Sensors

Introduction Pressure Sensors – Motorola A sensor is a device that produces a measurable response to a change in a physical condition, such as temperature or thermal conductivity, or to a change in chemical concentration. Sensors are particularly useful for making in-situ measurements such as in industrial process control. Sensors are an important part to…

Thermocouple

thermal junction, thermoelectric thermometer, or thermel, a temperature-measuring device consisting of two wires of different metals joined at each end. One junction is placed where the temperature is to be measured, and the other is kept at a constant lower temperature. A measuring instrument is connected in the circuit. The temperature difference causes the development of an electromotive force (known as the Seebeck effect)…

Thermocouple Construction and Color Codes

The Thermocouple The Thermocouple is by far the most commonly used type of all the temperature sensor types. Thermocouples are popular due to its simplicity, ease of use and their speed of response to changes in temperature, due mainly to their small size. Thermocouples also have the widest temperature range of all the temperature sensors from below…

5 Ways To Spot A Quality Exhaust Gas Temperature Probe (EGT)

1. Know if it is made with Mineral Insulated Cable. There are two main ways EGTs can be constructed. One way uses Mineral Insulated (MI) Cable. The other way uses thermocouple wire inside of a Stainless-Steel Tube. Quality EGTs will always be made using MI Cable. MI Cable uses Magnesium Oxide (MgO) Powder to insulate…
