SOLFRUNT 656 Series Gauges

Product catalog summary

Specifications:
The document outlines the specifications for Model 6562 and 6566 pressure gauges. Model 6562 (63 mm) has an accuracy of +1.6% of full scale, while Model 6566 (100 mm) has an accuracy of +1.0% of full scale. The pressure range for Model 6562 is from 30 inch Hg to 0 psi up to 10,000 psi, and for Model 6566, it is from 30 inch Hg to 0 psi up to 23,000 psi. Both models have a steady working pressure at 50% of full scale and over-range protection at 125% of full scale. The working temperature ranges from -40°F to 140°F ambient and -4°F to 176°F fluid.

Materials and Construction:
The pressure connection and Bourdon tube are made of 316L stainless steel, while the case and bezel ring are made of 304 stainless steel. The 63 mm model features a polycarbonate window with an optional laminated shatter-resistant glass, and the 100 mm model comes with a laminated shatter-resistant glass window.

Applications:
The 656 Series gauges are designed for corrosive environments in industries such as chemical, petrochemical, refining, power, marine, and food and pharmaceutical processing. They are particularly effective in environments with excessive vibration and pulsation due to their liquid-filled design, which minimizes environmental effects and extends service life.

Warnings and Recommendations:
Users are cautioned that fill fluids can react with strong oxidizing agents, potentially causing explosions. It is recommended to consult the factory for alternatives if gauges are to be used in such environments. Familiarity with the ASME B40.100-1998 standard for pressure gauges is advised.

Ordering Information:
The document includes an ordering guide detailing nominal diameters, pressure ranges, units of measure, mounting types, accuracy, and connection types. Metric and dual scale dials are available upon request.
