온도는 PYS의 양이 0.01 mol% 증가함에 따라 10℃씩 감소하였다.
(3) 분극 조건은 능면정계에서는 80℃, 20㎸/㎝를 인가한 후 20분을 경과시키면 포화상태에 이르는 것으로 나타났으며, 정방정계의 경우에는 80℃, 50㎸/㎝ 이었다.
(4) 조립특성은 PYS가 0.05 mol% 첨가된 조성 중 RIST 5에서 상온 노이즈 및 상온 감도가 가장 우수한 것으로 판명되었다.

Abstract
Non-contact IR temperature sensor were prepared to set-up the system that can watch the temperature variation of BUS-BAR constantly. PZT-PYS ternary system was developed as the optimum composition of the piezoelectric material composing IR temperature sensor. Room temperature noise and sensitivity characteristics with 0.05mol% PYS were better than other cases. Specially, the composition of RIST 5 showed the best oven noise characteristics.
Key words : Non-contact IR temperature sensor, PZT-PYS ternary system, Poling condition, Oven noise
