Scope

Scope: This document specifies the model names, requirements, inspection methods, inspection rules, marking, packaging, transportation, and storage of piezoelectric ceramic components used in marine seismic exploration solid tow cables piezoelectric detectors (hereinafter referred to as detectors). This document applies to piezoelectric ceramic components for detectors (hereinafter referred to as products). Main technical content: (1) Free capacitance CT = 10.50 ± 1.05 nF, determined based on the actual matching between the capacitance and sensitivity of the piezoelectric detector. (2) Longitudinal piezoelectric strain constant d33≥600 pC/N, determined based on the actual needs of the piezoelectric detector's reception sensitivity. (3) Curie temperature Tc≥210℃, determined based on the temperature stability requirements of the piezoelectric detector.
