Beamex® MC2 and Beamex® MC2-IS – a series of 4 different practical calibrators. The MC2 series includes four different portable calibrators MC2 Main features Available in three versions: MC2 Pressure/Electrical Calibrator MC2 Temp./Electrical Calibrator MC2 Multifunction Calibrator Internal / ...
In this work, research being carried out for the development of suitable practical calibration methods will be presented. The behavior of copper crushers under different high strain rates by the use of the Split Hopkinson Pressure Bars (SHPB) technique is investigated in particular. The Johnson-...
A. BERMAN, in Total Pressure Measurements in Vacuum Technology, 1985 5.2.1 The Calibration Chamber It must be possible to achieve in the calibration chamber a uniform and stable distribution of calibration gas at the ports of the chamber where the gauge heads undergoing calibration are attached. ...
so a benchtop calibration is often the most practical option whencalibrating analog gauges. Labs are climate controlled and use pressure references with higher accuracy than those typically used in the field. And when tasked with testing multiple gauges that require different levels of pressure, bench...
Mechanical parts wear, electronic components drift, so instruments that have mechanical parts (like the material that makes the diaphragm type sensors in a pressure gauge) or electronic components (like every digital multimeter made) will also drift and perform differently over time.Metrologist with ...
The line pressure and vacuum to this module is via the 7149 and 7165 electric pumps, meaning no need for an external supply. For higher range pneumatic work, a 100 bar (1500 psi) regulated module with digital gauge provides a practical calibration method with high accuracy referen...
Johnson [129] suggested that calibration can be made independent of material composition, material heat treatment and thickness of test-piece but sensitive to the starter notch geometry. This principle enables a single calibration curve determined for a standard specimen to be applied to practical ...
