Weeder Technologies Thermocouple Input cards with free Window's software
The most common way to measure temperature in an industrial environment is to use a thermocouple sensor together with a voltage adapter and display device or reader to view the data. However, this form of sensor does not have a linear output so simple amplification and signal conditioning via an op-amp circuit is not adequate enough by itself to determine the temperature of the thermocouple tip or probe. Our Thermocouple Input card which plugs into an RS-232 or USB port of a PC or laptop uses a built-in polynomial math routine inside the amplifier for the thermocouple conversion. This converts the voltage at the thermocouple's output to a temperature reading that can be displayed on the computer screen and used for data logging.
