EIT MicroCure

EIT’s MicroCure® measurement system is comprised of two separate stand-alone items; the data collection radiometer which is placed in the ultraviolet (UV) environment to be measured, and a DataReader which reads and displays the measurement results from the radiometer.

The UV integrating radiometer is a microprocessor-based, electro-optical instrument that measures and accumulates the total UV energy that is applied to the measurement surface of the instrument. The MicroCure® radiometer measures the total amount of UV energy that would be impinged on a work piece passing through the curing system and the peak UV irradiance. The radiometer combines very small physical size and adaptability to address a variety of demanding physical and thermal measurement environments.

Operation

MicroCure DataReader

The MicroCure® radiometer is designed to be placed in a UV curing environment so that the UV radiation strikes the radiometer in the same manner as 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 amount of UV energy 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 the total UV energy 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

Aplications

Benefits

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 provides measurements in such previously inaccessible areas as small conveyorized semiconductor marking, credit cards, small part curing, etc.
Small Container Curing UV environments encountered in small container curing such as cosmetic or drink containers, are generally characterized by putting the radiometer in the place of one of the containers. In the case of cylindrical containers like shampoo bottles, the radiometer can be attached onto 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 DataReader displays the radiometer readings.
3-D Objects Attach the radiometer 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 to the web. 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 MicroCure® 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 MicroCure® radiometer’s very small size makes such measurements generally possible.
