  • Gage Block Standards Article - Changes Come to Gage Blocks
    New standard forces manufacturers to alter gage block calibration.
  • Gage R&R How and Why
    Gage Repeatability & Reproducibility (GR&R) quantifies the robustness of an entire dimensional measurement system. It does not measure accuracy, accuracy is determined by the calibration of the measurement tools you are using. A Gage R&R is not only used for gages, it's used for: Instruments
  • Reduce Calibration Costs and Improve Sensor Integrity through Redundancy and Statistical Analysis
    as part of the PAT initiative. This paper has demonstrated that we can dramatically improve the data integrity of the critical instrument signals through redundancy and statistical analysis. In fact, one could argue that if statistical calibration is done in real-time, then costly periodic manual
  • Calibration of Harwood Controlled Clearance Free Piston Gages (.pdf)
    Here is presented a method of determining the effective area of the gage at all pressures that does not involve measurements of the effect of jacket pressure on the measured pressure.
  • Squeezing the Most Life From a Zombie Technology
    During his recent presentation at the 2009 Quality Measurement Conference, Ted Dorion of NIST called gage blocks, "a zombie technology." His point was that gage blocks represent calibration standards of the past-indeed, of the 19th century.
  • Impulse Response of 900-Series Biaxial Clinometers Jewell
    The impulse was generated by rotating the clinometer through an angle of 3.4 degrees by pulling a gage block out from under one end of a Model 791 Tiltmeter Calibration Plate. The test was reproduced at three different temperatures using clinometers with undamped (non-viscous liquid) and critically
  • General Procedures For The Use of Load Cells
    to the original calibration performed at Interface. This is because the gage factor (sensitivity of the gages) is affected by temperature. Since heat dissipation in the gages is coupled to the flexure through a thin epoxy glue line, the gages are kept at a temperature very close to the ambient flexure
  • Impulse Response of the 59579-02 Wide-Angle Sensor
    The following graphs show the response of the viscously damped 59579-02 Wide-Angle Sensor to a sudden impulse. The impulse was generated by rotating the tiltmeter through angles of 19.8 and 4.4 degrees by pulling a gage block out from under the tooling ball at one end of a Model 791 Tiltmeter
