Pressure Gauges

The Bourdon pressure gauge uses the principle that a flattened tube tends to straighten or regain its circular form in cross-section when pressurized. Although this change in cross-section may be hardly noticeable, and thus involving moderate stresses within the elastic range of easily workable materials, the strain of the material of the tube is magnified by forming the tube into a C shape or even a helix, such that the entire tube tends to straighten out or uncoil, elastically, as it is pressurized. This type of gauge is equipped to meet most of the Industrial applications.

A Chemical ( diaphragm) seal is a flexible membrane that seals and isolates an enclosure. The flexible nature of this seal allows pressure effects to cross the barrier but not the material being contained.

Common uses for chemical (diaphragm) PG seals are to protect pressure sensors from the fluid whose pressure is being measured.

Such type of Gauges are mostly preferred, where pressures are low, thereby eliminating the use of the Bourdon type due to its insensitivity. In such a assembly, the sensing component is a diaphragm, which is connected to the movement assembly through a ‘Ball & Socket’ arrangement. The Pressure to be measured is transmitted through this Diaphragm to the transmission shaft.

The diaphragm offers dual advantage in such type of assembly. Along with increased sensitivity for low pressure measurement it also serves as an Isolation between the process medium and the pressure sensing element.

Such types of Pressure gauges are used for low pressure measurement, in NON corrosive process mediums. The sensing element is a capsule which is made up of dual SS316L laser welded diaphragms. Such type of gauges are preferred for their Accuracy in low pressure measurement. The unique compact design is highly suitable for use in many Industrial applications where space can be a major constraint.

Such types of Pressure gauges are designed to be used in Process Industries where safety requirements are of prime importance. They are strategically designed with a solid front and a Blow out back which is detached from the assembly in case of the Bourdon Rupture, which can happen due to excess pressure developed in the system.

These types of Gauges are Specifically designed to be crevice free with flush diaphragms for all hygienic applications. They contain no filling fluid which would contaminate the process, should a failure of the unit occur. Complying with the most stringent of hygiene regulations, it is available with a full range of connections and operating pressures.

A Indicating Pressure Switch is a form of switch that closes an electrical contact when a certain set pressure has been reached on its input. It offers a dual advantage of Indication and Switching. The switch may be designed to make contact either on pressure rise or on pressure fall. Because of their robust design, they are suitable for harsh environment and most corrosive media and meet stringent demands to bring the advantages of high accuracy, long term stability and protection against water jets and dust on their moving parts.
