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.

Part 1: Setup

Welcome to the TMP1100 user guide! In order to get started, make sure you have the following hardware on hand:


Next, you will need to connect the pieces:

TMP1100 Functional.jpeg
  1. Connect the thermocouple to the inputs on the TMP1100. The datasheet or product page for the thermocouple should tell you which wire is positive and which is negative.
  2. Connect your device to your VINT Hub using the Phidget cable.
  3. Connect the VINT Hub to your computer.


Now that you have everything together, let's start using the TMP1100!

Phidget Control Panel

In order to demonstrate the functionality of the TMP1100, the Phidget Control Panel running on a Windows machine will be used.


The Phidget Control Panel is available for use on both macOS and Windows machines.

Windows

To open the Phidget Control Panel on Windows, find the Ph.jpg icon in the taskbar. If it is not there, open up the start menu and search for Phidget Control Panel

Windows PhidgetTaskbar.PNG

macOS

To open the Phidget Control Panel on macOS, open Finder and navigate to the Phidget Control Panel in the Applications list. Double click on the Ph.jpg icon to bring up the Phidget Control Panel.


For more information, take a look at the getting started guide for your operating system:


Linux users can follow the getting started with Linux guide and continue reading here for more information about the TMP1100.

First Look

After plugging the TMP1100 into your computer and opening the Phidget Control Panel, you will see something like this:

TMP1100 Panel.jpg


The Phidget Control Panel will list all connected Phidgets and associated objects, as well as the following information:

  • Serial number: allows you to differentiate between similar Phidgets.
  • Channel: allows you to differentiate between similar objects on a Phidget.
  • Version number: corresponds to the firmware version your Phidget is running. If your Phidget is listed in red, your firmware is out of date. Update the firmware by double-clicking the entry.


The Phidget Control Panel can also be used to test your device. Double-clicking on an object will open an example.

Part 2: Using Your Phidget

About

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

You can use your Control Panel to explore your Phidget's channels.

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:

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":

2. Phidget Programming Basics

Part 4: Advanced Topics and Troubleshooting

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:

The locate Phidget button is found in the device information box

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

All the information you need to address your Phidget


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

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.
