In this topic, you study the difference between active and passive transducers.

A Pirani gauge is a device used to measure low pressure or vacuum levels. Fig. 1: Pirani Gauge.

Thermocouple vacuum gauge operates on the principle of thermo-dynamics, which states that, “At low pressures, Thermal conductivity (Heat conductivity) decreases with decreasing

A McLeod Gauge is a scientific instrument used to measure very low pressures (in the range of 10⁻² to 10⁻⁶
