  • Statistical Process Control measurements




Operation

The MicroCureTM radiometer is designed to be placed in a UV curing environment so that the UV radiation strikes the radiometer in the same manner it would strike an actual work piece. The radiometer is designed so that when UV strikes the measuring face of the instrument it automatically measures and stores electronically the UV energy density impinged upon it and the peak UV irradiance. Upon completion of the measurement the operator places the radiometer in a stand-alone DataReader. Depressing the "Select" button on the DataReader downloads the information in the radiometer and displays on an LCD display the total UV energy density and peak UV irradiance seen by the radiometer. A short push of the "Select" button toggles between the dosage and UV irradiance measurement readings. Pressing the "Reset" button on the DataReader will clear the electronic storage in the radiometer and the readings on the DataReader display. The radiometer is now ready to take another reading.

If no UV radiation above a threshold value is encountered for four minutes, the radiometer will enter a "deep sleep" mode. In the "sleep" mode the radiometer batteries will last a minimum of one year. Alternatively, the unit can make 200 measurements on the same battery.

To ensure that the radiometer battery has sufficient remaining energy, the DataReader display indicates how many readings have been made by the individual radiometer since new.

The DataReader is battery powered and can perform 36,000 readings on a single battery. A low battery condition is indicated on the display.

Applications

The MicroCureTM radiometer is very versatile because of its small size and automatic operation. Exact method of use will depend on the given application. Some specific examples are:

  • Small Conveyor or Batch Mode – In this application the radiometer is placed in the UV curing environment in the same manner as an actual work piece. The radiometer’s very small size and ability to withstand harsh environments provide measurements in such previously inaccessible areas as small conveyorized semiconductor marking, credit cards, small part curing, etc.

  • Small Containers Curing – UV environments encountered in small container curing such as cosmetic containers or drink containers, are generally characterized by putting the radiometer in place of one of the containers. In the case of cylindrical containers like shampoo bottles, the radiometer can be attached to the product using EIT's innovative Web Accessory Kit. The radiometer can also be placed inside a container with the measurement being made through a pre-cut hole. The radiometer is retrieved at the end of the process and inserted in the DataReader. The Data Reader displays the radiomenter readings.

  • 3-D Objects –Attach the radiomenter to objects such as furniture or vehicle dashboards to monitor UV levels on unusual shapes and processes.

  • Web Press – In this application the radiometer is attached and removed from the web using a special Web Accessory Kit. The measurement is made as the radiometer passes under the lamp station in question. (The radiometer is placed on the web while it is stationary or moving and removed prior to the print station). Because of its very small size, it can pass over rollers without damage.

  • Compact Disc Manufacture – The MicroCureTM radiometer is sufficiently small that it can be inserted directly into one of the CD "nests" to measure the UV radiation used to cure UV coatings and finishes.

  • Flexible Light Guide Curing Systems – Some flexible light guide systems, such as those used in curing adhesives on small objects, are fixed into geometries that make it impossible to place a standard radiometer in the curing region. The MicroCureTM radiometer's very small size makes such measurements generally possible.
