DSP Subsea PIG Detector

PIG detection made easy and reliable

The ClampOn DSP PIG Detector controls and monitors when the PIG is passing the point of installation. Providing reliable information about the passage of the PIG increases pipeline integrity and produces cost savings.
Subsea Sand Particle Monitor

How it works

The ClampOn subsea sensors are designed to meet these requirements:

  • Designed for a service life of more than 25 years
  • Independent redundant electronics
  • Independent high and atmosphere pressure chambers
  • Electron beam (EB) welding of the chamber against external pressure (no rubber or mechanical seals)
  • Glass-metal penetrator as a barrier between high and atmosphere pressure chambers
  • Outstanding sensitivity, repeatability, accuracy and signal/noise ratio thanks to Digital Signal Processing (DSP-06)

Advantages

The ClampOn DSP Pig Detector, available in topside and subsea versions, is a more compact and user-friendly unit than other instruments on the market. It is easier to install in the field and easier to move to other locations.

DSP involves complete digitalization of the system and the elimination of analogue filters. This technology is increasingly used in a wide range of “smart electronic devices” as it provides sufficient capacity to perform advanced signal-processing tasks in real time. Such devices include medical diagnostic instruments, radar and sonar systems and mobile phones. ClampOn is the only manufacturer of pig detection systems to use DSP, which enables the sensor to operate in several frequency ranges simultaneously, eliminating the danger of the detector being triggered by noise sources other than pigs.

Integration

All our instruments are equipped with both digital and analogue interface, and comply with all common protocols. Our instruments can easily be integrated into any existing or new control system. A computer with our software is often used in-between our instruments and the control system. The computer will be used for sand calculation by using the RAW data from our sand detectors and flow data from third party systems, then output calculated sand rate to the control system. All recorded data will also be stored for analyzing and calibration purposes. We always recommend using the digital interface due to following benefits:

  • Two way communication enabling instrument software update and configuration
  • Full signal range resolution
  • All sensor data can be transmitted
  • No signal loss
