one or more UV lamps.
- Easily identify the type of bulb in the system. Compare spectral output, degradation, and uniformity of one or more UV lamps.
- Measure and document substrate temperatures during the cure process to prevent damage to temperature-sensitive materials.
- Track and store data for statistical quality control regulation compliance or historical comparisons.
- Print run data to attach to work orders, reports, or quality audits.
- Archive measurement data to track system performance over time.
PowerView™:
The PowerView™ is a windows based LabView program written at EIT to work with the UV PowerMAP. PowerView™ has evolved as the Windows platform has changed.
The data collected with the radiometers is transferred through the serial port of the computer to the PowerView™ program. The data is available for viewing on the computer screen. Included with the data is information on the collection instruments as well as a time/date stamp. The user can ass several lines of information to the PowerView™ file. This allows process, equipment and formulation variables to be stored with the file which is especially useful when running trials or doing R&D work. The information collected can be saved and accessed later for comparison to another file. The date and files can be analyzed, manipulated, customized, printed, emailed and even exported into a spreadsheet program if needed.
The PowerView™ shows the status of a curing system in a clear, easy to read format. The user can see which lamps and reflectors in a system are well focused and performing most efficiently. PowerView's™ ability to compare two different runs is one of its most important features. The run data files are referred to as a "sample" file and a "reference" file.
Variables such as reflector materials, reflector shapes, wavelength-specific reflector degradation and uniformity, and lamp focus can be documented. Companies using multi-lamp curing systems and those that are using different spectral lamps within a system will find these radiometers indispensable.

Unit Operation:
A Type J thermocouple probe is used for substrate temperature measurement. Temperatures from 0 degrees to 500 degrees Celsius are recorded at 32 samples per second. This is an important function if curing is taking place on temperature sensitive substrates.
The UV PowerMAP is powered by nickel hydride (NiNH) batteries, which can be recharged approximately 500 times before needing replacement. An audible alarm sounds when the batteries need recharging.
Routine maintenance for the units consists of battery charging, cleaning, and returning the optics head for routine calibration. Recharging is accomplished by one-hour "quick" charge. Keeping the optics clean is essential for getting proper measurement results, and it requires only cotton swabs and acetone. The case can be cleaned with isopropyl alcohol and a soft cloth.
Since the optics head disconnects from the DCU, only the optics head has to be returned for periodic calibration. It is connected to the collection unit by two mechanical pins and a row of electrical contact, and locked into place by two setscrews. Another optics head may be purchased to avoid down time during recalibration.
EIT UV PowerMAP Users Manual (PDF)
Five areas where the PowerMAP System Excels:
- Multi-lamp UV System- run the instrument through one time and:
- View each lamp individually instead of turning lamp on and off one at a time to get readings
- Confirm and check the type of bulb in each UV station when using additive bulbs
- Comparisons made over time and between different
equipment systems
- Improving communication internally within a company and between suppliers, vendors, and end users - in Graph View screen, comparing a sample and reference file sent electronically is worth a thousand typed email words when trying to explain system changes or performance
- At fast production speeds with an adjustable sample rate up to 2048 Hz
- Evaluating power supplies-the-fast sample rate allows you to check for repeatability, uniformity and performance.
Summary:
The UV PowerMAP has an enormous advantage over other UV measurement instruments on the market. It allows the user to evaluate the entire lamp system to see how well it delivers UV light to the actual cure surface.
The collected data allows the user to adjust the curing process to ensure that the UV System is operating at maximum efficiency. The data that is graphed can be archived for future reference or printed and attached to work orders for ISO or FDA compliance.
