1 Water level control

2 Dryden Aqua Ltd | Butlerfield | Bonnyrigg | Edinburgh EH19 3 JQ | Tel 018758 22222 Fax 018758 22229 www.DrydenAqua.com 2 designs of float switches are available Industrial heavy duty Domestic or economy

3 Water level control Dryden Aqua Ltd | Butlerfield | Bonnyrigg | Edinburgh EH19 3 JQ | Tel 018758 22222 Fax 018758 22229 www.DrydenAqua.com There are two types of industrial float switch Standard switch which is rated up to 13 amps Intrinsically safe float switch will only take a very low voltage control signal Both float switches look identical except for the marking on the base, the ATEX Intrinsically Safe switch will be stamped on the base with the IS Industrial float switch Industrial float switch ATEX approved IS

4 Atex approved Water level control Dryden Aqua Ltd | Butlerfield | Bonnyrigg | Edinburgh EH19 3 JQ | Tel 018758 22222 Fax 018758 22229 www.DrydenAqua.com Atex float Max Input Parameters: Ui = 30V, Ii=100mA 8v, 8mA dc minimum contact rating Type Atex ( Certificate SIRA 04ATEX2187) may be used in zones 1 and 2 Temperature range –20°C to +70C and should not be used outside this range Max. submerged depth 20 metres Industrial float switch ATEX approved IS Chemical resistance

5 Water level control Dryden Aqua Ltd | Butlerfield | Bonnyrigg | Edinburgh EH19 3 JQ | Tel 018758 22222 Fax 018758 22229 www.DrydenAqua.com Standard switch which is rated up to 240v 15 amps non inductive, 240v 10 amps inductive Maximum size of electrical motor that may be switched is 1.3 hp, 230 v, 50 hz Maximum water depth is 20m You may switch the power via the float switch, but the best and safest arrangement is to use a low voltage such as 12 to 24v ac or dc through the switch, and use a relay to switch the pump on / off. By this means large electrical motors / pumps may be controlled Industrial float switch Standard Chemical resistance

6 Water level control Dryden Aqua Ltd | Butlerfield | Bonnyrigg | Edinburgh EH19 3 JQ | Tel 018758 22222 Fax 018758 22229 www.DrydenAqua.com Economy switch has the same specification as the standard switch Rated up to 240v 15 amps non inductive, 240v 10 amps inductive Maximum size of electrical motor that may be switched is 1.3 hp, 230 v, 50 hz Maximum water depth is 20m You may switch the power via the float switch, but the best and safest arrangement is to use a low voltage such as 12 to 24v ac or dc through the switch, and use a relay to switch the pump on / off. By this means large electrical motors / pumps may be controlled Economy float switch Chemical resistance Polypropylene casing and PVC cable High level of chemical resistance Suitable for most water applications

7 How do they work Dryden Aqua Ltd | Butlerfield | Bonnyrigg | Edinburgh EH19 3 JQ | Tel 018758 22222 Fax 018758 22229 www.DrydenAqua.com 2 designs of float switches are available Both float switch work in the same way Standard switch has integral weight, economy switch has a separate weight The weight acts as the pivot point for the switch When the switch tilts to the angle shown an electrical circuit is made or broken

8 How do they work, electrically Dryden Aqua Ltd | Butlerfield | Bonnyrigg | Edinburgh EH19 3 JQ | Tel 018758 22222 Fax 018758 22229 www.DrydenAqua.com The economy and standard floats have the same wiring The switches have three wires, brown, black & blue The Brown wire is the common By connection of Brown & Black, or Brown & Blue wires the electrical circuit may be made or broken, you therefore have the option of normally open or closed circuit on filling or emptying

9 Applications Dryden Aqua Ltd | Butlerfield | Bonnyrigg | Edinburgh EH19 3 JQ | Tel 018758 22222 Fax 018758 22229 www.DrydenAqua.com For ATXE application or potentially explosive environments contact Dryden Aqua The standard and economy switches may be used for all aquatic environments Some examples Tanks Lagoons Basement protection from flooding River and lake level Water treatment system Pumping stations Many industrial applications Dryden Aqua float switches are used when you require a simple yet robust means of controlling water levels
