Description
- Individual & Overall Screen (IOS)
- Hydrocarbons resistant
Standards
International : IEC 60332-1-2; IEC 60584-3National : NF C 32-070/C2; NF C 42-324
Description
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.
