I want to measure the temperature of a liquid which is running inside a steel pipe. The temperature can be, at most, 200℃. I want to measure the temperature of that liquid using a sensor/thermometer placed on the outer surface of a pipe, and i need to connect this sensor/thermometer to an Arduino.
From the Arduino, I need to get temperature data which will be shown in a web application.
I have heard about the MLX90614 infrared Thermometer, but it supports only up to 125℃. I need an industry grade sensor for my requirement. Can anyone suggest any other options?
