A thermowell provides invaluable triple duty service, by protecting your delicate temperature sensing instrumentation.

- Protects your instrument against corro-sive effects and resulting physical dam-age caused by media flow.

- Permits instrument interchange or cali-bration check without disturbing or clos-ing down the process.

- Helps to contain dangerous or costly pro-cess fluids, when properly installed as an integral part of the vessel or piping.

Basic thermowell types are threaded, flanged, socket weld, weld-in, sanitary and van stone.Shank configurations are available in straight, stepped or tapered styles.Extensive selection of materials are avail-able to meet the demanding applications. Ashcroft’s wide variety of thermowells are available for light duty, high pressures, high temperatures, or high velocity appli-cations as well as meeting many general service industry needs.
