Abstract

The Mexican National Metrology Center (CENAM) has installed a Dead Weights Force Standard Machine as national standard with a measuring range up to 153.6 kN (MMS-150 kN), which allows to carry out calibrations of force transducers in traction or compression mode. This machine has an automatic system which permits, by a series of comparisons with well known masses, to perform a calibration procedure in three different modes (high accuracy, low accuracy and special procedures). This force standard facility gives traceability to measurements (and calibrations) made by the net of secondary calibration laboratories in Mexico by means of their secondary force standards calibration. The instruments that can be calibrated in the MMS-150kN are high accuracy load cells, force transducers and proving rings. This paper describes the improvements in the data acquisition, signal processing and automatic control implementation to obtain the readings of the calibration process.
