We have professionally designed and specified data collection electronics to interface your Arduino, BeagleBone or Raspberry PI to the real world. These circuits will accelerate your development program while lowering your project costs. We work to provide the information to allow the user to enhance each of our circuits as needed.
We offer a fully assembled standard product and a partially populated product where you make it yours! We have the schematics, we can provide some engineering insight, YOU make the call to best meet your NEEDS.
Our head designer Randy Normann has over 30 years’ experience designing logging and drilling electronics for geothermal applications. Randy has developed both conventional heat-shielded and barefoot tools (up to 290°C continuous operation). A partial list of his designs: production logging tools (pressure, temperature, spinner with CCL), fast SRO fracture monitoring tools, continuous HT well-monitoring systems, high-speed MWD tools, core-tube monitoring electronics, spectral gamma tools along with a wide range of other scientific laboratory instrumentation.
If you want to take your Arduino sensor measurement skills to the next level…..
If you want to publish your findings in scientific publications….
If you want to design a data collection system as part of a research team….
If you’re a geologist, physicists, volcanologist or any science driven person wanting to learn how to make
your own electronic measurements…..
Then Randy wrote this book for you.
22 Bit ADC
3 μV Typical Offset Error (2.5V range)
3.0 to 5.5V operating range
On board low noise power supply filter
On board 2.5V Voltage Reference
On board 1M ohm voltage divider for 0-5V input
On board RC input filter
Clean supply and reference voltage for sensor use
This is the same AD22B but the analog input resistors and capacitors are NOT installed. They are 805 surface mount components. Most users will have no trouble installing their own parts to create the interface they need. We can supply the parts for a small additional cost. If interested in our parts, email us for our parts list.
12 Bit DAC (Digital to Analog Converter), MCP4921
0V to 10V Programmable Voltage
On Board 2.5V Voltage Reference
On Board Power Transistor
On Board PTC Fuse Rated to 50mA
On Board Current Measurement Amplifier
The InAmp Shield is based on the AD8226 instrumentation amplifier from Analog Devices, Inc. This shield allows the measurement designer to take full advantage of the AD8226 for amplifying very large number of analog sensors as: bridge strain, thermocouple or RTD temperature, pressure sensors, current flow measurements and more.
PT Well Monitoring or Logging Electronics
This is an analog interface for driving pressure and temperature signals up a standard mono-conductor logging cable or wired tubing. The logging cable can be used to support well testing while wires inside tubing can be used for permanent well monitoring. At the surface, the AD22B and DAC12B can supply power and convert the sensor signals to digital values.
Temperature is a 3 wire RTD for accuracy and a wide temperature range.
Pressure is any bridge strain type analog pressure transducer such as those from Paine Electronics, Emerson.
