The devices automatically control a predefined process pressure and at the same time measure and/or limit the flow rate. On-the-fly switching between pressure control and flow control offers maximum flexibility.       1 device – 3 functions   The pressure controller combines three functions: – Pressure controller – Pressure controlerl with flow measurement/limitation – Flow controller with pressure measurement       Instrument versions:   – Integrated pressure control: Accuracy:± 0.5 % of full scale, turndown ratio: 1 : 10 – Integrated back pressure control: Accuracy:± 0.5 % of full scale, turndown ratio: 1 : 5 – Pressure control with external pressure transmitters – Pressure controller with gas mixer function       More information:   » Instrument types » Technical overview » Accessories » Documentation, Downloads » Online Quotation » Contact         INSTRUMENT TYPES   red-y smart pressure controller GSP Electronic pressure controller with integrated flow measurement       red-y smart back pressure controller GSB Electronic back pressure controller with integrated flow measurement         TECHNICAL OVERVIEW   Instrument versions flow Standard Accuracy: ± 1.5 % of full scale Turndown ratio: 1 : 30     Hi-Performance Accuracy: ± 0.3 % of full scale + ± 0.5% of reading Turndown ratio: 1 : 100   Instrument versions pressure Pressure control Accuracy: ± 0.5 % of full scale Turndown ratio: 1 : 10     Back pressure control Accuracy: ± 0.5 % of full scale Turndown ratio: 1 : 5       Differential pressure controller according to customer specifications       Performance data Media (real gas calibration) Air, O2, N2, He, Ar, CO2, H2, CH4, C3H8, SF6 Other gases and gas mixtures on request (real gas calibration or conversion factors)     Response time 50 ms     Repeatability ± 0,2% of full scale     Longterm stability < 1% of measured value / year     Power supply 24 Vdc (18 – 30 Vdc)     Current consumption max. 250mA     Temperature 0 – 50°C     Materials Anodized aluminium, optional stainless steel electropolished     Seals FKM, NBR (Valve), optional EPDM     Pressure sensitivity < 0.2% / bar (typical N2)     Temperature sensitivity < 0.025% / °C       Measuring ranges       Flow (Air) Type Measuring range (Air), full scale freely selectable   pressure GSP GSX-A from 0 ... 25 mln/min to 0 ... 500 mln/min   back pressure GSB GSX-B from 0 ... 500 mln/min to 0 ... 5000 mln/min     GSX-C from 0 ... 5 ln/min to 0 ... 50 ln/min     GSX-D from 0 ... 50 ln/min to 0 ... 450 ln/min   Pressure Full scale gauge pressure 0.5 bar ü, 1 bar ü, 2 bar ü, 5 bar ü, 10 bar ü     Full scale absolute pressure 1.2 bar a, 2 bar a, 5 bar a, 10 bar a       Integration Output signals:       - Analog 0..20 mA, 4..20 mA, 0..5 V, 1..5 V, 0..10 V, 2..10 V (for actual value flow only)     - Digital RS-485; Modbus RTU (Slave); Lab View-VI‘s available Option: ProfiBus DP-V0, DP-V1 (for pressure & flow)     Process connection G¼¨ female less than 50 ln/min, G½¨ female less than 450 ln/min     Inlet section non required     Electrical connection Sub D plug, 9 pole     Mounting orientation Any orientation (horizontal only above 5 bar)       Safety Test pressure 16 bar a     Leak rate < 1 x 10-6 mbar l/s He     Environmental protection IP-50     EMC EN 61326-1         ACCESSORIES   Free Software 'get red-y' – View flow rate and temperature – Change setpoints – Select measured gas or gas mixtures – Graphical display of measured data – Adjusting control parameters – Monitor operating state – Totalizer – Optional: Datalogging, gasmixer – Runs on all computers with Windows NT/2000/XP » More Information: www.red-y.com       Control and Readout system PCU1000 – Access to up to 10 smart meters, controllers and    pressure controllers via bus interface RS485 – Setpoint setting for the controllers – Totalizer functions – Gas mixer with up to 12 recipes – Mixing function Master/Slave or fixed value – Automatic instrument recognition:    Serial number, instrumet type, measuring range, etc. – Graphic display (LCD backlit) – Touchscreen – Menu-driven user interface – Operation in several languages – Power supply: 24Vdc – Versions: Panel mount or desktop box » More Information: www.red-y.com         Cables & Modules Cables and Modules for the Thermal Mass Flow Meters and Mass Flow Controllers 'red-y smart series'. » More Information: www.red-y.com         DOWNLOADS   Document Type/Size   Datasheet red-y smart pressure controller PDF/500kB   Data Sheet Software 'get-red-y' PDF/100kB   Data Sheet Readout System PCU1000 PDF/500kB   Data Sheet Cables, Modules & Supply PDF/100kB   Data Sheet Fittings PDF/300kB       » More Downloads           Vögtlin Instruments AG – flow technology – Phone +41 61 756 63 00 – Last Update: 31.05.2010
