    Thermocouple and RTD Protection Tubes

    Image of Product. Front orientation. Contains Annotated. Thermocouple and RTD Protection Tubes.
    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.
    Steel—Steel protection tubes are more durable than ceramic protection tubes.
    316 Stainless Steel—316 stainless steel protection tubes are more durable than ceramic protection tubes. They are extremely resistant to corrosive chemicals, and they can handle higher temperatures than steel protection tubes.
    Ceramic—Ceramic protection tubes withstand temperatures nearly twice as high as 316 stainless steel protection tubes.

    Thermowells

    Image of Product. Front orientation. Contains Annotated. Thermowells. Thermowells.
    Protect thermometers and temperature probes from pressure, vibration, shock, and corrosion in tanks and pipelines. These thermowells isolate the contents of your process, so you can replace temperature sensors without stopping flow or draining the system.
    304 Stainless Steel—304 stainless steel thermowells are more corrosion resistant than brass thermowells.
    316 Stainless Steel—316 stainless steel thermowells are extremely resistant to corrosive chemicals.
