SOLFRUNT ® Solid Front 4-1/2" Model 1981 and Model 1981 Advantage Gauges with Dampened Movement - 1

Product Data PROCESS GAUGES SOLFRUNT ® Solid Front 4-1/2" Model 1981 and Model 1981 Advantage Gauges with Dampened Movement DESCRIPTION The Solid Front Model 1981 and 1981 Advantage 4-1/2" process gauges have all 316L stainless steel wetted surfaces with a seamless Bourdon tube. The 1981 Advantage includes a dampened movement option to provide users with some of the benefits of liquid filling. These gauges have a PET turret style case for chemical and petrochemical processing applications. The PET material gives this case superior impact strength and a broad spectrum of chemical resistance. They are available dry, with a dampened movement, or liquid filled from the factory. Your local stocking distributor can provide a liquid fill kit, or the EZ Fill design to facilitate filling in the field without special tools. The Model 1981 and 1981 Advantage 4-1/2" SOLFRUNT gauges are supplied in 26 vacuum, compound, and pressure ranges from 30" Hg vacuum through 11600 psi. The low-connected PET turret case can be easily liquid filled in the field using the appropriate conversion kit. Span adjustments can be accomplished from rear of case without disturbing the gauge internals. Pointer adjustments are easily made by removing ring and window, and using the adjustment screw on the micro-adjustable pointer. ACCURACY: ±0.5% of span (Grade 2A), except where seamless stainless steel bourdon tubes are used in following ranges: Type 316L from 10000 to 11600 psi; accuracy is ±0.5% on ascending pressure and ±1.0% on descending pressure BOURDON TUBE: 316L seamless stainless steel/TIG welded WINDOW: High temperature acrylic, laminated shatter-resistant glass options available (G038312) MOVEMENT: Geared movement with components of corrosionresistant 300 series stainless steel; optional dampened movement available on Advantage unit DIAL: Aluminum with baked white background and black markings; optional luminescent or high visibility bright yellow dial (dual scale and custom dials available) POINTER: Anodized aluminum, micro-adjustable with black finish; optional red pointer or lazy hand (lazy hand can only be used on dry gauges, #132371) CASE AND RING: For Stem or Wall Mounting: PET turret case (black) with glass-filled polypropylene threaded ring and pressure-relieving back, EZ Fill option available CONNECTION: 316L stainless steel, 1/2-14 NPT standard (1/4-18 NPT, optional) LIQUID FILLING: The Model 1981 is also available in liquid filled or field fillable (EZ Fill) configurations.
