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