Cable RTD sensor for plug-in The cable RTD sensors of the TRA-W series are constructed differently and adapted to typical operating conditions. The most important differentiating factor of the cable assemblies is their process connection, the operating temperature range and the insulation material of the connecting cable. Process connection: insertion, fittings: M8, 1/8", 1/4" and 1/2" Execution: insertion variant Temperatur range: -50 … +200°C Material: 1.4404 / AISI 316 L Sheath - Ø: 3, 6 and 8 mm Cable material: PVC, Silicon or Teflon IP protection class: 54
