• IR Characterization of Bi-Propellant Reaction Control Engines During Auxiliary Propulsion Systems Tests at NASA's White Sands Test Facility In Las Cruces, New Mexico
  instrumentation engineers that we work with have traditionally. preferred only TCs for monitoring test articles such as rocket engines, since the emissivity changes rapidly as. they heat up, causing anomalous temperature results. In addition, their benefit was mostly considered. supplemental...
• Guess the Real World Emittance (.pdf)
  is a special case and emittance refers. to real world targets with all their holes and blemishes. TEST YOUR KNOWLEDGE. In order to give us all a better understanding of how improbable it is to "guess" the emissivity of a metal target. by just using our eyes, Table 1 lists pictures of all test specimens up...
• Advanced Hypersonic Material Technology Program
  , University of Alabama in Huntsville, Huntsville, Alabama May, 2002. Hypersonic Convective Test. Density = 78.0 lb/ft3. Test #3 - RX2390 -2. TC1. TC4 TC5. Delta T = 75.5 oF. .344". Position 4. TC3. Average Thickness = .3. Flow. TC2. Pre-Test Emissivity = .9. Post-Test Emissivity =. 1100. 1000. 900. 800...
• Evaluation of Plasma Facing Components Thermal Performance by Infrared Thermography (.pdf)
  Cadarache. SATIR facility is now identified as the basis test to elaborate acceptance criteria of CFC armoured PFC. This. paper deals with all the improvements performed on test bed to meet a reliable examination of high. performing fusion PFC. INTRODUCTION. International Thermonuclear Experimental...
• Purchasing and Using IR Thermometers
  laser sighting system for estimating the IR. measurement area. Higher-end models also have data logging and emissivity settings that. can be adjusted for greater accuracy on specific materials and objects. Prices for these. models typically range from $200 to $500. At the highest end, IR...
• Using IR on Insulated Pipe System
  there was liquid under the stainless steel. covering. In each of these cases, an emissivity corrector was needed. The stainless steel covering. emissivity is too low and too reflective to give a reliable IR image. The test indicated that there was not enough energy concentration to find a suspect corroded...
• Characterizing a rapid thermal annealing process to improve sensor yield
  , and we are evaluating the processing of those test wafers through the RTP system as a second source of temperature information. A data-logging system for monitoring all input variables (including external facilities inputs as well as internal control data) is also being implemented. Finally...
• Reducing Hydraulic System Temperatures (.pdf)
  . INTRODUCTION. DMAX, Ltd. builds the Duramax Diesel engine for use in General Motors heavy duty trucks. At our facility the. engine block, head, crank, and connecting rod are machined. These parts are used in our assembly area. where we build and test the engine. The problem occurred on a cylinder block...
• MICRO: Product Technology News (July '2000)
  temperature control that is independent of ripple emissivity, providing repeatable results regardless of variations in wafer backside conditions. The system also maintains a total components of variance of +-2 C. The system features a slip-free ring that completely surrounds the wafer to eliminate edge...
