Belt Conveyor Protection Device With Sensors
1. Purpose
It is suitable for the environment with gas and coal dust explosion in coal mine. It is used for electrical control, monitoring and comprehensive protection of belt conveyor and other equipment in coal mine. It can also be used in harsh ground environment, as the host of electrical equipment in metallurgical, chemical, building materials, electric power, transportation, grain and other industries.
2.Characteristics
1.It has the functions of language warning and language accident alarm. The language alarm can not only report the nature of the fault, but also the number of the belt conveyor;
2.It has working power supply AC127 and 220 V, which is convenient for users;
3.It has the same functions as similar products, such as remote control, local control, centralized control, etc.
4.It has the function of speed measurement and temperature measurement, and can directly display the temperature value and speed value;
5.There are few connecting wires between the function boards, which greatly reduces the wiring fault and makes the device operate more reliably.
3.Main technical parameters
1. Limit input voltage: AC127V or 36V, voltage fluctuation allowed: 75-110% Ue
2. Maximum open circuit output voltage of the safety: DC12V± 0.5v
3. Maximum short circuit current output of this ampere: DC40mA; Overcurrent protection setting value: 1.3a.
4. Internal permissible distributed capacitance of internal output: 0.1uF/Km
5. External permissible distributed inductance of intrinsically safe output: 0.1mhKm
6. Relay output contact capacity: AC250V/5A
7. External dimension of this device: 320mm×120mm×330mm, weight less than 15kg.
