Description
- Individual & Overall Screen (IOS)
- Hydrocarbons resistant and enhanced resistance to aromatics
Standards
International : IEC 60332-3-22 Cat.A; IEC 60584-3National : 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, in moist areas, where chemical and mechanical protections are needed. The lead cover brings an enhanced resistance to aromatic hydrocarbons. The individual screening of each pair limits the consequence of crosstalk.
