EN 837-1/S3 e ASME B40.1 .In case of leaks or break of the elastic element, the operator is protected by a solid separating wall placed on the front of the instrumentand by the blow out back. They are usually used in the food, process, pharmaceutical, petrochemical industries and in conventionaland nuclear power plants. The TIG welding between the case and the process socket, strengthens the instrument and assures a bettertight in case of dampening fluid. The advantages of filling the case of the instrument with a dampening fluid are: reduced pointerfluctuation, reduced wear of rotating parts of the movement when pulsant vibrations and pulsations occur. Moreover condensationand corrosive atmospheres which could damage the internal parts are prevented. Standard ModelDesign: Fillable Model - Lower connection onlyProtection degree: EN837-1.

For use in potentially explosive atmospheres, instruments must be designed in conformity to ATEX 94/9/CE. This versionis shown on separete data sheet available on request. These instruments are built in conformity with the construction and safety specifications of Blow out disk: stainless steel. Window: safety glass. Movement: stainless steel with internal limit stops for minimumand maximum pressure. Dial: aluminium, white with black markings.

INSTRUMENTS FOR OXYGEN

Pointer: adjustable, aluminium, black.
Glicerine or silicone should not be used with highly oxidizing agents suchas oxygen, chlorine, nitric acid or hydrogen peroxide, because of danger of spontaneous chemical reaction, inflammability or explosion. The use of fluorinates fluid is recommended in these cases.
