Retractable sensor housings with locking system
In harsh industrial processes 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.
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. Intrac 781 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.
