non-intrusive ultrasonic sensors for corrosion/erosion monitoring

Metal Samples along with Sensor Networks Inc., offers the smartPIMS® Datalogger non-intrusive ultrasonic corrosion/erosion monitoring system which is equipped with an onboard battery and memory that can
store up to 3,000 thickness readings.

It takes measurements at any user-defined time interval, storing them for manual offload to a tablet or PC via an RS-485 cable. The smartPIMS® Datalogger is used for applications where frequent measurements are required, but wireless infrastructure is not available or not permitted.

monitor corrosion rate
resolution to 0.001” (0.025mm) • high-risk areas • historically problematic locations
monitor “low spots”
post-NDE screening of pits to monitor re-maining thickness • measures down to 0.040” (1.02mm)
replace/augment intrusive methods
validation of coupons, ER probes, etc.
reduce costs
reduce scaffolding and insulation removal/refitting for internal corrosion monitoring • more accurate/reliable data improving operations

  • Operates on battery (2 years at 1 reading/day).
  • Stores 3000 readings (each w/ time, date, waveform).
  • Connects via Modbus (RS-485) to tablet/PC.
  • Offloads data to dataPIMS software which can export to an XML/CSV file and/or upload to web PIMS via Internet connection.
  • Offers 16 single- or 8 dual-element UT probe channels.
  • Transducers maintain 1 mil (0.001” / 0.025mm) resolution and 0.040” (1mm) minimum wall thickness.
  • Transducers withstand -22°F (-30°C ) to 932°F (500°C).
  • Sensors install buried or above-ground, temporarily or permanently.
  • ATEX, IECEx, UL/CSA and Japanese hazardous-area certifications.
