There is no significant passage of gases through the body at high temperature except under high vacuum.
Ceramic thermocouple well.
Designed for use with thermocouples and rtds in large nonpressurized tanks these protection tubes are available in long lengths at a lower cost than thermowells.
Ceramic protecting tubes primary secondary.
Such conditions usually require a noble metal thermocouple such as platinum or platinum alloys.
For the usual industrial application it is sufficiently impermeable.
A leading manufacturer of quality thermocouple and rtd assemblies.
Thermocouple and rtd protection tubes.
316 stainless steel protection tubes are extremely resistant to corrosive chemicals and they can handle higher temperatures than steel.
Designed for use with thermocouples and rtds in large nonpressurized tanks these protection tubes are available in long lengths at a lower cost than thermowells.
Ceramic protecting tubes primary.
Steel and 316 stainless steel protection tubes are more durable than ceramic protection tubes.
Product and ordering information.
For example so 2 and so 3 gases have not penetrated lt 1 thermowells over a three year period to affect thermocouple.
Thermosensors manufactures thermowells with ceramic protecting tubes with double threaded bushing and come without fittings.
Ceramic protection tubes are used for applications where contamination from hostile environments or the cutting action of concentrated and direct flame impingement are factors.
