Air-Purge Jacket keeps temperature sensor lenses clean.
2015-01-20 14:30:45| Industrial Newsroom - All News for Today
Designed to work with IRt/c and Micro IRt/c.4 sensors measuring 3/8 in. dia x 3 in. long, Micro Clean Micro Air-Purge Jacket prevents oil, dust, condensation, and other debris from obscuring lens and degrading sensor readings. Miniature-sized lens and efficient jacket design make it possible to clean surface with as little as 0.06 cfm of air, and to use instrument air, eliminating need for additional hardware. In addition to keeping lens clean, jacket cools sensor, allowing operation up to 347°F.
