    Time response measurements of rosemount pressure transmitters (model 3154) OF Angra I Power Plant
    2017 - SANTOS, ROBERTO C. dos; PEREIRA, IRACI M.; JUSTINO, MARCELO C.; SILVA, MARCOS C.
    This paper shows the Response of time five Rosemount model 3154N pressure trnasmiter from the Angra I Nuclear Power Plant. The tests were performed using the Hydraulic Ramp and Pressure Step Generator from the Sensor Response Time Measurement laboratory of CEN - Nuclear Engineering Center of IPEN. For each transmitter, damping was adjusted so that the time constant was less than or equal to 500 ms. This value has been determined so that the total value of the protection chain response time does not exceed the established maximum value of 2 seconds. For each transmitter ten tests were performed, obtaining mean values of time constant of 499.7 ms, 464.1 ms, 473.8 ms, 484.7 ms and 511.5 ms, with mean deviations 0.85%, 0.24%, 0.97%, 1.26% and 0.64% respectively.
