The thermocouple is one of the oldest and most widely used electronic temperature sensing devices. It consists of two wires, made from two dissimilar metals, that are welded together at one end. This creates a junction where the temperature is measured.
There are many types of thermocouples, each with its own unique characteristics in terms of temperature range, durability, vibration resistance, chemical resistance and application compatibility. They provide a fast thermal response, are unaffected
by vibration, are self-powered and can withstand temperatures ranging from -270°C to 2100°C, making them extremely versatile and ideal choices for use in harsh environmental conditions. They can be used in an array of applications in the industrial,
medical, automotive, automated manufacturing processes and consumer markets.
Our innovative portfolio of highly integrated thermocouple conditioning IC solutions simplifies your development and speeds up your product’s time to market. These devices integrate a precision high-resolution Analog-to-Digital Converter (ADC),
a precision high-accuracy temperature sensor (for cold junction compensation) and precision instrumentation that corrects the thermocouple non-linear error characteristics of eight of the most popular thermocouple types used today. An on-board, preprogrammed math engine enables these ICs to accurately measure temperature through real-time non-linearity thermocouple corrections up to a ninth order equation.
