Pico ADC-24 - 16 Channel, 24-bit Resolution Precision Data Logger

The ultimate in resolution and accuracy

With up to 24-bit resolution the ADC-20 and ADC-24 USB data loggers are able to detect small signal changes. Features such as true differential inputs, galvanic isolation, and software selectable sampling rates, all contribute to a superior noise free resolution, and ensure that your measurements are reliable and are accurate.

All Pico data acquisition products come complete with PicoLog - this powerful, yet flexible, data acquisition software allows you to collect, manipulate, analyze, and display and export data. With PicoLog you can sample up to one million readings at selectable sampling rates; and using PicoLog, or our driver with your own software, you can connect up to four units to one PC.

Flexible, multichannel data acquisition

Both the ADC-20 and ADC-24 feature true differential inputs for excellent noise rejection. To give you a very flexible system each differential input can also be configured as two single-ended inputs. With up to eight differential or 16 single-ended inputs on the ADC-24, this flexibility gives you complete control on what type of inputs you use. If you require more channels then you can use multiple PicoLog data loggers on the same PC.

With as many as seven bipolar voltage ranges, the ADC-20 and ADC-24 are also flexible enough to be used with a wide range of sensors and signal types. There's also an optional terminal board provides screw terminals to allow you to quickly connect and disconnect different sensors.

Additionally, the ADC-24 has four configurable digital input/output channels that can be used to control alarms or other devices.

The flexibility of these precision data loggers allows you to use the ADC-20 and ADC-24 as an advanced multichannel data acquisition system with a low cost per channel.

No need for power supplies or batteries

The high-resolution ADC-20 and ADC-24 are powered directly by your PC - eliminating the need for batteries or a separate power supply, and making them ideal when you need a portable data logger.

The answer to your data acquisition needs

High resolution, true differential inputs, galvanic isolation, and selectable sampling rates combine to ensure that your measurements are always precise and accurate. Configurable inputs, digital inputs and outputs, and programmable voltage ranges give you a truly flexible answer to your data acquisition needs. When you need the ultimate in high resolution and accuracy, the versatile ADC-20 and ADC-24 provide you with a portable answer with the performance and flexibility you need.
 

ADC-20 and ADC-24 Software

Spreadsheet view

Displays text data in a format that can be easily copied and pasted into other applications. Data can also be saved to disk in standard ASCII text format.

Graph view

Graphs can be displayed both during and after data collection. Each channel can be displayed in its own graph or multiple channels can be displayed in the same graph. Axes can be set up manually, automatically or in chart recorder mode. Multipliers allow you to magnify areas of interest. Graphs can be copied and then pasted into reports.

XY graph view

Displays one parameter against another. Useful for plotting voltage against current, for example.

Player view

Displays previously recorded data. It enables you to scroll quickly through stored files to compare results on successive runs. The player can be used to examine old data while new data is still being recorded.

Parameter scaling can be used to convert raw data into standard engineering units. A wide range of equation and table lookup scaling options are provided. Additional parameters can be calculated. For example, to calculate power output from a boiler you may need to multiply a flow reading from one channel with the temperature difference between two further channels. Alarm limits can be set for each channel to alert the user should a parameter go out of a specified range.

Software Development Kit (SDK)

As well as the supplied PicoLog software, also included are drivers and examples for those who want to write your own software or interface to other programs. Software drivers are supplied for Microsoft Windows, Apple Mac (OS X) and Linux (including Raspberry Pi and BeagleBone).

Example code shows how to interface to third-party software packages such as Microsoft Excel and National Instruments LabVIEW as well as how to write your own software in C++ / C#.
