Thermocouple EN 50288-7 Hypron® Isolation XLPE EIEG Armé Non propagateur de l'incendie

Applications

These compensation and extension cables are used with thermocouples for temperature measurements in moist areas and where aliphatic and aromatic hydrocarbons may be present. They are well adapted to underground use in industrial applications where chemical and mechanical protections are needed (refinery areas, chemical plant…). The individual screening of each pair limits the consequence of crosstalk. Hypron ® offers an alternative to conventional lead sheathed cable and is an environmental friendly solution.
