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

Applications

These compensation and extension cables are used with thermocouples for temperature measurements. They are well adapted to underground use in industrial applications where hydrocarbons may be present and where chemical and mechanical protections are needed (refinery areas, chemical plant…). The individual screening of each pair limits the consequence of crosstalk.
