Replaced by the 1051 - PhidgetTemperatureSensor 1-Input.
The PhidgetTemperatureSensor can be used with E, K, J, and T-type thermocouples. When connected to a K-Type thermocouple, the PhidgetTemperatureSensor can measure temperatures from -200 to +1200 degrees Celsius. The temperature range varies with the type of thermocouple being used.
The 1051 sensor outputs the temperature in Degrees Celsius or as the Potential Voltage generated by the thermocouple probe.
Cold Junction Compensation
The temperature at the point where the thermocouple wires return to the PhidgetTemperatureSensor (the cold junction) must be taken into account. Measurement of this temperature allows for the compensation of temperature variations of the Phidget that would affect the thermocouple voltages. In the case of the PhidgetTemperatureSensor, an on-board temperature sensor continually monitors the board temperature near the connector and provides the data required by the Phidget APIs to adjust for this.
Noise Reduction
On-board filtering reduces noise levels by 80 to 90%.

Welcome to the 1051 user guide! In order to get started, make sure you have the following hardware on hand:
Next, you will need to connect the pieces:
Now that you have everything together, let's start using the 1051!
In order to demonstrate the functionality of the 1051, 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.
To open the Phidget Control Panel on Windows, find the icon in the taskbar. If it is not there, open up the start menu and search for Phidget Control Panel
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 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 1051.
After plugging the 1051 into your computer and opening the Phidget Control Panel, you will see something like this:
The Phidget Control Panel will list all connected Phidgets and associated objects, as well as the following information:
The Phidget Control Panel can also be used to test your device. Double-clicking on an object will open an example.
Double-click on the Temperature Sensor object, labelled Thermocouple Input, in order to run the example:
General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:

Before you can access the device in your own code, and from our examples, you'll need to take note of the addressing parameters for your Phidget. These will indicate how the Phidget is physically connected to your application. For simplicity, these parameters can be found by clicking the button at the top of the Control Panel example for that Phidget.
In the Addressing Information window, the section above the line displays information you will need to connect to your Phidget from any application. In particular, note the Channel Class field as this will be the API you will need to use with your Phidget, and the type of example you should use to get started with it. The section below the line provides information about the network the Phidget is connected on if it is attached remotely. Keep track of these parameters moving forward, as you will need them once you start running our examples or your own code.
You are now ready to start writing your own code for the device. The best way to do that is to start from our Code Samples.
Select your programming language of choice from the drop-down list to get an example for your device. You can use the options provided to further customize the example to best suit your needs.
Once you have your example, you will need to follow the instructions on the page for your programming language to get it running. To find these instructions, select your programming language from the Programming Languages page.
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. As such, in order to measure the temperature at the sensing end we need to know the temperature where the thermocouple connects to the Phidget. To do so, there is an ambient temperature sensor on the board.
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 they 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.
