The product lines we represent are as follows:

Datalogger and Sensors

Campbell Scientific manufactures dataloggers, data acquisition systems, and measurement and control products used worldwide in research and industry. Their instrumentation is known for its flexibility, precision measurements, and dependability - even in harsh, remote environments.

Almost any sensor, individual or multiparameter (Hydrolab, YSI, Eureka, In-Situ), may be used with the system, allowing the system to be customized for each application. We helped create the original SDI-12 standard, so you can be sure our systems are SDI-12 compatible. In addition, nearly all available flow, level, and meteorological sensors can be measured and recorded to meet client specific applications.

Almost any meteorological sensor can be measured by our dataloggers, allowing stations to be customized for each site. Typical sensors used on our stations include, but are not limited to: Wind speed and direction, Solar radiation, Temperature (air, water, soil), Relative humidity, Precipitation, Barometric pressure, Soil moisture. At some locations, hydrological sensors provide additional measurements, such as water level of a nearby stream.

Campbell Scientific SCADA systems consist of a supervisory computer running HMI (Human-Machine Interface) software and control units performing data acquisition and control functions. The control units make measurements as well as report back to and execute commands from the supervisory computer. The versatility and reliability of our control units set our systems apart from others. These units provide many benefits that PLCs do not.

1. Control units function as PLCs, RTUs, or DCUs.
2. Control units perform advanced measurement and control independent of the central computer.
3. PID control continues, even if communications to the main computer are lost.
4. Control units have many channel types to measure most available sensors.
5. Systems are compatible with our own or other vendors' HMI software packages.
6. Control units have their own UPS; during ac power loss, they continue to measure and store time-stamped data.
7. Control units provide on-board statistical and mathematical processing.
8. Systems are easily expandable: add new sites or add sensors to existing sites.
9. Control units have wide operating temperature ranges and operate in rugged environments.
