4 1 /2" PROCESS GAUGES 600/700 SERIES GENERAL INFORMATION NOSHOK 4-1/2 Inch 600 (Brass) and 700 (316SS) Series Process Gauges are specifically designed for demanding applications in the chemical and petroleum processing industries, as well as many industrial applications. The turret style cases are constructed of a rugged, corrosion resistant phenolic material. The solid front, safety case design with a blow-out back isolates the gauge face from the pressure measuring system and assures operator protection if ever needed. The standard lenses are a shatter resistant acrylic, and safety glass lenses are available. The heavy-wall bourdon tubes and connections are made of copper alloy and brass (600 series) or all 316 stainless steel (700 series). "C" tubes are used on pressure ranges through 600 PSI and coiled safety tubes are used on pressure ranges above 600 PSI. The bourdon tubes are then matched with precision movements of similar materials - brass movements in the 600 Series and stainless steel movements in the 700 Series. The pointers are balanced and micro-adjustable. Liquid filled models are also available to further enhance gauge life and incorporate a unique breathing diaphragm that limits the effect of calibration changes due to ambient pressure and temperature changes. Applications for NOSHOK 4-1/2 Inch 600 and 700 Series Process Gauges include service in chemical, petroleum and petrochemical refineries and pumping stations, food processing plants, power generating stations, water treatment plants and pulp and paper plants. They are widely used throughout industry where accuracy, readability, safety and reliability are important. OPTIONAL LENSES Both Instrument Glass and Laminated Safety Glass are available on all 4-1/2 inch 600 and 700 Series gauges. LIQUID FILLING OPTIONS All 4-1/2 inch 600 and 700 Series gauges are available in a liquid filled version. Our standard fill is glycerine and water; however, optional fill liquids include 1 Dow Corning 200 Silicone and 2 Halocarbon. A Liquid Filling Kit (LFK) is also available to convert dry gauges in the field. Each Liquid Filling Kit (LFK) includes a vented blow-out back with breathing diaphragm (for internal case pressure compensation) and O-ring. Fill liquid is not included. REID VAPOR TEST GAUGES A Reid Vapor Test Gauge configuration which includes a handle, special dial and special pressure part is available in pressure ranges of 0-5 PSI, 0-15 PSI and 0-30 PSI. RECEIVER GAUGES 3-15 PSI Receiver Gauges are available in both 600 Series (Brass) and 700 Series (316SS) configurations. METRIC AND HANDMADE SPECIAL DIALS Dual scale Metric Dials in PSI/kPa and PSI/Kg-cm 2 are available on all 600 and 700 Series gauges. Handmade Special Dials such as non-standard metric scales, tons on ram, lbs. of force, etc. are available in small quantities (as few as one piece) on all 600 and 700 Series gauges. ORIFICES Threaded Orifices (.032" I.D.) are available on all 600 and 700 Series gauges. Orifices are used on a gauge to restrict the flow of rapidly increasing and decreasing pressures, thereby less- ening the immediate effect of pulsations and pressure spikes. Orifices are recommended on all dynamic applications. CERTIFIED CALIBRATION Certified Calibration is available on all 600 and 700 Series gauges. Certified Calibration provides the user with a serial number gauge along with a calibration sheet against a pressure standard and is traceable to the National Institute of Standards and Technology (formerly National Bureau of Standards). 1 Dow Corning-A registered trademark of Dow Corning Corporation. 2 Halocarbon-A registered trademark of Halocarbon Products Company.
