Description
TA550 is an industry standard
thermowell, manufactured from round bar
stock (drilled).
The process connection can be threadedor flanged weld.
The thermowell stem shape can bestraight or conical.
The extension and the immersion lengths
as well as the bar dimensions can bechosen according to process
requirements.
A wide choice of standard materials andprocess connections is available; otherversions can be ordered according tospecification.
Different grades of surface finishing arealso available.

Flangedprocess connection

Application
TA550 is designed for use with resistanceand thermocouple thermometers mainly
in heavy duty applications.
