Product Introduction
Presentations:
Armor as a platinum resistance temperature sensor, and it fabricated platinum resistance than the diameter of small, easy bending, installed in the pipeline for narrow and rapid response requirements, such as micro-special occasions.
It will be the -200 to 600 ° C temperature range of gases, liquids and solid dielectric surface automatic detection, and can be directly used copper wire connecting instrument and the secondary use, as it has good power output characteristics, it can displays, recording devices regulator, scanners, data recording devices and computers to provide precise input.
Armored protection of the resistance of stainless steel, which is full of high-density insulation material, it has a very strong anti-pollution and excellent mechanical strength, suitable for installation in a poor environment occasions.
Armored platinum resistance usually by armored platinum resistance temperature thermal components, fixtures and the installation of wiring devices, the main component parts.
Features:
The thermal response time less, reducing the dynamic error;
Small diameter, length unrestricted;
High precision measurements;
Imports film resistor element, reliable performance and stability;
Principle:
Armored thermal resistance is to use material changes in temperature, resistance also with the change to the measurement of temperature. When the resistance change, the instrument will work showed resistance value corresponding to the temperature.
Products implementing the standards:
IEC751
JB/T8623-1997
JB/T8622-1997
Insulation resistance at normal temperature:
Thermal resistance at ambient temperature for 15 - 35 ° C, relative humidity of less than 80%, test voltage of 10 - 100V (DC) between the electrode and the jacket pipe insulation resistance> 100 megohms.
