Gas Turbine Compartment Temperature Controller
Temperature Controller of Gas Turbine
The industrial pt-100 temperature controller is designed using
atmel 89c51 family of microcontroller . Analog to digital
conversion: PT-100 temperature sensor is connected to CON1 .Received
signal is conditioned to TTL level before it is given to adc by the ic4
lm358.The lm358 consist of two independent, high gain, internally
frequency compensated which were designed specifically to operate from a
single power supply over a wide range of voltages. The low power supply
drain is independent of the magnitude of the power supply voltage.

Application areas include transducer amplifiers, dc gain blocks and all
the conventional op-amp circuits which now can be more easily
implemented in single power supply systems. For example, these circuits
can be directly supplied with the standard + 5V which is used in logic
systems and will easily provide the required interface electronics
without requiring any additional power supply.
We have following application notes given in the data sheet. For complete details refer to ic datasheet.
Temperature is one of the most common real-world characteristics that
systems need to measure. Many industrial processes, from steel
manufacturing to semiconductor fabrication, depend on temperature.
Some electronics products need to measure their own temperature, such
as a computer that monitors its CPU or a motor controller that must
know the temperature of the power driver IC. Various types of sensors
are used to measure temperature. One of these is the resistance
temperature detector (RTD) which is a wire that changes resistance with
temperature. Typical RTD materials include copper, platinum, nickel, and
nickel/iron alloy. An RTD element can be a wire or a film, plated or
sprayed onto a substrate such as ceramic.
RTD resistance is specified at 0∞C. A typical platinum RTD with 100W
resistance at 0∞C would have a resistance of 100.39W at 1∞C and a
resistance of 119.4W at 50∞C. The tolerance of RTDs is better than
thermistors, typically ranging from .01% for platinum to .5% for nickel.
RTD has better tolerance and overall lower resistance.
