Measurement & Control Peripherals Expand your datalogger's measurement and control ability

About Measurement & Control Peripherals

This family of peripherals expands the already formidable measurement and control capabilities of Campbell dataloggers.

Measurement peripherals are situated between the datalogger and its sensors, while control peripherals are situated between the datalogger and external device(s) under datalogger control.

Multiplexers

Multiplexers allow our data loggers to measure more sensors. The number of analog inputs is increased by sequentially multiplexing sensor leads into "common" leads. The individual common leads are con...read more

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 betwe...read more

CDMs

Campbell Distributed Modules (CDMs) are the measurement devices that scale the channel count beyond what is found in the standard dataloggers, add functionality to a datalogger that it does not normal...read more

Expansion Peripherals

Expansion peripherals are used with data loggers to achieve many purposes, including the following: extend data communications networks, perform media conversions, read vibrating-wire sensors, and bui...read more

Synchronous Devices for Measurement

Synchronous Devices for Measurement (SDMs) are a group of addressable peripherals that expand the datalogger's output and measurement capabilities. The datalogger controls the SDM output device by sto...read more

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 meas...read more

Vibrating-Wire Peripherals

These products allow our dataloggers to read vibrating-wire sensors. Vibrating-wire (or vibrating-strip) transducers are commonly used to measure strain, load, pressure, and water level. These sensors...read more

Time-Domain Reflectometry (TDR)

Time Domain Reflectometry (TDR) is widely used to measure soil water content, bulk electrical conductivity, and rock mass deformation. TDR measurements are nondestructive and offer excellent accuracy...read more

What do measurement and control peripherals do?

Our measurement and control peripherals, including SDMs, multiplexers, and Terminal Input Modules (TIMs), expand the measurement and control capabilities of the datalogger.
What does a multiplexer do?

A multiplexer allows switched excitation channels and analog inputs to be shared. By using one channel to measure multiple sensors, the number of sensors that can be measured increases.
What are SDMs, and what do they do?

SDM refers to Synchronous Device for Measurement. SDMs expand digital control ports, analog output ports, and measurement capabilities. They are addressable devices, allowing more than one to be connected to a datalogger at the same time.
