BDTW2X2 FLANGED PROCESS CONNECTION

Transcription

1 Badotherm thermowell model TW2x2 is a bar stock type thermowell with a flanged process connection. The construction is available with straight, stepped, or tapered stem. The standard material is AISI 36(L) and optionally various exotic materials are available. Thermowells are designed to protect the temperature bulb from corrosive effect, extreme pressure, or other process conditions. It also allows replacing the temperature instrument without disturbing the process.
