Detail:
Sheathed platinum resistance as a temperature sensor, it is smaller than the diameter of the assembly type platinum resistance, easy to bend, suitable for installation in narrow tube and rapid response, miniaturization, and other special occasions. It can automatically detect gas, liquid medium and solid surface of -200~600, and can be directly connected with the copper wire and the two meter. As it has good electrical output characteristics, it can provide accurate input values for the display instrument, recorder, regulator, scanner, data recorder and computer.
Armoured resistance outside protective pipe is made of stainless steel, full of high density oxide insulator material, so it has very strong anti pollution and excellent mechanical strength, suitable for installation in the harsh environment of the occasion.
Sheathed platinum resistance usually consists of a sheathed platinum RTD temperature sensing element, the main components of mounting and fixing device and a wiring device, etc..
Characteristic
The thermal response time is little, and the dynamic error is reduced;
- small diameter, length is not limited;
High accuracy of measurement;
- import film resistance element, stable and reliable performance;
Working principle
Armor thermal resistance is the use of the material when the temperature changes, the resistance change of temperature measurement. When the resistance changes, the instrument will display the corresponding resistance temperature value.
Main technical parameters
Product implementation standard
IEC751
JB/T8623-1997
JB/T8622-1997
Insulation resistance at room temperature
Thermal resistance at ambient temperature of 15 - 35 C, the relative humidity is not greater than 80%, the test voltage is 10 - 100V (DC) electrode and the insulation resistance between the jacket tube >100M.
