| Which insulation Material? | usable temperature range | Application Note |
|---|---|---|
| PVC | -10°C to 105°C | Good general-purpose insulation for “light” environments. Waterproof and very flexible. |
| PFA (extruded) |
-75°C to 250°C | Resistant to oils, acids other adverse agents and fluids. Good mechanical strength and flexibility. PTFE better for steam/elevated pressure environments |
| PTFE (taped & wrapped) |
-75°C to 250/300°C | Resistant to oils, acids other adverse agents and fluids. Good mechanical strength and flexibility. |
| Glassfibre (varnished) | -60°C to 350/400°C | Good temperature range but will not prevent ingress of fluids. Fairly flexible but does not provide good mechanical protection. |
| High temperature glass fibre | -60°C to 700°C | Will withstand temperature up to 700°C but will not prevent ingress of fluids. Fairly flexible, not good protection against physical disturbance. |
| Ceramic Fibre | 0 to 1000°C | Will withstand high temperature, up to 1000°C. Will not protect against fluids or physical disturbance. |
| Glassfibre (varnished) stainless steel overbraid |
-60°C to 350/400°C | Good resistance to physical disturbance and high temperature (up to 400°C). Will not prevent ingress of fluids. |
For maximum accuracy extension cables should be used and terminals and connectors should be of thermocouple materials to maintain continuity.
