Title (EN) TEMPERATURE COMPENSATION OF A TEST TONE USED IN METER VERIFICATION
(FR) COMPENSATION DE TEMPÉRATURE D'UNE TONALITÉ DE TEST UTILISÉE DANS LA VÉRIFICATION D'UN APPAREIL DE MESURE
Abstract:
(EN) A method for temperature compensation of a test tone used in meter verification is provided. The method uses a drive amplifier to provide a drive signal to a drive circuit, wherein the drive circuit includes a drive mechanism in a meter assembly of a vibratory meter. The method measures a first maximum amplitude of the drive signal at a first temperature of the drive circuit, and measures a second maximum amplitude of the drive signal at a second temperature of the drive circuit. The method also determines a maximum amplitude-to-temperature relationship for the drive circuit based on the first maximum amplitude at the first temperature and the second maximum amplitude at the second temperature.
(FR) L'invention concerne un procédé de compensation de température d'une tonalité de test utilisée dans la vérification d'un appareil de mesure. Le procédé utilise un amplificateur d'attaque pour fournir un signal d'attaque à un circuit d'attaque, le circuit d'attaque comprenant un mécanisme d'attaque dans un ensemble appareil de mesure d'un appareil de mesure de vibrations. Le procédé mesure une première amplitude maximale du signal d'attaque à une première température du circuit d'attaque, et mesure une seconde amplitude maximale du signal d'attaque à une seconde température du circuit d'attaque. Le procédé détermine également une relation amplitude maximale-température pour le circuit d'attaque sur la base de la première amplitude maximale à la première température et de la seconde amplitude maximale à la seconde température.
