New InTrac 781/784 series of retractable sensor housings from METTLER TOLEDO.

The new housings meet major international standards including installation in ex-classified area, and pressurized equipment directive (PED 97/23/EC) requirements.

In harsh industrial processes, the safety of workers, the plant and the environment are paramount. Insertion points for in-line sensors can represent a weak spot where leaking process media is a possible hazard. METTLER TOLEDO has developed the InTrac 781/784 series of retractable sensor housings, which are designed to tolerate extreme process conditions. They combine rugged design with installation versatility and ease of use to meet the demands of chemical, petrochemical, pulp and paper, or utilities applications.

An intelligent locking system ensures operating safety at all times. Without the presence of a sensor, the housing's insertion rod cannot be deployed into the process. And the locking system makes it possible to remove the probe only when the insertion rod is fully retracted. This avoids any unintended sensor removal when it is in the measuring position.

InTrac781 and 784 housings allow sensor maintenance and exchange without any interruption to the running process. The stainless steel version of the housing allows sensor deployment or retraction in up to 16 bars with no compromise to operator safety.

New innovations in the design of the integrated cleaning chamber makes sensor cleaning more efficient than ever. Four spray nozzles ensure thorough cleaning of the sensor tip, and the large chamber bore size means dirt and particles are thoroughly flushed out. Operation with METTLER TOLEDO's EasyClean systems is possible for fully automatic sensor cleaning, flushing and calibration (for pH sensors).

Wetted parts are available in different materials (stainless steel 1.4404, alloy C-22, polymer PP, PEEK or PVDF), offering suitability with a wide range of applications. Various immersion lengths and type of process connection are also available, giving excellent flexibility at the measurement point and minimizing re-engineering.

The new housings meet major international standards including installation in ex-classified area, and pressurized equipment directive (PED 97/23/EC) requirements.
