INSITE - Concrete Temperature and Strength Sensors

INSITE delivers critical concrete data so you can make better decisions. INSITE loggers record concrete temperature and calculate on site concrete strength using maturity. The concrete maturity method is a proven early age strength estimation technique (ASTM C 1074) that accounts for the effects of time and temperature on the strength development of in-place concrete.

Recommended array: GX2

Recommended array: GX1

Why use the GS9000 instead of a conventional single-channel GPR?

Cover more ground

Collect multiple parallel profiles in one pass instead of uilding a grid line by line.

See results during acquisition

View georeferenced radargrams and time-slice information in the field rather than waiting until the data is returned to the office.

Produce repeatable mapped data

Combine wheel-positioned GPR data with GNSS, project coordinates and survey linework.

Use one platform for two very different applications

Exchange GX1 and GX2 arrays without purchasing two complete cart platforms.

High-density 3D GPR mapping for SUE and utility investigations

The GX2 transforms the GS9000 into a high-density subsurface utility mapping system. Its 11-channel, low-frequency GPR array captures an 83 cm-wide swath in each pass, helping operators detect and map buried pipes, ducts, cables, voids and other subsurface features. Live georeferenced data lets SUE teams review coverage on site and produce accurate CAD, GIS and project-coordinate deliverables.

  • Utility corridor mapping
  • Detection of pipes, ducts and cables
  • Mapping non-conductive services that may not respond to electromagnetic locating
  • Congested service investigations
  • Road-crossing and easement surveys
  • Potential void and cavity investigation
  • Pre-excavation and design-stage surveys
  • Utility mapping to project or local coordinates

The SUE field workflow

1. Plan the survey

Load satellite imagery, CAD information, project coordinates or survey control.

2. Collect dense multichannel data

Survey an approximately 0.82 m-wide swath with 11 channels in each pass.

3. Review data live

Examine radargrams, georeferenced time slices and marked features while still on site.

4. Interpret and digitise

Add points, linework, tags, photographs and field observations.

5. Process and deliver

Merge survey areas, apply processing and export mapped information for the customer’s CAD, GIS or reporting workflow.

INSITE loggers are made for the world´s toughest construction projects. Providing critical temperature profile and strength information so the best decisions can be made at exactly the right time.

These rugged loggers are designed with redundant systems and high temperature components to ensure they survive in the hottest, harshest concrete environments.

INSITE strikes a perfect balance between wired and wireless technologies, resulting in increased reliability, global accessibility, and every-job affordability. When combined with intelligent cloud-based software, InSite puts the concrete data you need in the palm of your hand.

How INSITE works

INSITE loggers can run offline and be manually synchronised, or in real-time with continual connection to a Wireless Remote.

A single Base Station provides wireless coverage for a whole construction site using LoRa radio Just log in to your RPX account to access synchronised and live results from any PC or device.

Insite Loggers

Rugged InSite loggers gather the data you need to get the job done right and on-time.

These self-starting sensors detect fresh concrete and begin logging critical data at exactly the right moment.

Triple-redundant thermistors ensure the most precise temperature accuracy and provide peace of mind against data loss.

Temperature measurements are stored every 60 seconds for 180 days and concrete maturity is calculated using 1-minute temperature readings.

Insite Pocket Reader

A simple option to activate, and collect data from self contained Insite Loggers.

The Pocket Reader connects to a WiFi network such as a phone hotspot, and downloads temperature data from Loggers, immediately uploading to Insite cloud software.

A Pocket Reader is able to connect to any number of loggers, downloading temperature and maturity data.

When required a reader may be used away from wireless networks, and manually uploaded later.

Insite Remotes

Data delivery you can trust and power you can rely on.

Insite Wireless Remotes use LoRa radios that extend ranges and use less power expanding your ability to send data and letting you worry less about keeping them going.

Remotes can be set to send data at different intervals so that you can gather critical data more often, or monitor less critical locations less frequently.  All Remotes are powered by low-cost, easy to find AA batteries making them powerful and convenient!

Insite Cloud Software

The InSite cloud-based software presents you with up to the minute concrete data.  Current temperatures and strengths for loggers are easy to access and graph so you know exactly what is happening at any moment.

Alerts can be set to warn you of high or low temperatures, strength thresholds, differential temperatures when monitoring mass pours.  All delivered to you via email or text.

Advantages over Concrete Thermocouples

INSITE loggers are more durable and simpler to operate than a thermocouple based system, benefits include:

  • Automatic concrete maturity and strength calculation, information is available with no processing, site staff can read maturity and strength of concrete in RPX's INSITE Web App.
    There is no need to load data into excel.
  • The most durable logger on the market, better temperature resistance, three redundant thermistor sensors and potting material chosen specifically to prevent water ingress.
  • No Data Loss, each logger is self contained. There is no permanent connection to the remote box needed and even a damaged cable can be re-terminated easily
  • No Programming, loggers are ready to run out of the box, with an automatic start function when the concrete is placed. Just scan or enter the serial number and connect to a remote them to add them to your RPX INSITE account.
  • Simple Installation, rather than working with finicky and expensive thermocouple wire and calibrating, each logger only need be tied into place within the reinforcing cage and the cable led to a point outside the form work

Why the GS9000 matters for SUE businesses

  • Increase area covered per field day
  • Reduce the number of manually positioned survey lines
  • Improve coverage in congested corridors
  • Review coverage before leaving site
  • Produce higher-value mapped deliverables
  • Combine GPR and GNSS in one workflow
  • Retain raw data for later reinterpretation
  • Expand from locating into mapping and subsurface modelling
