Was wir tun
Dam monitoring data-acquisition systems are unique because of the many types of measurements they are required to collect. Our systems can measure everything from water level and flow to strain and vibration, as well as a variety of other parameters. In addition to real-time data measurement, our systems will alert you of changes in factors such as water level, load, pressure, and tilt if they move beyond acceptable ranges. Our systems are rugged, low power, and adaptable to the harshest, most remote environments. Our team is ready to help you build a dam monitoring system customized to the measurements you need.
Learn about our patented VSPECT® spectral-analysis technology at our VSPECT® Essentials web resource.
The dynamic vibrating-wire measurement technique is protected under U.S. Patent No. 8,671,758, and the vibrating-wire spectral-analysis technology (VSPECT®) is protected under U.S. Patent No. 7,779,690.

Geotechnical Data Acquisition
The versatility of our systems allows them to be customized for each application. We offer a range of dataloggers, from the most basic system with just a few channels to expandable systems that measure hundreds of channels. Scan rates can be programmed from once every few hours to 100,000 times per second, depending on the datalogger model. Measurement types, processing algorithms, and recording intervals are also programmable.
Our systems have powerful onboard instruction sets: simply choose sensor type, scan rate, and measurement channel. On-board mathematical and statistical processing allows data reduction in the field and allows measurements to be viewed in the desired units, whether that be microstrain, centimeters per second, revolutions per minute, meters, Amperes, or inches.
Our system's versatility extends to control as well—our systems can monitor and control external devices based on time or measured conditions, allowing savings in time and equipment, and possibly preventing, or warning of, dangerous conditions. They are rugged enough to be in use in geotechnical studies and mines world wide.
Our systems can stand alone. Once programmed and powered, no human or computer interaction is required, although data are typically downloaded to a PC for further analysis. A telecommunications or hardwire link allows data to be monitored and graphed in your office rather than in the field. Data from a number of stations and from a number of applications can be monitored from a single laptop or desktop computer.
The low power drain typically allows our data acquisition systems to be powered by solar panels and batteries. If 110/220-Vac power, vehicle power, or external 12-Vdc batteries are available, you can use those as well. Nonvolatile data storage and battery-backed clock ensure data capture and integrity.
Sensors used for Geotechnical Measurements
The versatility of our systems begins with sensor compatibility—they can measure virtually every commercially available sensor—allowing them to be used in a variety of ways for a variety of measurements. For example, the a CR10X can be used in slope stability, water quality, or equipment performance applications. Typical sensors that can be used include:
- Carlson strain meters
- Geokon vibrating-wire strain gauges
- Slope Indicator vibrating-strip sensors
- Foil strain gauges (in quarter-, half-,or full-bridge strain configurations)
- Inclinometers
- Crack and joint sensors
- Tilt sensors
- Piezoresistive accelerometers
- Piezoelectric accelerometers
- Capacitive accelerometers
- Borehole accelerometers
- Servo-force balance accelerometers
Because our dataloggers have many channel types and programmable inputs, all of these sensor types can be measured by one datalogger. Channel types include analog (single-ended and differential), pulse counters, switched excitation, continuous analog output, digital I/O, and anti-aliasing filter. Using switched or continuous excitation channels, our dataloggers provide excitation for ratiometric bridge measurements.
Communications
The availability of multiple communications options for retrieving, storing, and displaying data also allows systems to be customized to meet exact needs. Onsite communication options include direct connection to a PC or laptop, PC cards, storage modules, and datalogger keyboard/display. Telecommunication options include short-haul, telephone (including voice-synthesized and cellular), radio frequency, multidrop, and satellite.

Most Campbell Scientific systems are built from individual components. This provides maximum flexibility for our customers, but it does not lend itself to pricing a "typical" system. Contact Campbell Scientific for assistance in pricing a system to meet the unique needs of the application.
