Displacement measurement sensor for use in Loss-of-Fluid-Test reactor

Conference ·
OSTI ID:5580220
Qualification tests conducted for a period of 700 hours of each of three displacement measuring (LVDT) sensors confirmed applicability of the design for use in the Loss-of-Fluid-Test (LOFT) reactor. Operationally, the sensor satisfies all specified requirements for LOFT. Even for imposed temperature transients at rates up to 100/sup 0/F/s, the indicated displacement remained within the allowed maximum error band of +-10% of reading. The 0.625-inch O.D. by 5.5-inch long sensor exhibited a linearly related signal output variation for displacement variations of up to 1-inch range. Long term operation at temperatures of 100/sup 0/F to 800/sup 0/F caused no perceptible permanent change of operating characteristics. 8 refs., 14 figs.
