Temperature measurement circuit schematic
The multimeter is a measurement device most used by engineers and we use it in this temperature measurement circuit schematic. The temperature sensor is LM335 wich has a linear characteristic of 10mV / K . In the production process this electronic device is calibrated so can provide 2.73V at 00C. LM336 is used as a very precise 2.5V Zener diode; CA3040 amplification can be adjust between 1.08 and 1.10 times thru P1. This temperature measurement circuit can be used for Fahrenheit measurements, in this case the freezing point is adjusted at 320F. At 2120F, P2 is adjusted to obtain 0.9V at output.
So 10F correspond to 5mV. The total current consumption is 10mA.
