How We Can Help You

Campbell Scientific’s measurement automation platform has been created with over 45 years of experience in the design and manufacturing of geotechnical monitoring and data-acquisition systems. Campbell Scientific is well recognized for monitoring platforms used globally in some of the most extreme and unforgiving environments on Earth. Each platform provides accuracy and reliability for critical applications, where human lives are often at stake. Simple interfaces, ease of setup, and long-term reliability make it the preferred platform for service providers in geotechnical monitoring applications.

  • Reduce uncertainty. Built to reduce project uncertainty through automated measurements with data integrity, security, quality control, and local alarming capabilities
  • Efficient operations. Built to make measurement automation setup and long-term operation simple and fast
  • Scalable. From small, single projects to large-scale, multi-site operations
  • Open ecosystem. Plug-and-play, self-configuring, and capable of interfacing with any sensor, Campbell Scientific allows you to own your data, own your network, and control your configuration.
  • Data sharing. Powerful reporting, dashboard building, and built-in data sharing tools keep everyone informed. Designed for you and your stakeholders.

Measurement automation platforms are unique to each application because of the many types of measurements they are required to collect.

The versatility, ruggedness, and reliability of Campbell Scientific monitoring systems make them ideal for all geotechnical monitoring needs, including, but not limited to, water level, water quality, slope stability analysis, weather monitoring, ambient air quality, environmental compliance, dam and tailing monitoring, mine ventilation, and equipment performance.

In addition to real-time data measurement, each measurement device will alert you of changes in factors such as water level, load, pressure, and tilt if they move beyond acceptable ranges. Historical and real-time data can be transmitted directly to the cloud or to your PC. Measurement automation platforms are rugged, low power, and adaptable to the harshest, most remote environments.

Having a design that can operate in harsh remote locations—where unsafe conditions are often not suitable for personnel—and be reliable enough to keep people safe is absolutely a necessity. Campbell Scientific automated monitoring systems provide many benefits:

  • Reduced resources (work hours, fuel, safety risks) required to have personnel manually collect data from sensors
  • Increased data availability (data available 24/7)
  • Improved data integrity
  • Better worker and public safety
  • Ability to monitor critical parameters even during shutdown or long-term care and maintenance
  • Cost-effective implementation of governance around environmental and safety solutions

Allow our team of experienced application engineers to make this easy as they help you build a monitoring system specific to the measurements you need.

More Details about Our Geotechnical Systems

Geotechnical Measurement Automation Platforms

The versatility of our platforms allows them to be customized for each application. We offer a range of platforms, from the most basic device with just a few channels to expandable platforms that measure hundreds of channels. Scan rates can be programmed from once every few hours to 10,000 times per second, depending on the model. Measurement types, processing algorithms, and recording intervals are also programmable.

The measurement automation platform has a simple, yet powerful on-board instruction set. Simply choose the sensor type, scan rate, and measurement channel. On-board mathematical and statistical processing allows data reduction in the field and enables measurements to be viewed in the desired units, whether that is microstrains, centimeters per second, revolutions per minute, meters, Amperes, or inches.

The versatility of the measurement automation platform extends to control as well. Each platform can monitor and control external devices based on time or measured conditions, allowing savings in time and equipment, and warning of—or possible prevention of—dangerous conditions. These platforms are rugged enough to be used in geotechnical sites worldwide.

The measurement automation platform can stand alone. Once programmed and powered, no human or computer interaction is required, although data are typically downloaded to a PC or exported to the cloud for further analysis. A telecommunication or hardwire link allows data to be monitored and graphed in your office rather than in the field. Data from various stations and applications can be monitored from a single laptop or desktop computer.

The low power drain typically allows our platforms to be powered by solar panels and batteries. If 110/220-Vac power or external 12-Vdc batteries are available, you can use those as well. Nonvolatile data storage and a battery-backed clock ensure data capture and integrity.

Sensors Used for Geotechnical Measurements

The flexibility of our measurement automation platforms begins with sensor compatibility. Our platforms can measure virtually every commercially available sensor, allowing them to be used in different ways for a variety of measurements. For example, the following are common parameters that the sensors in our platforms measure:

  • Barometric pressure
  • Pore water pressure
  • Water level
  • Water flow
  • Temperature
  • Weight
  • Force
  • Pressure
  • Strain
  • Tilt
  • Deflection
  • Inclination
  • Settlement
  • Displacement
  • Elevation
  • Humidity

More specifically, these are the sensor types commonly used in our measurement automation platforms:

  • Foil-bonded strain gauges
  • Vibrating-wire strain gauges
  • Strainmeters
  • Extensometers
  • Jointmeters
  • Crackmeters
  • Deformation meters
  • Piezometers
  • Pressure transducers
  • Barometers
  • Settlement sensors
  • Borehole pressure cells
  • Earth pressure cells
  • Load cells
  • Pressure cells
  • Inclinometers
  • Tiltmeters
  • Tilt beams
  • Stressmeters
  • Thermistors
  • Thermocouples
  • Deformation sensors
  • Accelerometers
  • Sonic water-level sensors
  • Displacement transducers
  • Linear variable differential transformers (LVDT)

Because our measurement automation platforms have many channel types and programmable inputs, all these sensor types can be measured by one device. Channel types include analog (single-ended and differential), pulse counter, switched excitation, continuous analog output, digital I/O, and anti-aliasing filter. Using switched or continuous excitation channels, our platforms provide excitation for ratiometric bridge measurements.

The following are common sensor measurement types that our measurement automation platforms are compatible with:

  • Frequency
  • Resistance
  • Voltage
  • Ratiometric
  • Current
  • Modbus RTU
  • RS-485
  • SDI-12

Communications

The availability of multiple communications options for retrieving, storing, and displaying data also allows platforms to be customized to meet your exact needs. Onsite communications options include direct connection to a PC or laptop, PC cards, storage modules, and platform keyboard/display. Telecommunications options include short-haul, telephone (including voice-synthesized and cellular), radio frequency, multidrop, and satellite.
