- No fault by mechanical reasons
- Can control digital signals (up to 80 points)
- Reliable and durable and simple in structure
- Pass EMI and EMC tests
Actuation and pneumatic equipment
- All types of cargo transportation
- LDP, LNG transport, PCTC
Structure and principle of operation of the system
The WIA-2000 includes a main alarm board, a repeating alarm board, an isolater, an external alarm device, and water level alarm sensors (electrolyzed, pressure, floats) installed in the cargo cellar or regulatory positions. When the appearance of water reaches the monitoring point of the level signaling contactes installed in the cavernous tunnels or other areas > Electrical signals are transmitted to the main control cabinet and the control cabinet activates the alarm and the alarm signal is given to the outside
