Pop and Leak detection for PSV process safety valves

This device is designed to capture, and time stamp the PSV tag that has popped, as well as the potential subsequent failure to re-seat of the PSV, causing internal leakages. Before mounting on the PSV, the unit is assigned a tag that corresponds to a PSV to which it is clamped. The clamps used are a simple industry standard saddle straps. The device is approved Intrinsic safe by Presafe 20 ATEX 403841 / IECEx DNV 21.0105 and CE compliant tested by Nemko NEX388458.

CBM Predictor operates by continuously monitoring the immediate environmental noise, vibrations and other variables surrounding the PSV. When the monitored variables have breached the pre-set alert levels, the messages are sent via the Bluetooth to the cloud or to a specific application. The device can also be interrogated using a hand-held device used during operator walk-downs.

The measurements identify the pop, recording that the PSV has opened and is performing the safety function. The additional measurements identify the potential leakage, recording a possibility of failure to re-seat the PSV properly.

To eliminate potential false positive readings, the users have an option to set the sensitivity of both measurements in accordance with the immediate surrounding environment. The settings are simple and intuitive.

CBM Predictor also stores all the measured values, the user settings and the alert levels, together with the time stamp and the device tag associated with the PSV tag. The data stored can be uploaded to either a cloud, to the operator walk-down hand-held device, or to any dedicated application. To eliminate the data flooding, the messages that are communicate do not contain all the data, only the time stamp and the device tag of the PSV that caused the alert to be triggered. ​

With a battery life time of up to fifteen years, the device communicates over Bluetooth (BLE 5 and future BLE Mesh) to your preferred Cloud solutions and maintenance system.
