Air Temperature Sensors
Campbell Scientific offers a variety of sensors for measuring air temperature. The electrical signals transmitted from the sensors to our dataloggers can be converted to different units of measurement, including °C , °F, and °K. Our dataloggers are also capable of measuring most commercially available air temperature sensors.

Distributed Data Acquisition
Distributed Data Acquisition seamlessly networks all the components of your integrated monitoring system. The resulting synchronization decreases the quantity and lengths of communications wires between sensors and the data-acquisition system (DAQ).

Soil Heat Flux Sensors
Soil heat flux sensors may consist of several thermocouples whose measurements are averaged, a single thermopile, or a single thermopile with a film heater. These sensors measure the rate of energy transferred through a surface. Data regarding the amount of energy stored in soil as a function of time is used in energy-balance and Bowen-ratio flux systems.

Lightning Warning Sensors
Lightning warning sensors measure the local, atmospheric electric field at the earths’ surface and the fluctuations in field strength. By monitoring the field strength, the potential for cloud-to-ground (CG) lightning discharges can be detected, and advance warning can be made when conditions are becoming favorable for lightning.

Freezing Rain and Ice Detectors
Freezing-rain and ice detectors detect the presence of icing conditions so that appropriate actions can be taken to prevent damage to power and communication lines, to warn of road hazards, to keep ice off a plane’s wings, and to prevent ice from forming on turbine blades.

Global Positioning System Sensors
GPS
GPS sensors are receivers with antennas that use a satellite-based navigation system with a network of 24 satellites in orbit around the earth to provide position, velocity, and timing information.

Water Level, Stage, and Flow Sensors
Campbell Scientific offers a variety of sensors to measure water level, stage, and flow: pressure transducers, shaft encoders, radar ranging sensors, sonic ranging sensors, and bubblers. Users often select their sensors based on the site location, required accuracy level, and ease of installation.

Vibrating Wire Peripherals
Many Campbell Scientific vibrating-wire peripherals enable dataloggers to read vibrating-wire sensors (also known as vibrating-wire or vibrating-strip transducers). These sensors measure strain, load, pressure, and water level, and they output a frequency signal generated by a vibrating filament. Campbell Scientific also offers vibrating-wire dataloggers that read the sensors directly.

Serial Communications
Data cables are used to physically connect two devices so that data can be transmitted between them. For example, a data cable may be used to connect a data logger to a communication peripheral, a data logger to a computer, a computer to a communication peripheral, or one communication peripheral to another.

Solar Radiation Sensors
The solar radiation sensors that Campbell Scientific offers come in a variety of designs: pyranometers, net radiometers, quantum sensors, and pyrheliometers. These sensors measure various aspects of the energy imparted by the sun on the Earth’s surface. A leveling fixture fitted with a bubble level may be required to accurately install solar radiation sensors.

Measurement Devices
In addition to the critical role data loggers play in a data-acquisition system, there are other types of measurement devices. Some measurement devices are used to increase the number of terminals that data loggers can use, which enables them to measure more sensors or control more external devices.

Communication Devices
Communication devices store and retrieve data acquired by data acquisition systems. These devices facilitate the accessibility, analysis, sharing, and reporting of data. Our available communication devices include both on-site and telemetry peripherals, which can be used in the same application for maximum flexibility, convenience, and reliability.

Soil Temperature Sensors
Soil temperature sensors come in a variety of designs using thermistors, thermocouples, thermocouple wires, and averaging thermocouples. The electrical signals transmitted from the sensors to our dataloggers can be converted to different units of measurement, including °C , °F, and °K. Our dataloggers are also capable of measuring most commercially available soil temperature sensors.
