Mettler Toledo introduces retractable sensor housings

November 24, 2015 -  MettlerToledo introduces InTrac 781/784 retractable sensor housings with an intelligent locking system that 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 bar with no compromise to operator safety.

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