Explosion proof two-stage deviation switch ST29-BKPT1-10-45 Explosion proof two-stage deviation switch ST29-BKPT1-10-45 Explosion proof two-stage deviation switch ST29-BKPT1-10-45ST29-BKPT1-10-45 Explosion proof two-stage deviation switch Environmental temperature: -40 ℃ to+60 ℃. Relative humidity: not more than 90%. Atmospheric pressure: 80-110kPa. Altitude: not exceeding 2000M. Service life: 10000 switch actions Insulation voltage: AC1000V Test for 1 minute ST29-BKPT1-10-45 Working principle and structural features: This series of explosion-proof deviation switches has a two pole action function. The first level action is used for alarm, and the second level action is used for automatic shutdown. When the tape machine is running, when the tape deviates and comes into contact with the vertical roller of this switch, the vertical roller rotates. If the deviation continues to increase, the squeezing vertical roller will shift in the direction shown in the diagram. When the deflection angle of the vertical roller exceeds 12 °, the first level switch acts and outputs an alarm signal. When the deflection angle of the vertical roller exceeds 30 °, the secondary switch will act and output (shutdown signal). The first level switch signal is used for alarm. If this signal is connected to the running adjustment device, it can achieve automatic adjustment of running deviation without stopping the machine. The second level switch signal is used for shutdown. Connect this signal to the control circuit to achieve automatic shutdown under severe deviation< After troubleshooting, when the tape leaves the vertical roller and operates normally, the vertical roller can automatically reset. In order to adapt to long-term use under outdoor conditions, this product is sealed as a whole, and the internal metal parts are galvanized and purified. The external parts, except for the shell, are coated with multiple layers of bright chrome. The shell is made of aluminum, and the surface is treated with electrostatic spraying technology, making it suitable for use in harsh environments.
