Description
- Overall Screen (OS)
- Lead free
- Aliphatic and aromatic hydrocarbons resistant
Standards
International : IEC 60332-3-22 Cat.ADescription
Applications
These compensation and extension cables are used with thermocouple 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...). Hypron® offers an alternative to conventional lead sheathed cable and is an environmental friendly solution.
