tested two different types of thermocouples‚ a T-type and a J-type. Measuring with a thermocouple allows us to measure the temperature difference between two junctions. There are several laws that deal with the thermocouples and reading of temperatures. We use the first law of thermodynamics which states that there is a conservation of energy. Also the law of homogenous metals is in effect. This law basically states that two different metals are needed for the thermocouple to function properly. The

TRANSDUCERS Transducers are electric or electronic devices that transform energy from one form to another. A transducer is a device that converts one form of energy to other form. It converts the measureand to a usable electrical signal. In other word it is a device that is capable of converting the physical quantity into a proportional electrical quantity such as voltage or current. Industrial uses of transducers - Temperature‚ force‚ strain‚ liquid level‚ flow rate‚ electrical conductivity

temperature is outside the cabin P3C M2 The temperature of the air in the cabin is controlled by various sensors such as thermostats these are place all over the cabin so there is a level temperature throughout the cabin. There is also thermocouples and thermistors which are placed in various places such as the output of the air conditioning pump which pumps out the air into the cabin. All of these sensors are linked to the temperature control valve which mixes the ram air with bleed air to
