K/J/E/PT100 Grounded Screw Thermocouple 0-600C

Introduction

A thermocouple is a simple, robust and cost-effective temperature sensor used in a wide range of temperature measurement processes. It consists of two dissimilar metal wires, joined at one end. When properly configured, thermocouples can provide measurements over a wide range of temperatures.

Application

Thermocouples are suitable for measuring over a large temperature range, from −270 up to 3000 °C (for a short time, in inert atmosphere). Applications include temperature measurement for kilns, gas turbine exhaust, diesel engines, other industrial processes and fog machines.

They are less suitable for applications where smaller temperature differences need to be measured with high accuracy, for example the range 0–100 °C with 0.1 °C accuracy. For such applications thermistors, silicon band-gap temperature sensors and resistance thermometers are more suitable。

How to choose a thermocouple?

  1. Determine the application where the thermocouple will be used
  2. Analyze the temperature ranges the thermocouple will be exposed to
  3. Consider any chemical resistance needed for the thermocouple or sheath material
  4. Evaluate the need of abrasion and vibration resistance
  5. List any installation requirements
