● scope of application
Swj-iii the intelligent water level difference monitor is an intelligent comprehensive monitoring instrument with single chip microcomputer as the core to process multi-channel input signals and display multi parameters. It cooperates with the water level sensor to form a complete water level monitoring system of the power station, which can realize centralized online monitoring of the upstream and downstream water level of the power station, the water level of the trash rack, the water level before and after the gate and the corresponding water level difference, and complete the functions of digital display of parameters, out of limit alarm display and signal output. It can also be used with static pressure water level transmitter and liquid level transmitter with standard signal output.
● functional features
The working water level of the power station, the water level before and after the upstream and downstream grids and the water level difference of the gross water head are monitored on line.
Two level alarm display and output, and the alarm value can be set digitally.
Use panel keys to set the zero point and range of each channel, which can be modified online; It has the function of analog output, that is, it outputs the standard DC4 ~ 20mA signal corresponding to the upstream and downstream water level and water level difference range at the same time, and can provide five channel signal output at most (equipped according to the user's requirements).
The working power supply of the transmitter can be DC24V (equipped according to the user's requirements).
With parameter power-off protection function; Automatic zero calibration and full scale; It has self inspection function, self reset function and information prompt.
