What is a stationary housing or stationary process adaption?

A stationary housing is a piece of hardware that is installed on a vessel or pipe as an entry point for an analytical sensor. These static housings are used for continuous, inline measurement applications of pH, dissolved oxygen, conductivity and turbidity. Stationary process adaptions from METTLER TOLEDO are available in rugged plastic (PVDF, PP), stainless steel and Hastelloy to meet the needs of your process environment. METTLER TOLEDO stationary housings, the InFit range, can be configured to align with your sensor installation requirements.

What are the stationary housing models that METTLER TOLEDO has available?

METTLER TOLEDO offers the InFit range of stationary housings in a variety of models. The InFit 761e series housings are stationary housings for 12 mm sensors with a Pg 13.5 threaded collar. This is one of the most versatile housings due to the wide availability of materials, O-rings, process connections and insertion lengths. The InFit 764e static housings are specifically designed to maximize the performance and longevity of liquid-filled pH and redox sensors. Finally, the InFit 762e and InFit 763e stationary housings are designed for top mount applications in larger vessels and reactors.

Can you move a static housing during the process flow?

Stationary housings are widely used in all industries, providing a secure, durable, and safe way to position sensing devices in a process. Once connected, however, the stationary housing and sensor must be left in place until the process stops or flow is interrupted and the tank or pipe is drained.

What should you consider when selecting a stationary sensor housing?

The primary considerations when a static sensor housing is selected are:

  • Process connection compatibility
  • Insertion length
  • Wetted part materials
  • Process seal materials
  • International compliances e.g. ATEX/ FM approval to be installed in ex-classified area, USP Class VI compliant seals etc.
