High Temperature Compensation Wire
Description:
A brief introduction, conductor:
Temperature compensation wireThe effect is to extend the thermode that cold end of thermocouple temperature measurement system and display instrument is connected.High temperature thermocouple compensation wire insulation layer and protective layer according to the environmental requirements of the selected material is not the same, PVC sheath material, fluorine plastic, low smoke and low halogen PVC and alkali free glass wire several imported high-quality fluorocarbon can be high temperature of 260 DEG C, and the continuous extrusion process, make the product has excellent acid resistance, alkali resistance, and flame extension performance, can be used for a long time in oil.
Temperature compensation wireThe use of temperature in - 60 - 260 C, which belongs to the contemporary domestic advanced level.Series of products are mainly used in various types of temperature measuring device, according to the variety of products is divided into SC, KC, KX, EX, JX, TX, NC.
Two, the implementation of standards: GB/T4989/94 equivalent to IEC584.3,
Three, use range:
Temperature compensation wireApplicable to energy, metallurgy, petroleum, chemical and other industrial enterprises and scientific research departments, the temperature control system.For the connection between the cold end temperature measuring instrument and temperature measuring instrument.Heat type imported fluorine plastic insulated and sheathed with excellent heat resistance, waterproof, anti-corrosion, anti acid, chemical resistance, resistance to abrasion, aging and combustion performance.Use temperature of -60 to 260 DEG C, is the international advanced level.
Three, the conditions of use:
(1): highest working temperature: heat with 200 degrees and 260 degrees two;
General: a maximum of 70 degrees and 105 degrees two.
(2) the lowest ambient temperature: fluorine plastic insulated and sheathed cable laying: -60 C -20 C non fixed installation;
PVC insulated and sheathed cable laying: -40 C -15 C non fixed installation.
(3) the minimum bending radius: PVC insulated and sheathed cable non armored cable is not less than 6 times of cable diameter, 10 times of fluoroplastic insulation and sheath for non armored cable is not less than the diameter of the cable, not less than 12 times of cable diameter for armored cable.
Four,Temperature compensation wireThe use of characteristics:
type | The minimum bending radius | The lowest temperature | Maximum temperature |
Unarmored | Armoured | Fixed installation | Non fixed installation |
General type There are 105 types of "" There are 90 types of "" High temperature type | 6 times of the cable diameter 10 times of the cable diameter | 12 times of the cable diameter | C = -40
C = -60 | C = -15
C = -20 | Less than or equal to 70 DEG C Less than or equal to 105 DEG C Less than or equal to 90 DEG C Less than or equal to 250 DEG C |
