Float Switch Dealers

Cable Float Switch is a control device for automatic On/Off  pumps, motor and magnetic valves. It is also an alarm device at certain pre-determined surface levels. It is suitable for use in non-flammable liquids at 250 volts. In dangerous environments (e.g. wells and pumping stations) we recommend 24 V voltage. In potentially explosive atmospheres (e.g. oil tanks) the Switch can be used in conjunction with (Ex) I-isolator switch units. Due to its large float casing the float Switch has a buoyancy which guarantees smooth, trouble-free operation under all conditions. The switch has double chamber and a final remoulding finish to make it absolutely hermetic. Installation:Cable Float Switch is simply placed in the liquid so that the float follows the movement of the surface. The switching height differential is adjusted by moving the weight along the cable. The differential is minimum, when weight is nearest to the float. If the viscosity of the liquid is high, we recommend an extra weight on the cable.

Side mounted float type level switch for low oil level measurement equivalent to sika german   Principle of Operation This instrument has a side mounted screwed process connection of 3/4” BSP (m). Float is fabricated in accordance with the service or fluid. When the level rises above the actuation point. The float buoys up along with the level rise and actuates the magnetic switch which is kept inside the stem. The closure of the switch can operate a contactor or relay to indicate the level rise or decrease.     Material specification Available in SS and Brass

Magnetic float switch A float sensor or float switch is an instrument to measure the level of liquid in a container. This is widely used in automatic water level control in an overhead tank. Float Sensors find its applications in domestic water tanks. When water reaches certain level in the solenoid of the senor, it generates a signal, which is then interpreted to measurable quantity of liquid.

Hermetically sealed glass encapsulated reed switch. Option of remote or integral control unit. Option of remote counter & totaliser for volume application. Option of Intrinsically safe switch with zener barrier. Max. Temp. – 150˚ C Max. Pressure – 25 Kg/cm² Special Features : Intrinsically safe to Ex ib Gr IIA- IIB T6 (with zener barrier 24 VDC/110 mA)

Model MLS - 04 / MLS -16 magnetic level switches work on the principle of magnetic repulsion and therefore they are glandless and leak proof instruments. A permanent magnet fitted in the tail piece of the float repels another magnet inside the switch housing which in turn operates an SPDT microswitch. Microswitch contacts can be utilized for initiating audio-visual signals or pump control. SALIENT FEATURES : As our switches work on magnetic repulsion principle, they are glandless and leak proof. No power consumption. Internal assembly wirings are teflon insulated. Internal switch assembly bracket is of cast aluminium. Practically no maintenance is required except periodic cleaning. Suitable for 2.5" (65 mm) NB nozzle mounting, (for 63 mm dia float) and 2 " (51 MM) NB nozzle for 48 mm dia float. Maximum working temperature 250°C. (Process Temperature) Contact ratings of MICROSWITCH 5 AMPS at 230 VAC Resistive. Also available with Microswitich having current rating 10 A at 230 VAC Resistive. No of contacts : 1 change over as standard. Optional - 2 change over For high temperature upto 350°C (Process temperature) 1 number SPDT Reed switch with current rating 100 VA, max. switching current 5 Amps, max, switching voltage 230 VAC / 200 VDC Specific Gravity : Down to 0.75 CAUTION : Level Switches should not be used for direct starting / stopping of pumps. An external relay or contractor must always be used with the level switch. MLS-04/MLS-16 side mounted level switches must always be mounted horizontally with outgoing cable entry facing downwards. In case of high temperature Model MLS-04-92 HT/MLS-16-92HT and Low Temperature Models SMT-04-F82 and SMT-04-F92 arc suppressors/current limiting bias resistor must be provided depending on the load viz inductive or lamp load etc. to reduce the deteriorating effect of contacts due to surge voltages and high in-rush current TECHNICAL SPECIFICATION : Model (MLS-04-F82) or (MLS-04-F92S) side mounted magnetic Level Switch.Process connection- 82 or 92mm square flange with 4 bolt holes of 10/14mm dia on 82 or 92mm PCD respectively. Matenal of construction of flange, brackets, fulcrum screws, body and cover-SS 304(For wetted parts in SS 316 please denote by 16 instead of 04 in the Model).

Differential between make and break-10mm approximately.Maximum working pressure 10 kg/sq.cm and temperature 250 deg C.Specific gravity down to 0.7.Cable entry neoprene gromet. Supplied with 1.5 Metre long 3-core PVC Cable. NB : In case of Model MLS-04-F92 flange size shall be 120 mm dia round flange with 4 bolt holes of 14 mm on 92 PCD. .  

We have various type of level switches. Depending on the process medium (clear liquids, viscous medium, medium at high temperature, highly corrosive medium, medium containing solid or, magnetic particles etc.) and application details (cryogenic application, tank with agitator, explosive area), we advise the suitable type of level switch. For clear liquids we have magnetic float operated level switches, pp cable float level switches, conductivity level switches, vibrating fork level switches etc. For dry and free flowing powder, granules, pallets etc we have rotating paddle level switches, vibrating fork level switches, boot diaphragm level switches etc. For slurries and sticky mediums we have rf admittance level switch, low capacitance level switch, lbfs, lffs etc. For explosive areas, we have exproof level switches also.

Cable Float Switch is mainly used for water, sewage water, Effluent water, Slurries, sticky or viscous liquids. Cable Float Switch has the technical advantages as the devices are for intensive uses and has a 110° working angle. Highlights : Specifically used for the automatic working of small pumps and cellar emptying pumps Efficient performance Sturdy construction
