Mine hydrological substation, intrinsically safe hydrological substation, explosion-proof hydrological substation, dedicated for metallurgical mines
Hydrological substation, coal mine dedicated hydrological substation< br/> The mining intrinsically safe hydrological substation is a monitoring equipment that automatically measures and records water pressure (water level) and water temperature. The substation processes the frequency signals collected by the mining intrinsically safe pressure and temperature sensors through integrated circuits and converts them into digital signals that are displayed on the substation display screen and can be transmitted to the ground host computer through the interface for related data processing. At the same time, the parameters of the underground substation can be set through the surface host computer.
Technical parameters

, Signal control
The pressure sensor (~ should not be less than when it outputs high level (the output current should not be greater than when it outputs low level). Both its positive and negative pulse widths should not be less than
Temperature sensor (~ When outputting high level, it should not be less than (the output current should not be greater than when outputting low level). Its positive pulse and negative pulse width should not be less than
. The analog input processing error should not be greater than.
. Substation and modem The signal transmission should meet the following requirements
Transmission mode (master-slave, half-duplex, bipolar)
Transmission rate
Peak working voltage of communication signal
Sub-station electronic technology , computer technology and data communication technology are integrated. It has the characteristics of high measurement accuracy, strong real-time performance, stable operation and high degree of automation. It is small in size, light in weight, easy to install, and can automatically measure water pressure under unattended conditions for a long time. (water level) and water temperature are monitored.
