Question 1

What is a Pirani vacuum gauge?

Accepted Answer

A Pirani vacuum gauge measures low vacuum pressures using thermal conductivity principles, providing accurate readings in various applications.

Question 2

How does a Pirani gauge work?

Accepted Answer

It measures the thermal conductivity of gases, where the heat loss from a heated filament varies with the pressure of the gas around it.

Question 3

What are the typical applications for Pirani vacuum gauges?

Accepted Answer

They are commonly used in semiconductor manufacturing, material testing, vacuum packaging, and research laboratories.

Question 4

What is the pressure range of Pirani gauges?

Accepted Answer

Pirani gauges typically measure pressures from 10^-3 to 1,000 mbar, making them suitable for low to medium vacuum applications.

Question 5

Are Pirani gauges suitable for corrosive gases?

Accepted Answer

No, Pirani gauges are not recommended for corrosive gases as they can damage the sensor. Alternative gauges should be considered.
