5 GUARDIAN INDUSTRIAL & ATEX SWITCHES INTRODUCTION The Gurdin pressure, differentil pressure, temperture, level nd flow swithes re prt of our extensive rnge of speilist proess sensors. They utilise the expertise gined from over 50 yers experiene of designing nd mnufturing ontrol devies for industril, mrine nd hzrdous re pplitions. These swithes re onstruted with either robust luminium or stinless steel enlosure. The luminium sting is blk nodised nd supplied with 316 stinless steel overs. The stinless steel se is nturl finish. Covers re gsketted nd seled to hieve n environmentl sel to IP66 & IP67 stndrds. The internls utilise unique mehnism designed by the engineers t PYROPRESS to produe wide rnge, low swithing differentil nd exellent repetbility. This ombined with vriety of miroswithes, mountings nd sensor options hs produed swith rnge suitble for ll wetherproof nd intrinsilly sfe pplitions. CALIBRATION The design fetures simple form of librtion djustment ginst sle plte. This llows users to either order units with speifi setting, or stok mid rnge setting nd then librte to suit the pplition. Clibrtion is performed on the opposite side of the swith to the eletril onnetions, nd n be set sfely with the swith supply live. On removl of the djustment over smll grub srew n be loosened llowing the djusting ring to be turned with smll Tommy br or Allen key. The setting is red from the entre of the red inditing ring ginst the librted sle plte. Clibrtion proedures for dul miroswithes nd djustble swithing differentil swithes re detiled on the operting nd mintenne instrutions supplied with eh swith.

6 TECHNICAL SPECIFICATION Swithse nd overs: 316 stinless steel swithse with 316 stinless steel overs or blk nodised luminium swithse nd 316 stinless steel overs. Optionl 304 stinless steel mounting brket. Miroswith: SPCO/SPDT. Options inlude single or twin swith ssemblies for simultneous or seprtely djustble set points, djustble swithing differentil, mnul reset nd noble metl ontts for use on intrinsilly sfe iruits. Miroswith rting Stndrd miroswith Adjustble dedbnd nd high Current DC swithing : V.AC : V.AC & 5 V.AC : 5 30 V.DC & V.DC : V.AC & DC : V.AC & DC Eletril Connetions: Srewed terminls diret onto miroswith, suitble for ble up to.5 mm. (Mnul reset miroswith is supplied with 6BA solder tgs). Eletril Conduit Entry: M0 x 1.5 stright entry. Adptors re vilble. Environmentl Protetion: Swithes hve been tested nd ertified by n externl test house to IP66 in ordne with BS EN 6059 : 199. In ddition further internl tests onfirm tht the swithse meets the requirements of IP67. Vibrtion nd shok prmeters: Swithes were subjeted to Lloyds Register Type Approvl System Test Speifition No.1 Cluse or 13 Vibrtion Test 1 or (refer to sles for ext speifitions) nd shok tested to BS EN : Temperture Limittions: Pressure, Vuum nd Differentil Pressure. Proess: Diphrgm tuted (unless otherwise stted) -30 to +100 C (Nitrile) or -0 to +150 C (Viton). Piston tuted -30 to +100 C (Nitrile), or -0 to +150 C (Viton) or -50 to +150 C (PTFE) -30 to 5 C (EPDM) Ambient: -5 to +80 Deg.C. Storge: -5 to +80 C. (For temp, level nd flow refer to speifi pges). Certifition: All swithes re CE ertified nd mrked in ordne with the following EU diretives. Industril : 014/35/EU (Low Voltge Diretive). Exi: ATEX 014/34/EU oded CE Ex II1G Exi IIC. CAT 1 (Zone 0) res. Speil onditions for sfe use. (Ctegory 1, Zone 0) Aluminium my only be used when the ignition hzrdous ssessment shows tht there is no risk of ignition from inendive, impt or brsion sprks. ABOUT PYROPRESS Our produts re designed to work in demnding nd hzrdous environments whih require fst nd ost effetive solutions in instrumenttion nd ontrol. Pyropress ontrol sensors provide sfe nd relible eletril swithing of lrm or ontrol iruits in response to hnges in temperture, pressure, differentil pressure,vuum, fluid, flow nd level onditions.
