Pulse Controller is a pulse jet bag filter control device in cleaning system, its output signal to control pulse jet valve, blow compressed air bag sequential cleaning, so dust remains in the design within a predetermined range, in order to protect the processing power and dust collecting effect.
1. Controller outputs an electrical signal duration, called pulse width.
2. Controller output time interval between the two signals, called pulse interval.
3. The control device outputs an electric signal to complete a cycle, the time required for the pulse cycle is called.
Features:
1. Chassis: exquisite style PC works transparently bare chassis, with the appearance of new, sealed, dust-proof effect, to meet the modern international trends.
2. Movement: using chip technology to control the pulse output, pulse width, pulse interval and the number of output gates can be arbitrarily set according to the desired site, the realization of intelligent control.
3. Power supply: imported power components, thus ensuring the reliability of the machine, in harsh mining conditions of long-term stability.
4. Differential pressure control: can be connected with the second-tier passive differential pressure transmitter ,4-20mA standard current signal to the dust resistance remains within the set range, to ensure that in addition to the hubbub of the economy.
5. Wiring: Convenient and flexible plug-in terminals.
