Features and Applications

1. high sensitivity

such5J20110has high thermal sensitivity and resistivity, which can improve the sensitivity of the instrument, reduce the size or increase the force. However, the elastic modulus and allowable stress are low, and the corrosion resistance is poor. Commonly used as non-magnetic non-matching porcelain sealing material in gyroscopes and other electric vacuum devices

2. General Purpose

such5J1480,5J1580, etc. have high thermal sensitivity and high resistivity, good low temperature stability, easy welding, and wide application. Mainly used for heat sensitive components in medium temperature measurement and automatic control equipment

3. Low temperature type

such5J1380in one.70% or less has high thermal sensitivity and high resistivity, suitable for low temperature measurement and automatic control of thermal sensitive components.

4. High temperature type

such5J1070,5J0756has low heat sensitivity, wide linear temperature range, and good oxidation resistance at high temperatures.5J1070suitable300°Cabove ambient temperature,5J0756Wider linear temperature range, the highest operating temperature can reach650°C. Can be used for heat sensitive components in higher temperature and high temperature measurement and automatic control equipment respectively

5. Corrosion resistant type

such5J14140,5J15120has medium heat sensitivity, high resistance and good corrosion resistance, suitable for use in harsh environments or specific corrosive media.

6. resistance type

it is a product that is firmly bonded to a thermal bimetallic component by an intermediate layer made of a highly conductive metal or alloy. By changing the thickness ratio of the intermediate layer, the required resistivity can be adjusted. Resistance type thermal bimetal can be used as thermal relay, circuit breaker, motor overload saturator and other electrical protection devices of thermal components. In the protection device of the same size, as long as the sensitive components of different resistivity are replaced, a variety of different capacity overload protection can be made, so it is conducive to the miniaturization and standardization of electrical protection devices.5J1306,5J1411……5J1455, etc. are resistive thermal bimetallic strips

7. Special type

products prepared according to certain special requirements and with corresponding special properties. Such5JL017, etc.
