Description
The TW20 series of solid-machined weld-in thermowells are suitable for use with numerous electrical and mechanical thermometers from WIKA.
Due to the heavy-duty design, these international design thermowells are the first choice for use the chemical and petrochemical industries and in plant construction.
Features- Different dimensions for standardised welding sockets.
- International standard.
- Possible thermowell forms:.
- Model TW20-A: tapered.
- Model TW20-B: straight.
- Model TW20-C: stepped.
- "Quill Tip" version (with open tip).
