I am trying to find out if type K thermocouple is capable of transmitting power from an external power supply to a camera and some lamps attached on the end. I have 3 pairs of thermocouples. One pair for the camera supply. One pair for the video output. One pair for the lamps. I have tried google for answers but have found very little useful information. Thermocouple specs: Length approx 75m type K 22AWG loop resistance 0.9368Ω/foot Camera specs: 11.5V to 15V DC 400mA to 500mA Video output specs: 2V p-p into 150Ω Lamps Specs 0.5A 12V DC LEDs Analysis i have done so far: Resistance of thermocouple- 246x0.9368=231Ω Voltage drop across the thermocouple- V=IR=0.4x231=92.4V If the current was to decrease by 10mA this would cause the voltage at the camera to decrease by 2.3V- 0.39x231=90.1V If the resistance was to increase by 1Ω then the voltage will increase by 0.4V- 0.4x232=92.8V At a lamp supply of 0.5A the power dissopated over the length of the thermocouple would be approx- P=IIR=0.5x0.5x231=57.75W Equating to 0.77W/m I look forward to your responses.
