Air Temperature and Relative Humidity Sensors
-
Air temperature and relative humidity probes typically consist of two separate sensors packaged in the same housing. Often relative humidity is measured with a capacitive RH sensor, while air temperature is measured by a PRT.

Power Supplies
-
Reliable power supplies enable data acquisition systems to continuously acquire and process data. Because our components use minimal power, many of our systems can be run using sealed rechargeable or alkaline batteries. Systems that require more power are often supplemented with external rechargeable batteries, regulators, ac transformers, or solar panels.

Soil Water Potential Sensors
-
Campbell Scientific offers soil water potential sensors that measure soil water potential via two methods: heat dissipation or electrical resistance. The sensors determine the energy status of the water in the soil, which describes the force that holds the water in the soil.

Product
Snow Water Equivalent and Snow Depth Sensors
-
Campbell Scientific offers two types of sensors for snowpack applications: snow water equivalent (SWE) sensors and snow depth sensors. SWE sensors measure the amount of water contained within a snowpack. Snow depth sensors measure the depth of the snowpack.

Product
Redox (ORP) Sensors
-
ORP sensors measure the oxidation-reduction potential—the tendency to gain or lose electrons when a solution comes in contact with a chemical substance. ORP measurements are used to ensure that a solution has been completely reduced or oxidized. ORP sensors are often used in tandem with pH sensors, which measure the hydrogen ion activity in a solution.

Narrow-band UHF/VHF Radios
-
UHF and VHF radio products are used in narrowband RF (radio-frequency) telemetry systems. These systems consist of a radio modem and low-powered transceiver at the remote station(s), and a transceiver connected to a modem or base station at the computer site. Up to 254 stations can be interrogated over a single UHF or VHF frequency.

Product
pH Sensors
-
Campbell Scientific pH sensors measure the level of pH in sample solutions by measuring the activity of the hydrogen ions in the solutions. This activity is compared to pure water (a neutral solution) using a pH scale of 0 to 14 to determine the acidity or alkalinity of the sample solutions.

Output and Control Peripherals
-
Output and control peripherals enable you to add channels to control other devices, such as activating external devices and increasing the number of digital output or digital input channels of a data logger. Some of these peripherals have built-in relays to control external devices, and other peripherals may require connected relays depending on what you want to control.

Product
Precipitation Sensors
-
Campbell Scientific offers several types of sensors to measure precipitation: tipping bucket rain gages, siphoning tipping bucket rain gages, heated rain gages, and snowfall adapters. Users often select their precipitation sensors based on the type of precipitation to be measured (rain or snow), as well as the needed orifice diameter, measurement range, and accuracy level.

Product
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.

Product
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.

Product
Conversion Devices and Adapters
-
Conversion devices and adapters fulfill several roles. For example, you can use them to convert an output signal to a signal type that can be measured by a data logger, to adjust resistive bridge measurements, or to build distributed measurement networks.

Product
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.

Dataloggers
CR800-Series
-
CR800-series dataloggers are smaller and designed for applications in which fewer sensors are measured. These dataloggers differ in their keyboard display, as one model offers an external keyboard display, and the other model includes an on-board keyboard display. Multiple CR800-series dataloggers can be configured as a network, or they can be deployed individually.

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.
