Using the sectin This sectin helps yu make a lgical chice in selecting the best prduct fr a particular applicatin. It allws a user familiar with ur prduct line t lcate the exact page the prduct is listed n. Fr thse nt familiar with ur prducts, a lgical sequence is given t help the user pick the best prduct fr their need. By taking a few minutes t familiarise yurself with the catalgue rganisatin, yu will find it very easy t lcate the prduct / infrmatin yu need. 1. The cntents page lists the brad utline in which the catalgue is rganised, and will help the user familiar with prducts t select the page n which the prduct r ther useful infrmatin is listed. 2. Need Prduct Selectin help? Prduct selectin help will start with the Pictrial Index n Page 11, where the prducts are bradly classified. A brief descriptin f each prduct grup, a typical pht f the prduct within the grup and the page number n which it is listed are given. If the user is nt familiar with the prducts, a prduct selectin guide is prvided n pages 16 thrugh 20, where phts fr each prduct and imprtant specificatins are given t help determine and select the best prduct fr the applicatin. By evaluating and cmparing these parameters, a lgical selectin can be made. Turn t the page n which the prduct infrmatin fr the selected prduct is listed, fr : Capsule Cnstructin details Physical sizes Special features Ranges, hysterisis, electrical ratings etc. Ordering infrmatin Sme applicatins The rganisatin f each f these pages is demnstrated n pages 12 & 13, f the sectin Hw t use this sectin. In many cases, mre than ne prduct may wrk. Fr the mst cst effective slutin, cmpare prices and cnsider alternatives. Remember, the end cst includes initial prduct price, plus the installatin, plus the service. 3. Need the terminlgy explained? (see page 330) Turn t page 330 fr the definitins and terminlgy. This will help yu familiarise with the terms used thrughut the catalgue. 4. Need infrmatin n Accessries? (see page 322) Turn t page 322 fr infrmatin n imprtant accessries. These will give infrmatin n nly imprtant accessries, and infrmatin needed, when these are t be supplied with ur prducts. 5. Need selectin guidance? (see page 331) A lgical prcedure n page 331 will help yu t cnsider mst f the imprtant factrs when selecting a pressure switch. 6. Need ther prducts? (see page 332) Prducts ther than thse listed in this catalgue are referenced n these pages. Separate catalgues fr these prducts are available. 8

HOW TO USE this sectin Due t the variety in prduct types and their salient features, catalgue page frmats may vary. But generally the fllwing frmat is adhered t. Elements appearing n each page will be: 1. Prduct family / series - A prduct family / series will appear n the utside page crner, depending n the left / right hand page, and will be in large bld type. 2. Prduct sectin - will appear immediately fllwing the prduct family / series at tp f the page and will be in bld type. 3. Features - will appear next t prduct descriptin & will enlist nly the majr attributes. 4. Pressure capsule details - will shw the cnstructin f the pressure capsule and all it's internal parts. If the prcess / wrking medium is variable, the wetted parts will be mentined in italics. If the wetted parts are unique, the material f cnstructin (MOC) will be mentined alngside in brackets. Where the material f cnstructin is nt specified, it will vary and the ptins are t be selected by the user cnsidering the cmpatibility f the prcess / wrking medium. Mdificatins can be made t suit any particular medium, if the answer fr yur needs is nt in the standard MOC listed. Prducts fr which prcess / wrking medium is predefined, pressure capsule details are nt prvided (e.g as in case f cmparisn test pump). Pressure capsule details f accessries are nt given. 5. Installatin drawing - will shw the typical installatin dimensins f prducts as they exist in their standard frms. The dimensins are mentined in millimetres and als in inches t facilitate the user. The dimensins f accessries will have t be added t these t arrive at any particular general arrangement (GA) drawings. The 2 6 1 7 3 4 5 10 12

Installatin drawings f nly fast mving accessries are given. 6. Phts - will appear n the relevant tp f the page fr prducts. If there are munting variatins / styles, all the styles fr standard prducts will appear fr easy identificatin. Optins, if included in the phtgraph, are fr demnstratin nly, and are nt a part f the standard equipment. Fr accessries, the phts are nt given due t the sheer variety and range available. 7. Lg - will appear n right hand tp f page t identify the manufacturer. 8. Characteristics - Range tables and their relevant data, e.g the range cvered, the differentials and maximum wrking pressures will generally appear n the right hand page. Additinal technical details will als be mentined, wherever required, n the right hand side f the page. 9. Ordering guide - A guide as t hw t rder the particular series' variatins will appear n right hand bttm f the page. Only the variatins available within a particular prduct family / series will appear here. Any additinal accessries r mdificatins required fr the prduct need t be mentined in text by the user. 10. Sme applicatins - will appear at the bttm left f the page. This is fr easy understanding f the specific use f the switch. 11. Numerus cmbinatins are pssible when pressure switches are prvided with accessries like chemical seals, snubbers, remte seals, pipe munting brackets, cmbinatin f switches munted in a panel etc. Users are requested t prvide the details f accessries required in text / drawings, as separate identificatin cdes are prvided fr pressure switches fitted and supplied with accessries. 8 9 13 5

Switch Cnstructin The versatile cnstructin f FC series flameprf switches can be cnfigured t suit applicatins, by selecting the fllwing main subassemblies / cmpnents : a) The flameprf head FC 1, 2, 3 : Aluminium flameprf enclsure fr Gas grup IIA, IIB, IIC FC 4, 5, 6 : Grey Cast Irn enclsure fr Gas grup I fr mines FC 7, 8, 9 : Stainless Steel enclsure fr highly crrsive atmspheres (Gas grup IIC). The cable entries in these flameprf heads can be ffered in ne f the fllwing thread sizes, t suit apprpriate cable diameter : ½ NPT F ¾ NPT F M20 X 1.5 b) The electrical element (s) : Chice f electrical elements t suit end use are ffered, like : A1 : General purpse applicatins A2 : Hermetically sealed fr crrsive envirnments A3 : gld plated cntacts fr lw vltage applicatins A4 : DPDT cnfiguratin A5 : fr high DC ratings A6 : elements with adjustable deadband A7 : 2 SPDT switching elements It is pssible t have mre ptins f electrical elements nt published here, t suit individual end use. The deadband (r hysterisis / n-ff differential) f the switches will change with the change f the electrical element (s). The apprximate values fr each range (fr standard micrswitches ffered) are published in this catalgue c) The pressure capsule : T suit the setpints, the wrking media and the functin f the switch in the applicatin: High pressure ranges (typically frm 0.067 barg t 25 barg) Lw pressure ranges (typically frm 1.5 mbarg t 350 mbarg) High range Pressure difference (typically frm 0.1 barg t 25 barg) Lw range pressure difference (typically frm 1.5 mbarg t 350 mbarg) Vacuum (typically frm 760 mm Hg t atmspheric pressure) Hydraulic pressure ranges (typically frm 0.5 barg t 400 barg) The pressure capsule can be mdified t take high prf pressures [typically 100 bar fr high and lw pressure switches, r pressure difference switches (frm high pressure side)]. Several accessries like chemical seals, pipe munting brackets etc can be supplied with these switches t suit the media t be sensed. All f these are nt listed, thugh mst ppular nes can be fund n pages 322 thrugh 332. Please d get in tuch with us fr any f yur applicatins, nt addressed in this catalgue.
