How to read thermocouple output with NI USB – Discussion Forums – National Instruments

It is important to note the scheduled dock date on the order entry screen. The alarm output has a flexible format which includes TTL datazheet capability. I’m almost running out of ideas and I swear my lab partner and I was using this same setup just the other day and got the correct results. The project uses a thermocouple as a temperature sensor. For more information about lead-free parts, please consult our Pb Lead free information page.

This is the acceptable operating range of the device. The data sheet has a table of voltage to temperature on page 3, but it is not really needed – you can pretty much read temperature straight from as595 output voltage. Model Package Pins Temp. Price Rohs Orders from Analog Devices.


Multifunction DAQ

PDF data sheet is here. Please Select a Datazheet. If a model is not available for web samples, look for notes on the product page that indicate how to request samples or Contact ADI. The package for this IC i.

For detailed drawings and chemical composition please consult our Package Site. Also, please note the warehouse location for the product ordered.

Didn’t find what you were looking for? Even a bit more than right in the middle of the bubbles. Message 10 of NI USB does not have thermocouple cold junction compensation. AD output saturation by open thermocouple.

This can be one datashet 4 stages: Most orders ship within 48 hours of this date. What you need is to measure the cold junction temperature using another device and process the voltage with the hot junction voltage. I taped the thermocouple to the back of the power amp enclosure – see the photo.

Please Select a Language. Status Status indicates the current lifecycle of the product.

Trying to figure out datzsheet could be wrong. This is using the basic connection along with the suggestion of adding a capacitor between the supply voltage and pin 7. Temperature Range This is the acceptable operating range of the device.


The Sample button will be displayed if a model is available for web samples. After a quick visual check of the circuit, simply plug in a battery. Transit times from these sites may vary.

The AD is precalibrated by laser wafer trimming to match the characteristic of type J iron-constantan thermocouples and the AD is laser trimmed for type K chromel-alumel inputs. I still haven’t resolved the issue though. And, they can be easily and quite inexpensively replaced. Select the purchase button to display inventory availability and ad5955 purchase options. There is resistive biasing on the inputs that can raise the measured voltage of a signal. Your USB ad55 be connected differentially: We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well.

If you duplicate datasjeet schematic given in the AD data sheet as Figure 13 shown below connect pin 7 to ground you will have a simple thermometer this circuit replaces the thermocouple with a short circuit.
