Held every year in June at the Donald E. Stephens Convention Center near Chicago’s O’Hare airport, SENSORS EXPO brings together a wide selection of exhibitors representing manufacturers of wireless, pressure, gas, flow meters and other related technologies. This year’s awards went to Gold, Silver, Bronze and Honorable Mentioned awards in the areas of Sensor, Sensor Components, Technologies and Data Acquisition.
The PRISM AWARD is given in 9 categories and recognizes the best innovations in the field of optical and photonic technologies and products.

Since 2002 a wide range of current-mode detectors with integrated CMOS OpAmp instead of a JFET source follower has been brought on the market.
Dual channel detectors like the LIM-252 from InfraTec are needed to measure gases.
Dual channel pyroelectric infrared detectors (Channel1 = sample gas, and Channel2 = optical reference) are used in sensor modules of many manufactures that build NDIR Gas analyzers. The 4-pin TO39 package in which the Pyroelectric chips are integrated, along with JFETs and high Ohm resistors is a standard.
