금속의 전기저항은 온도에 따라 변화 합니다. 그 중에서도 고순도의 백금은 이 관계가 다른 금속에 비교하여 직선적이고 온도계수도 커서
온도측정용으로 적합합니다. 또 화학적 물리적으로도 우수한 성질을 가지고 있어서 공업적으로 쉽게 정밀한 저항값을 얻을 수 있는 온도
측정용 저항소자로서 장기간 안정된 사용이 가능합니다. 특성은 국제표준규격에 의해 규격화 시켯으며, 고정도의 온도 측정이 가능합니다. |
In general, metal electric resistance varies according to temperature changes. Platinum is more linear and carries larger temperature coefficient than most other metals with different relations, and the product therefore is suitable for temperature measurement. In adition, as the platinum carries excellent chemical and physical properties, the product can be used for a long period of time in a stable condition as a temperature measuring resistance element capable of easily and industrially obtaining accurate resistance values. The characteristics have been standardized based on intermational standards, ensuring high-accuracy temperature measurements. |

2.Internal lead wire 3.Insulator 4.Protection tube This protectin tube protects resistance elements, and internal wires from surrounding conditions, to which components and terminal heads are connected. As the operating temperature, atmosphere and purposes of the protection tube vary considerably according to the temperature checking places, it is necessary to select materials and shapes which suit conditions.
