ThinPave™ 5500

Overlay Nuclear Density Gauge

Developed by the original inventor of thin-layer nuclear gauge technology, the 5500 is the only gauge that reliably measures pavement overlays from 0.5 to 4 inches (12.5–100 mm) thick.

• Ultra-thin layer accuracy in the top 0.5" (12.5 mm) of asphalt overlays
• Smaller overall footprint reduces surface contact for more consistent readings
• Fully enclosed, closed-source assembly — no base plate opening or source-cavity cleaning
• Stable, repeatable source indexing via an index/guide tube
• On-screen layer density with fast file transfer via the MyGauge App or USB (.CSV)
• Optional NukeTrack™ gauge tracking system

SIStec® SS200

Digital Clamp-On Pipe Density Gauge

An advanced, extremely stable digital density gauge with an onboard computer that integrates solids mass flow and total solids mass throughput measurements directly on the pipeline.

• Narrow beam geometry — a collimated gamma beam paired with a collimated NaI scintillation crystal eliminates Compton-scattering errors through the pipe and slurry
• Deadtime correction held to ±10 nanoseconds across the operating temperature range
• Automatic decay compensation recalculates the correction factor daily against the last calibration
• Gain stabilisation continuously compares count rate to a statistical model for automatic detector gain control
• Double-encapsulated Cs-137 or Co-60 source in an IP65 lead-filled shielded holder with rotary shutter
• Two isolated 4–20 mA outputs for SG, per cent solids & mass flow, plus a pulse-per-tonne mass flow integrator
• Modbus RTU, Profibus DP, DeviceNet & HART comms options; RS422 link up to 1000 m from the detector
