SMARTsaa Zero Speed Switch with Digital Display to monitor speed of conveyers, crushers, rolling mills, agitators, mixers, stirrers, screw conveyers, bucket elevators and other industrial machinery. The digital display indicates equipment speed as well as set speed accurately. The device also actuates relay contacts at preset speed. Using these contacts, desired control action such as zero speed protection / under speed protection / over speed protection can be achieved. SMARTsaa DZZZ can also be used to indicate linear speed of equipment in MPM / MPH by suitable entry of scaling factor. Scaling factor is also adjustable. Speed sensor is placed in close proximity of the rotating object. On this object, metallic plates are fixed. Sensor detects presence of metal objects which come within the range of their oscillating field giving rise to corresponding pulses. These pulses are fed to the control unit where they are compared with the standard pulses to sense the speed. Output is in the form of relay contact. In case of under speed – zero speed application built-in initial by-pass time delay is provided to allow the rotating machinery to attend the desired speed. If after this set time the motor does not attend the set speed, the relay is de-energized and the switch resets automatically when the desired speed is attained. Digital display models provide more features like field adjustable scaling factor, keypad setting, two point contact operation and Universal Speed Range etc. SPECIFICATIONS: SMARTsaa DZSS•Duty : Under Speed Monitoring with Digital Display•Control Supply : 110/230 VAC Please specify any one• Enclosure for control unit: Cast Al, IP 65, Field Mounting• Control O/P : 2 C/O Potential free Relay Contact• Speed Range : 5-5000 RPM • Speed setting : Key Pad• Contact rating : 5 Amp.

BrandSMARTsaa
SMARTsaa has developed entirely new range of Belt Misalignment Sensor for Bucket Elevator. These sensors find application on bucket elevator to detect misalignment of buckets. Bucket elevators have sidewalls, which a misaligned belt can rub against. Heat generated by this rubbing action can quickly reach a dangerous level, especially near pulleys where the belt side forces are the greatest.  The casing may get damaged due to rubbing of the misaligned belt to the side wall of bucket elevator.Extended range proximity sensors are mounted on the side of the casing. Two sensors are fitted, one on each side on the casing of bucket elevator on a location where bucket sway is maximum.In normal running condition the bucket is away from the sensing range of the sensor. But when swayed, the bucket face comes in the sensing range and the contact is actuated.As two sensors are used, one at each side at least one sensor, whenever side the bucket sways at least one sensor will actuate and, positive belt misalignment sensing is done. Two types are belt misalignment sensors are offered •Inductive Type : Having nominal sensing range of 50 mm ( effective 35 mm ) and 80 mm                ( effective 50 mm ) •Magnetic Type : Having sensing range of 50mmSalient Features: 1. No physical contact                 2. No wear and tear, hence long life. 3. Switches for use in hazardous locations are also available.4. High sensing range5. No effect of dust, water and mud hence reliable operationSpecification:•Supply: 10-30 V DC•O/P: PNP or NPN, NO + NC•Load current: 200 mA •Size:  Rectangular Block type with mounting bracket and gasket  •Object sensed:  Any Ferromagnetic minimum size 150 x 150 x 2 mm•Sensing Range: Up to 80 mm•Max operating frequency: 100 Hz•Operating Temp: 70 degree cent•Enclosure: ABS Plastic , IP 67Additional power supply working at 230 V AC and with latching circuit with local reset push button available.

SMARTsaa has developed Missing Bucket Detector for Bucket Elevator. These sensors find application on bucket elevator to detect missing buckets. As the bucket elevator speed is constant the time gap between two passing bucket is also constant. Extended range proximity sensors are mounted on the side of the casing. The bucket when passes in front of the sensor a pulse is generated. The sensor gives command to a pulse evaluation circuit. When the time between two passing buckets exceeds a control action is generated.Specification:Sensor: •Supply: 10-30 V DC•O/P: PNP or NPN, NO + NC •Load current: 200 mA •Size:  Rectangular Block type with mounting bracket and gasket  •Object sensed:  Any Ferromagnetic minimum size 150 x 150 x 2 mm•Sensing Range: Up to 80 mm•Max operating frequency: 100 Hz•Operating Temp: 70 degree cent•Enclosure: ABS Plastic, IP 67Control Unit:•Supply: 230 V AC•O/P:  2 C/O Relay Contact •Contact rating : 5 Amp resistive at 230 V AC•Enclosure: Cat Al , IP 65•With pulse gap adjustment potentiometer

SMARTsaa offers Heavy Duty Limit Switch for use on heavy machines. These switches give position feedback by operation of contact. The application include position sensing of crane, stacker reclaimer, loader etc. The robust design makes its use on heavy machinery.
These switches have been developed to meet the requirement of ‘Extra Heavy Duty’ service as found in cranes, in mining, foundries, steel plants etc. where limit switches have to withstand high electrical and mechanical wear. The roller limit switch is used on cranes, stackers and reclaimers to sense position end of travel etc.The heavy duty roller and actuation mechanism makes it immune for impact of these machinery. The bodies and covers are fabricated out of thick cast iron/ Al enclosures, which are resistant against corrosion and rough handling. 
Two types of actuation mechanism are offered 1) Stay put type where the switch remains in actuated position and same gets reset only when the lever is pushed back by operating mechanism.2. Spring Return Type where the roller regains its position when the operating mechanism goes away.
Following models are available “

Belt Sway Switch Series: BS offered by SMARTsaa are designed to stop the conveyor belt & to indicate the fault when the conveyor belt sways beyond limit. The switch allows smooth running of the conveyor & protects it from damages by over swaying. Over swaying can occur due to uneven loading of material, worn out idler roller bearings etc.
The switch is housed in dust & weatherproof cast aluminum enclosure with IP 65 grade of protection. Special corrosion free DMC enclosure is also developed for use in seashore, saline atmosphere. The SS sleeved contact roller fitted with pre lubricated sealed ball bearings. This assures smooth operation of the roller over a long period of time. Switch mechanism is of self reset type.  The enclosure is epoxy painted to withstand harsh climate.
Belt sway switches are to be mounted along the sides of the conveyor belt. Ideal gap between two switches is 30 Meters. Small clearance is kept between roller and belt edge to allow belt for some sway. When the belt sways it torches the roller and switch is actuated. The contacts are wired in interlocking circuit to trip the conveyor. The switch is normal action spring return type.
