Bolingbrook, IL, February 2001 A new stationary ultraviolet energy measuring device from IST America the North American subsidiary of IST Metz continuously measures and controls the output of ultraviolet energy on printing presses and converting equipment.  The system consists of a sensor and a monitor which continuously gauges and regulates UV energy output relative to press speed.  The IST UV-S3 Sensor measures absolute ultraviolet radiation intensity as great as 1500 mW/cm2.  Electrical interference is eliminated by screening the sensor, and by transferring the data digitally from the sensor to the processing unit.  The unique spectral sensitivity of the IST UV-S3 Sensor permits measuring energy in different ultraviolet ranges quickly and efficiently.  The sensor is cooled by compressed air. The IST M2.2 UV Monitor can accommodate one or two sensors, and is easily programmed.  Sensor internal temperatures and tolerances, including correcting factors, are automatically controlled.
