18 / 76 page  13 Photoconductive Cell Testing and General Notes Production Testing of Photocells - PerkinElmer’s New Approach Historically within this industry, vendors have set their production testers to the limits specified on the customer’s print. Measurement errors due to ambient temperature, calibration of light source, light history effect, plus any tester errors have always guaranteed that a certain percentage of the cells shipped are out of specification. This practice is incompatible with the realities of today’s marketplace, where quality levels are being measured in parts per million. With this new catalog, PerkinElmer is taking the opportunity to correct this situation. for parts in this catalog, PerkinElmer has pulled in the test limits on our production testers to compensate for measurement errors. General Notes (Refer to the following data specification pages.) Photocells are supplied categorized into groups by resistance. All groups must be purchased together and PerkinElmer maintains the right to determine the product mix among these groups. Dimension controlled at base of package. Photocells are tested at either 1 fc or 10 lux. 2 fc typical values shown in the tables are for reference only. Cells are light adapted at 30 - 50 fc. The photocell “grid” pattern can vary from that shown. PerkinElmer reserves the right to change mix grid patterns on any standard product. The resistance for any standard cell is controlled at only one light level. If the resistance at other light levels is a concern, please contact the factory. 1 2 3 4 5 6 |
