Alarm setting value

The Intrinsically Safe Type Vapour Pressure Monitoring system is intended for Cargo tank pressure monitoring.
This system consists of pressure sensor which has especially suited metallic diaphragm type (SUS 316L) especially suited for the low pressure to be measured and I.S barrier, pressure monitoring & alarm panel with isolation valve. The output signal which arise by vapour pressure at pressure sensor is transmitted to the pressure monitoring & alarm panel through I.S barrier in safety area and then the ullage space pressure is indicated on the pressure monitoring & alarm panel.
Especially, the display shall be classified into two types according to concentric type using the Multi-tank monitor and individual type using digital indicator.
