Re: Thermocouples and Temperature Display

Please correct me if I am wrong, but I am presently under the impression that there is no way to mirror an input on a VINT hub to an output on a VINT hub. In this case, it might be that what I had hoped to do is not going to work without going the SBC route, which also might not work as I still need...

Thermocouples and Temperature Display

I am currently reading temperatures up to 500°F using thermocouples, TMP1101 and HUB0000 via USB. I would also like to display the temperatures on a pair of 4 character 7 segment led displays such as the Arduino TM1637. How would you approach a solution to this problem? The Phidgets SBC seems like o...

Re: Measuring Natural Gas Pressure

I' coming along late here and maybe you have already solved this problem, but here was my solution. I use Dwyer Magnehelic Differential Pressure Transmitters to read both air pressure and natural gas pressure, and then use the DAQ1400 to read the signal from the transmitters. It's very reliable and ...

Re: Multiple DAQ1400s on VINT HUB0000?

Thank you for your suggestions. I am attaching Dwyer Series 605 Magnehelic Differential Pressure Indicating Transmitters to the DAQ1400's and the power supply is a MacBook Pro laptop computer and I am running everything at 12v. I believe I identified a problem with one of my Indicating Transmitters ...

Re: Rostmaster & Raspberry

I am working on a solution for logging more roast details with Artisan, and once I have the solution worked out with physical inputs via USB, I will make it wireless with Raspberry Pi and build everything into a box mounted to my control panel. So far I have thermocouples for BT and ET, and differen...

Optical Tachometer Phidget

Optical tachometers are everywhere these days, and people are finding all sorts of uses for these portable devices. But sometimes you want one in a fixed position for constant data collection. This would make an ideal phidget as the circuit is simple, and its uses for measuring the rate of rotation ...

Multiple DAQ1400s on VINT HUB0000?

I assume it should be possible to use multiple DAQ1400 input devices with a VINT hub, but I have run into a problem. I have two pressure transmitters that provide a 4mA-20mA signal. Both properly transmit within that range. I have 2 DAQ1400 units plugged into 2 ports on a HUB0000. When I wire the fi...
