Description:
A type K thermocouple is a temperature sensor that has Chromel and Alumel conductors and meets the output standards of ANSI/ASTM E230 or IEC 60584 for type K thermocouples. It can be in different forms, such as an immersion sensor, a surface sensor, a wire, or another type of sensor or cable.
Unlike a J type thermocouple, which has iron and constantan, a K type thermocouple has a nickel/chromium alloy (chrome) and a nickel/aluminum alloy (alumel). These alloys give the K type thermocouple better resistance to oxidation and acidity than the iron parts of the J type.
A K type thermocouple consists of two metal alloys: Chromel (90% nickel, 10% chromium) and Alumel (95% nickel, 2% manganese, 2% aluminum, and 1% silicon). Because the thermocouple is based on nickel, it has good corrosion resistance. This makes it suitable for many applications and situations.

Frequently Asked Questions
What voltage does the K-type Thermocouple – 50cm require?
This thermocouple operates on a 3 to 5.5 VDC supply, compatible with most microcontrollers and data acquisition modules that support SPI communication.
Can I use this thermocouple in corrosive environments?
Yes. The Chromel and Alumel alloys provide enhanced resistance to oxidation and acidity, making it suitable for many industrial settings. However, avoid exposure to strong halogens or reducing atmospheres without protective sheathing.
How do I read temperature data from the probe?
After powering the probe, send SPI read commands to its three-wire interface. The internal cold junction compensation circuit ensures the output reflects the actual junction temperature, which you can convert directly from the digital reading.
