Conveyor Zero Speed Switch

SMARTsaa is leading manufacturer and exporter of Conveyor Zero Speed Switches Series ESM to monitor speed of conveyers, crushers, rolling mills, agitators, mixers, stirrers, screw conveyers bucket elevators 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. Operating Principle of Conveyor Zero Speed Switch: Speed sensor (Inductive Proximity Switch) 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. Standard contact rating is 5 Amp resistive at 230 V AC. 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. Speed range is to be selected considering normal running speed of the equipment and desired trip speed. Following models are available " ESM 1 W: Conveyor Zero Speed Switch for under speed monitoring, Field Mounting ESM 2 W: Conveyor Zero Speed Switch with digital display, Field Mounting ESM 4 W: Conveyor Zero Speed Switch for over speed monitoring, Field Mounting ESM 1 F: Conveyor Zero Speed Switch for under speed monitoring, Flame proof Enclosure ESM 1 D: Conveyor Zero Speed Switch with Digital display Front Panel Mounting ESM 5 D: Speed Indicator (Tachometer) Front panel mounting Digital display models provide more features like field adjustable scaling factor, keypad setting, two point contact operation etc. Models with 4-20 mA retransmission output is also available. Various other options are available. Please visit website to download catalogue.
