Analox SDA Rate of Change (ROC) 饱和潜水变化率分析仪

产品概述

The gas monitor reads results from a state-of-the-art, long-life digital electrochemical sensor. These results are shown on a full colour display.

The SDA ROC is used on some of the world's most advanced diving systems including a new build vessel for the BP Exploration Shah Deniz II project in the Caspian Sea.

安全重要性

To ensure diver safety it is essential to monitor and control the rate of change (ROC) of pressure to avoid hazardous rates of decompression. If the ROC is too high there is an increased risk of divers suffering the bends.

工作原理

The monitor provides alarms that are based not on the depth level but on the rate at which the depth is changing.

The SDA ROC monitors the pressure of an occupied dive chamber and triggers an alarm if the rate of change is too high. It does this by sampling readings from a depth sensor and applying an algorithm to smooth the effects of any sudden changes. The SDA uses the readings to calculate the ROC value which it then compares against its pre-set alarm thresholds.
