The jacketed cable used for making the thermocouples is made up of a continuous metal sleeve, two or four thermocouple wires (simplex or duplex) and mineral insulation.
Mineral insulated jacketed thermocouples are available with Ø 0.25 to Ø 8 mm, and offer the advantage of allowing forming on the site. Properties and benefits: sealed for gases and liquids, bending flexibility up to at least 3 times the outer diameter of the sleeve, high vibration resistance, resistance to high pressure (highly compacted magnesia insulation), compact, short response time. Depending on your applications and requirements, there is an infinite number of combinations of diameter, sleeve length and type of exit. Service range: -200°C to +1400°C, variable depending on mounting.
