This thermocouple assembly is designed for composite curing and vacuum oven processes where standard fibreglass-based probes degrade in handling and become contamination risks. It prioritises mechanical toughness, cleanability, and handling stability while remaining fully rated for typical cure temperatures. The result is a reusable sensor that is easier to deploy, maintain, and keep accurate across repeated cycles.

Key Features

  • PTFE with stainless steel underbraid construction – provides abrasion resistance and structural support without the contamination and fibre shedding risks associated with fibreglass braids.
  • Reduced cable memory effect – improves handling and routing inside vacuum bags and ovens, making the lead easier to position and keep organised during setup.
  • Exposed bead junction – delivers fast thermal response, improving tracking of surface temperature changes during cure cycles.
  • Class 1 accuracy (Type K) – supports reliable temperature measurement within defined tolerance limits for process control.
  • Supplied with round pin connector – suitable for connection to fixed thermocouple sockets inside ovens and autoclaves.
  • Reusable design – optimised for repeated use through improved mechanical durability and resistance to flex-related damage.
  • Smooth, sterile cable finish – simplifies cleaning and reduces contamination retention in composite processing environments.
  • 200 °C full assembly rating – entire sensor, including connector, is suited to typical composite curing conditions.
  • Custom lengths available – enables configuration for specific oven layouts or process requirements.

Composite Curing and Vacuum Oven Use

In composite manufacturing, thermocouples are typically attached directly to the part surface under a vacuum bag and routed to a fixed connector inside the oven or autoclave. In this environment, conventional fibreglass-braided probes can degrade under repeated handling, trap contaminants, and become difficult to manage due to cable stiffness and memory.
This assembly addresses those limitations by using a PTFE outer with stainless steel underbraid, maintaining sufficient temperature capability for cure processes while improving mechanical resilience and usability. The exposed bead junction allows rapid response at the measurement point, supporting tighter control of cure profiles. The smooth outer surface also allows easier cleaning between cycles, which is relevant in contamination-sensitive processes.
Designed for composite technicians requiring a reusable, mechanically robust thermocouple that maintains performance through repeated curing cycles without the handling and contamination drawbacks of fibreglass designs.
