## Isolated Thermocouple Phidget

ID: TMP1100_0
Recommended for new designs: This product (or a similar replacement with a compatible form, fit and function) is estimated to be available for ten years or more.

Connect one K, J, E or T type thermocouple to this Phidget to measure the temperature of the air, an object, or a liquid.

## $30.00 Quantity Available: 1000+ Qty Price 5$28.50
10 $27.00 25$24.00
50 $21.00 100$19.50
250 $18.00 500$16.50
1000 $15.00 The TMP1100 with an attached thermocouple allows you to measure extreme temperatures. It is great for measuring temperatures in enclosed spaces or in liquids. This Phidget connects to your computer through a VINT Hub. #### Features: • Connects J, K, E or T type thermocouple, choose the type in software and convert to degrees Celsius automatically • If you have other thermocouple types, you can open the channel in VoltageInput mode and convert it to Celsius manually. #### Technical Details • Isolation - The VINT hub and the computer will be protected if anything goes wrong with your circuit • Measure from a distance - Thermocouples have been known to work with wire segments as long as 100m, while USB and other sensors suffer from voltage drops after 5 or 10m. #### Thermocouple Accessories Here are some handy accessories for working with thermocouples. Extension wire, adapters, and plugs can be found here. #### VINT Hubs This Phidget is a smart device that must be controlled by a VINT Hub. For more information about VINT, have a look at the VINT Primer. You can use a Phidget Cable to simply and easily connect the two devices. Here's a list of all of the different VINT Hubs currently available: Product Board Image Part Number Price Number of VINT Ports Controlled By HUB0000_0$30.00 6 USB (Mini-USB)
HUB5000_0 $60.00 6 Local Network (Ethernet or Wi-Fi) SBC3003_0$120.00 6

#### Phidget Cables

Use a Phidget cable to connect this device to the hub. You can solder multiple cables together in order to make even longer Phidget cables, but you should be aware of the effects of having long wires in your system.

#### Thermocouples

You can connect one J,K,E or T type thermocouple to this Phidget. See the product page or data sheet for the thermocouple to determine which end plugs into the positive terminal on the Phidget. If you're not sure which end is which, it won't harm anything to try both configurations to determine which one is right. If the thermocouple is hooked up backward, you'll get erratic readings and the temperature will decrease when it should be increasing.

## Step 1: Install Phidgets Library

1. First, you need to install the libusb-1.0 development libraries. For example, in Debian based distributions:

apt-get install libusb-1.0-0-dev

You’ll also need a C compiler and builder, if you don’t already have one installed.

apt-get install gcc
apt-get install make

## Step 1: Install Phidgets Library

3. Use the following commands in the location you unpacked to install the library:

./configure
make
sudo make install

## Step 1: Install Phidgets Library

4. (Optional) You can also download and unpack the following optional packages:

phidget22networkserver - Phidget Network Server, which enables the use of Phidgets over your network

phidget22admin - Admin tool to track who is connected to your Phidgets when using the network server

libphidget22extra - Required for phidget22networkserver and phidget22admin

libphidget22java - The Java libraries for Phidget22

For installation instructions for these packages, see the README file included with each one.

## Step 2: Connect Devices

● Connect USB Cable to your Linux Computer

● Connect VINT Device(s)

## Step 3: Verify Connection

1. The easiest way to verify that your libraries are working properly is to compile and run an example program. Download and unpack this C example that will detect any Phidget:

## Step 3: Verify Connection

2. Next, open the terminal in the location where you unpacked the example. Compile and run using:

gcc HelloWorld.c -o HelloWorld -lphidget22
sudo ./HelloWorld

ou should receive a “Hello” line for each Phidget channel that is discovered:

I don’t see any Phidgets show up in the HelloWorld example

You need to run it with sudo in order to be able to access USB devices. In order to use Phidgets without sudo, you need to set your udev rules. See the Advanced Information page on the final slide of this guide for details.

## Done!

If you're able to see your devices in the Hello World example, you're done with the Setup part of this guide.

## Part 2: Using Your Phidget

The TMP1100 with an attached thermocouple allows you to measure extreme temperatures. This Phidget connects to a J, K, E, or T type thermocouple. Choose the thermocouple type in software and data will be converted to degrees Celsius automatically. If you have other thermocouple types, you can open the channel in VoltageInput mode and convert it to Celsius manually.

### Explore Your Phidget Channels Using The Control Panel

1. Open your Control Panel, and you will find the following channels:

2. Double click on a channel to open an example program. Each channel belongs to a different channel class:

Expand All
Temperature Sensor (IC): Measures the ambient temperature

In your Control Panel, double click on "Temperature Sensor (IC)":

Thermocouple Input: Reports the probe temperature

In your Control Panel, double click on "Thermocouple Input":

Voltage Input: Measures the raw probe voltage

In your Control Panel, double click on "Voltage Input":

## Part 4: Advanced Topics and Troubleshooting

Expand All
How do I know what channel, serial number, or hub port to use in my program?

Before you open a Phidget channel in your program, you can set these properties to specify which channel to open. You can find this information through the Control Panel.

1. Open the Control Panel and double-click on the red map pin icon:

2. The Addressing Information window will open. Here you will find all the information you need to address your Phidget in your program.

See the Phidget22 API for your language to determine exact syntax for each property.

How can I plot or record sensor data?

In the Phidget Control Panel, open the channel for your device and click on the icon next to the data type that you want to plot. This will open up a new window:

If you need more complex functionality such as logging multiple sensors to the same sheet or performing calculations on the data, you'll need to write your own program. Generally this will involve addressing the correct channel, opening it, and then creating an Event Handler and adding graphing/logging code to it.

The quickest way to get started is to download some sample code for your desired programming language and then search google for logging or plotting in that language (e.g. "how to log to csv in python") and add the code to the existing change handler.

### Filtering

You can perform filtering on the raw data in order to reduce noise in your graph. For more information, see the Control Panel Graphing page.

### Graph Type

You can perform a transform on the incoming data to get different graph types that may provide insights into your sensor data. For more information on how to use these graph types, see the Control Panel Graphing page.

Setting the Change Trigger and Data Interval

The Change Trigger is the minimum change in the sensor data needed to trigger a new data event. The Data Interval is the time (in ms) between data events sent out from your Phidget. You can modify one or both of these values to achieve different data outputs. You can learn more about these two properties here.

Cold Junction Compensation and Self-heating

Thermocouples consist of two junctions, one where the thermocouple meets the Phidget and one where the two wires are welded together at the sensing end of the device. In simplified terms, a thermocouple works by detecting the temperature difference between these two junctions. To measure the temperature at the sensing end we need to know the temperature where the thermocouple connects to the Phidget. There is an ambient temperature sensor on the board. The thermocouple reading is automatically calculated using the data from the on board temperature sensor.

An important thing to note is that the ambient temperature sensor measures the temperature of the board and the air around it, though not specifically at the junction. Generally you can assume the two locations are nearly the same temperature, however as the electronics heat up by being powered on, there can be some small error introduced. This is exacerbated by having the board in an enclosed space where normal airflow is restricted thereby increasing the effect of self-heating. As a result we recommend that the board be left in as open and well ventilated/cooled a place as possible to minimize this error source.
