Adtech probe sheaths are made from FEP which offers the best all round properties and excellent shrink properties.
They can be easily shrunk in place at 120 deg. C, yet have a working temperature of 200 deg. C.
The total chemical resistance offered by these probes make them attractive for universal applications, allowing stocking of only one type of probe that can be used for all environments.
ADTECH also offer a probe or sensor coating service.
| Standard Sizes | |
|---|---|
| Probe Dia. mm | Sheath Wall mm |
| 2.8-3.2 | 0.25 |
| 3.8-5.0 | 0.3 |
| 5.5-7.0 | 0.3 |
| 7.0-9.0 | 0.5 |
| 9.5-12 | 0.5 |
| 10-13 | 0.5 |
| 13.2-16 | 0.5 |
All probe sheaths are available with flat or domed
end to
suit the construction of the probe to be coated.

Adtech can also supply any size of PTFE tubing terminated with a welded plug. Adtech have perfected a process for welding PTFE to PTFE.
Each plugged end is electronically tested to 10kV to ensure total integrity of the weld. The benefits of plugged PTFE sheaths are that any size or wall thickness can be supplied from standard PTFE tubing stock.
Capacitance level sensors are commonly covered using this technique. However the sheaths are not normally heat shrinkable.
