Design & prototype thermocouple amplifier board

We want to develop a device to provide a logging output and over temperature alarm from a thermocouple based cylinder head temperature gauge. The gauge head (already purchased) displays the temperature from 2 thermocouples independently.

The device will have the following inputs:

• 12 volt positive from battery (9 to 16 volts)

• Ground (-ve)

• 2 pairs of thermocouple inputs (left cylinder head and right cylinder head)

It will have the following outputs:

• 13.1 volt 5 amp supply for other instruments

• 2 pairs of thermocouple outputs (pass the inputs signals straight through to these outputs)

• Left cylinder head 0-5 volt signal for data logger (0v = 20°C, 5v = 500°C or its Fahrenheit equivalent)

• Right cylinder head 0-5 volt signal for data logger (0v = 20°C, 5v = 500°C or its Fahrenheit equivalent)

• Alarm output to operate an indicator lamp with no external relay. This output would be fired if either channel exceeds threshold temperature.
