Measurement & Automation

We use this since 2012 and the best measurement product ever. Don't be fooled by their price tag. Super built quality and very responsive technical support. mostly all your question will be answer below than 24 hours. Here is little article about this product. USB DAQ device with 16 flexible I/O, and 4 dedicated digital I/O. The flexible I/O can be configured as either digital or analog, thus providing up to 16 analog inputs, or up to 20 digital I/O. It also has two 10-bit analog outputs, up to 2 counters, and up to 2 timers.

Analog Inputs:

The LabJack U3 has up to 16 analog inputs available on the flexible I/O lines. Single-ended measurements can be taken of any line compared to ground, or differential measurements can be taken of any line to any other line.

Analog input resolution is 12-bits. The range of single-ended low-voltage analog inputs on the U3-LV is typically 0-2.4 volts or 0-3.6 volts, and the range of differential analog inputs is typically ±2.4 volts (pseudobipolar only). For valid measurements, the voltage on every analog input pin, with respect to ground, must be within -0.3 to +3.6 volts.

On the U3-HV, the first 4 flexible I/O are replaced with dedicated high-voltage analog inputs. The input range of these channels is ±10 volts or -10/+20 volts. The remaining 12 flexible I/O are still available as described above, so the U3-HV has 4 high-voltage analog inputs and up to 12 low-voltage analog inputs.

Command/response (software timed) analog input reads typically take 0.6-4.0 ms depending on number of channels and communication configuration. Hardware timed input streaming has a maximum rate that varies with resolution from 2.5 ksamples/s at 12-bits to 50 ksamples/s at about 10-bits.

T7, Raspberry Pi 3, and Cloud9

Combining the processing power from today's latest single board computers with LabJack's DAQ devices allow for some really cool projects. The T7's built-in Lua Scripting feature allows for the T7/T7-Pro to operate as a stand alone device however sometimes projects require more processing power. The Raspberry Pi 3 has a quad core ARMv8 CPU, WiFi, Ethernet, and Bluetooth 4.1 however it is missing industrial strength, precision, calibrated analog inputs which you get when you connect a T7. This tutorial will hopefully help some of our customers get started with the Raspberry Pi and the T7 as well as introduce existing Raspberry Pi users to the idea of using Cloud9 as a remote IDE that is introduced by the BeagleBone Black. Developing directly on a Raspberry Pi can sometimes be slow as you don't have access to modern web-browsers and it usually takes up one of your monitors. With Cloud9 running locally on the Raspberry Pi you can simply navigate to the device's IP address and code away!
