The isolated thermocouple safety barrier SWP8081-EX and the thermal resistance safety barrier SWP8083-EX combine the functions of a temperature transmitter and an isolated safety barrier into one, featuring high precision, high reliability, and high safety, and are widely used Oilfield, petrochemical, electric power, metallurgy and other industries in the DCS system.
Thermocouple safety barrier SWP8081-EX | Thermal resistance safety barrier SWP8083-EX Features
1, the temperature isolation safety barrier analog transmission accuracy of 0.5% F.S.
2, temperature drift: 0.02% F.S.
3, resistance and galvanic input channel circuit designed to double the circuit, so that the system's security and reliability have been effectively improved.
4. The intrinsically safe circuit is isolated from non-intrinsically safe circuit transformers and has no direct connection. The isolation withstand voltage is up to 150Vms.
5, fast fuse has a fast and high breaking capacity, breaking capacity of 250VAC voltage. Meet the latest intrinsically safe circuit international standards.
6. The overall package of power transformer and signal transformer eliminates the possibility of snapping and reaching of components. The product has high reliability and safety.
7. The products use high-quality imported brands of semiconductor devices, automated SMT chip manufacturing processes, and modern testing equipment such as computers to test products to ensure reliable products.
8. The product design circuit is fully optimized and designed according to the requirements of international electromagnetic compatibility standards.
9. Each product is subjected to high-temperature aging before leaving the factory. The quality is guaranteed absolutely.
