These instruments are designed for chemical, petrochemical industries and for conventional power plants. They are built to resist to the most severe conditions created by the process medium and by the environment and to operate with highly viscous and non-crystallizable fluids. The quality of the materials used to build the sensing element allows to use them in case of high frequency pulsating pressures.
The TIG welding between the case and the process socket strengthens the instrument and assures a better containment of the dampening fluid. The advantages of filling the case with a dampening fluid are: reduced pointer fluctuation, reduced wearing off of movement’s rotating parts when pulsant vibrations and pulsations occur. Moreover, the dampening fluid prevents condensate and corrosive atmospheres from affecting the case and from damaging the internal components of the instrument.
