Woodward 8446-1019 Level transmitter

8446-1019 frequency constant pressure water supply control system consists of PLC controller, touch screen monitor, frequency governor, pressure transmitter, water level transmitter, AC contactor and other electronic control equipment, as well as three pumps (the number of pumps can be set according to the needs of the pumps) and a small flow pumps, etc., as shown in Figure 1. Installed in the water supply system on the total outlet pipe pressure transmitter detection of water pressure, installed in the reservoir level transmitter


8446-1019 with analogue input detection module, detection of pressure transmitter and level transmitter output 4-20mA signal, the detected pressure signal and the set pressure signal after PID operation, by controlling the output frequency of the frequency converter to adjust the motor speed, to maintain a constant water supply pressure, which constitutes the set pressure as the basis for the pressure of the closed-loop system.

8446-1019 can automatically detect the water level signal of the pool and compare it with the set low limit of water level, and output the low water level alarm signal or stop the machine directly. Touch screen monitor can display the power supply voltage, current, frequency converter output frequency, the actual water supply pressure and set the water supply pressure and the working status of each pump and other information; you can modify the set water supply pressure and control the operation of the pump through the touch screen online. The system is also equipped with a variety of protection functions, especially strong electrical logic hardware interlock function, thus ensuring normal water supply, and can be unattended.
