What is residual pressure controller
The network-based residual pressure monitoring system consists of four parts, including residual pressure detector CS-Y03N (also known as residual
pressure sensor or differential pressure controller), residual pressure controller CS-Y04C, residual pressure monitor CS-Y04M, and pressure relief valve actuator.
The residual pressure controller can receive signals from the residual pressure detector and perform centralized processing to
control the electric actuator of the pressure relief valve, thereby controlling the opening and closing of the bypass pressure relief valve.
The residual pressure controller can provide centralized power supply to the residual pressure sensor CS-Y03N (residual pressure
detector) and the electric actuator (bypass relief valve control mechanism), and provide real-time feedback of on-site information to the residual pressure monitor CS-Y04M.
1、 Product features of residual pressure controller CS-Y04C
1. Monitor the status of the residual pressure detector and adjust the pressure relief valve in conjunction with the residual pressure detector;
2. Fire protection dual bus communication and power supply are used between the residual pressure detector, and only NHRVS-2 × 1.5 mm ² communication line is used;
3. The multifunctional button can query the total number, working status (running, alarm, fault), and pressure relief valve status of all residual pressure detectors in this circuit;
4. Chinese LCD display screen, compact product design, fully functional;
5. Each circuit can carry 256 residual voltage detectors.
