Thermocouples Type T
for thermal validation and qualification
Bakrona supplies prefabricated Type T thermocouples, ideally suited for demanding validation tasks in the pharmaceutical, biotech, and medical technology sectors. Our thermocouples made of copper/constantan (Type T) are available with tight tolerances according to special limits as well as premium grade. Additionally, we offer thermocouple wires and strands in rolls, ideal for custom configurations and special requirements.
The thermocouples are commonly used with various validation systems such as the Ellab E-Val Pro system, Kaye AVS, or Validator and can be reliably integrated into existing processes.
Our product range covers applications in hot air sterilizers, sterilization tunnels, steam autoclaves, SIP systems, freeze dryers, and liquid-carrying systems. Depending on the area of use, high-temperature resistant cables with Kapton or PTFE/PFA insulation are used. The thermocouples are characterized by high measurement accuracy, mechanical robustness, and GMP-compliant quality.
Overview of Type T Thermocouples with PTFE/PFA and Kapton Insulated Cables
| Type / Article | Insulation Material | Application Area | Special Features |
|---|---|---|---|
| 1TB11 | PFA | Needles, syringes, freeze dryers | Very thin cable, for tight spaces & surface measurement |
| 7TB19 | FEP | Steam autoclaves, SIP | For measurements in steam and air |
| 7TB25 / 7TB30 | FEP | Large containers, fermenters, liquids | Robust design for large-volume systems |
| 7KB17 | Kapton | Hot air tunnels | Drag probe on conveyor belt |
| 7KB20 | Kapton | Hot air chambers | Very flexible, easy handling |
| 7KB23 | Kapton | Hot air chambers | Slightly stiffer – alternative to 7KB20 |
Temperature Range of Thermocouple Insulation
| Insulation type | Application temperature of the thermocouples |
|---|---|
| FEP | -200 °C to 200 °C continuously, 260 °C peak |
| PFA | -200 °C to 260 °C continuously, 300 °C peak |
| Kapton | -200 °C to 260 °C continuously, 350 °C peak |
Type T thermocouples are available with compensated plugs and panels; standard design up to 205 °C and high-temperature version up to 425 °C.
Type T Thermocouples with FEP Insulation for Steam Sterilization in Autoclaves
Sealed measuring tip for autoclaves, CIP-SIP systems, bioreactors, fermenters:
| Type | Specification |
|---|---|
| 7TB30 | Robust 7strands wire, FEP insulated. Old standard version (1.8x3.0 mm) for Kaye Validator and Digistrip |
| 7TB19 | Thinner yet durable 7strands wire, FEP insulated, as a replacement for the mechanically fragile 3strands wire |
| 7TA26 | Autobond 7 strands wire, FEP insulated as alternative to 7TB30. The special cable design prevents the penetration of moisture along the wire |
Type T Thermocouples with PFA Insulation for Freeze Drying
Smallest possible dimensions of the measuring tip for surface measurement of cooling plates and for measurement in the product:
| Type | Specification |
|---|---|
| 1TB11 | Very thin 1-strand PFA insulated thermocouples |
Type T Thermocouples with Kapton Insulation for Hot Air Sterilization
Type T Thermocouple with fast response measuring tip and small dimensions for hot air sterilizers and hot air tunnels:
| Type | Specification |
|---|---|
| 7KB23 | Robust 7 strands wire, Kapton insulated, for bottles. Old standard version (1.3x2.3mm) for Kaye Validator and Digistrip |
| 7KB17 | Thin yet robust 7 strands wire, Kapton insulated, for ampoules and vials |
| 7KB15 | Very thin 7 strands wire, Kapton insulated, to measure in small containers |
Compensated plugs and panels for thermocouple connections
Mechanically robust and electrically reliable plugs, sockets, and panels made from thermocouple materials enable easy connection and quick joining of thermocouples.
