Two level deviation switch XTBP-20 belt deviation detector Two level deviation switch XTBP-20 belt deviation detector Application XTBP-20 Two level deviation switch can be widely used in various belt transportation machinery in industries such as metallurgy, coal, cement, mining, power, and grain. It is a detection device for safety protection and automation control of material conveying systems. Features: Cast aluminum shell structure, sturdy switch structure, high impact resistance, and durability· Second stage detection alarm. It is possible to alarm and control the deviation of the belt at the first level (light) and second level (heavy) separately· The switch is equipped with two sets of normally open and normally closed contacts, which can be used to stop the belt conveyor and give an alarm simultaneously. Technical parameters · Contact capacity: AC250V, 5A (inductive load)· Detection angle: The first level deviation detection action is 20 °, and the second level deviation detection action is 35 °· Environmental temperature: -20 ℃~60 ℃· Protection level: IP67< The classification of deviation switches includes ordinary type, wiring chamber type, and address coding type. The ordinary type refers to the two-stage deviation switch mentioned above; The wiring chamber type deviation switch is equipped with a waterproof wiring chamber on the basis of the ordinary type deviation switch. The on-site control cable can be directly connected to the wiring chamber to prevent faults caused by moisture and virtual connection of cable joints. The address encoding type deviation switch integrates XLline fieldbus technology on the basis of ordinary deviation switches, achieving address encoding function. Suitable for remote monitoring of the operation of long belt conveyors as on-site equipment, it solves the inconvenience caused by workers searching for fault points. The address encoded two-level deviation switch is connected to the comprehensive protection device (gateway) through XLline fieldbus, supporting up to 128 addresses, and multiple switches can be used simultaneously at the same address. Its main feature is that it only requires a two core cable to complete data transmission simultaneously without the need for power supply. XLline fieldbus can finally achieve flexible connection with major manufacturers' PLCs and computer interfaces< br/>
