SMARTsaa offers variety of Safety Switches for use on Conveyors. We manufacture and export Safety Switches like Pull Cord switch, Belt Sway Switch, Heavy Duty Limit Switch, Electronic Speed Switch, Belt Loading Monitor, Chute Jam Detector, Belt Damage Detector, Boot Level Detector, De-Interlocking Switch for protection and monitoring of conveyer belt and other machinery used in material handling plants.
PULL CORD SWITCH
It is a rope operated emergency switch. It is provided with operating handle fitted with spring steel rings at both ends for fixing the rope. Pull cord switch is mounted on the walkway side of conveyer belt, preferably at about every 30 meters length. Rope is tied to the end rings of the handle. When the rope is pulled from any side, the switch is operated.
BELT- SWAY SWITCH
This switch allows smooth running of the conveyer and protects it from damages by over swaying which can occur due to uneven loading of material, worn out idler roller bearings etc. The belt sway is generally mounted on both sides and near the edge of conveyer belt. A small gap is provided between contact roller and the belt edge to allow normal running of the belt with acceptable tolerance. When swaying exceeds normal limit, the belt edge pushes the contact roller, which drives the switch and operates the contacts.
HEAVY DUTY LIMIT SWITCH
SMARTsaa offers Heavy Duty Limit Switch for use on heavy machines. These switches give position feedback by operation of contact.
ELECTRONIC SPEED SWITCH
This switch is used to monitor speed of conveyers, crushers, rolling mills, agitators, mixers, stirrers, screw conveyers and other industrial machinery. The device 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. Speed range is to be selected considering normal running speed of the equipment and desired trip speed.
BELT LOADING MONITOR Series BLM:
Simple and robust device to detect the loading of material on he belt conveyor. It consist of roller assembly which is to be installed below the belt. Due to loading on the belt the roller makes contact with the belt and pushes the roller down actuating a switch. Contacts are used in control circuit for interlocking.
CHUTE JAM DETECTOR:
Various models are offered to detect chute jamming. Following are few models.
1.Chute Jam / Block Switch: RF Admittance Disc Probe
2. Chute Jam / Block switch: RF Admittance Rod Probe
3. Chute Jam / Block switch: RF Admittance Rope Probe
4. Chute Jam / Block switch: Tilt Probe
DAMAGE BELT DETECTOR
Belt damage detector detects and give early warning of belt damage. Damaged belt detector is to be mounted in pairs, positioned on either side of the belt. The units are connected by two spans of special PVC coated cable. One end of the cable mounts to a support bracket and other end is connected to a spring loaded ball located in DBD unit. The switch gets actuated when an object or broken belt sweeps away one or both cables pulling spring loaded ball out of socket.
BOOT LEVEL DETECTOR Series
Designed to sense material in a bin of bucket elevator. It gives warning when buckets are running empty. It can also be used to detect spillage level in bucket elevator.

SMARTsaa offers Conveyor Zero Speed Switch for detection of Zero Speed, Under Speed, Over Speed of conveyor. It also gives digital speed indication of conveyor speed.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. Conveyor Zero Speed Switch 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 and 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.

SMARTsaa has developed Damaged Belt Detector for early detection of Belt Damage of conveyors used in bulk material handling.
Generally two types of damages are observed:
1. Damages Occurred Due To Usage:
Damage of belt due to excessive usages, heavy loads, wearing and tearing of belt edges, poor vulcanizing of joints, peeling of steel cord, peeling of rubber portion of the belt etc.
2. Damage due to unhealthy working condition:
Cutting of belt due to locking of sharp object at discharge chute. As the belt is moving, the sharp metal piece cuts the belt longitudinally.
To protect conveyor belt against above damage, SMARTsaa recommend two types of protective devices.
DAMAGED BELT DETECTOR: ROPE TYPE: DBD R
This detector will protect belt against damage happened due to usages. It consists of pair of switches. The steel cord rope which are to be installed below the belt in a gap of approximately 500 Meters. The rope, one end of which is fixed with the end clamp, other end is provided with steel ball. The rope is fixed below the belt by keeping gap approx. 50 mm. The ball is held in catch. The switch lever gets pressed when the ball is fixed in catch.
When belt gets damaged sue to excessive use, its cord starts coming out, the rubber starts peeling off. The rubber or steel cord will stars peeling off and hits the rope. The ball comes off the catch and switch gets operated. The contacts are interlocked in circuit and the operator gets early warning.
One additional pair of DBD R can also be installed just after the return idler on return path to detect the belt damage of top belt surface.

SMARTsaa has developed Damaged Belt Detector for early detection of Belt Damage of conveyors used in bulk material handling.
Generally two types of damages are observed:
1. Damages Occurred Due To Usage:
Damage of belt due to excessive usages, heavy loads, wearing and tearing of belt edges, poor vulcanizing of joints, peeling of steel cord, peeling of rubber portion of the belt etc.
2. Damage due to unhealthy working condition:
Cutting of belt due to locking of sharp object at discharge chute. As the belt is moving, the sharp metal piece cuts the belt longitudinally.
To protect conveyor belt against above damage, SMARTsaa recommend two types of protective devices.
DAMAGED BELT DETECTOR: ROPE TYPE: DBD R
This detector will protect belt against damage happened due to usages. It consists of pair of switches. The steel cord rope which are to be installed below the belt in a gap of approximately 500 Meters. The rope, one end of which is fixed with the end clamp, other end is provided with steel ball. The rope is fixed below the belt by keeping gap approx. 50 mm. The ball is held in catch. The switch lever gets pressed when the ball is fixed in catch.
When belt gets damaged sue to excessive use, its cord starts coming out, the rubber starts peeling off. The rubber or steel cord will stars peeling off and hits the rope. The ball comes off the catch and switch gets operated. The contacts are interlocked in circuit and the operator gets early warning.
One additional pair of DBD R can also be installed just after the return idler on return path to detect the belt damage of top belt surface.
DAMAGED BELT DETECTOR: INFRARED TYPE: DBD I
This detector is designed to detect belt damage due to unhealthy condition. When belt gets cut longitudinally, the carried material like coal or iron ore starts falling through the belt cut.
The DBD R consist of infrared light curtain detector and controller. The sensors forms invisible curtain of invisible light. The curtain is installed below the carrying side of belt. The location is generally after 20-30 Meters just after the discharge chute. The curtain gets disturbed due to falling of material through the cut slot of belt. The signal is triggered when piece of carried material passes through light curtain.
