What type of pressure gauge is used to measure negative pressure?

A vacuum gauge is specifically designed to measure negative pressure, which refers to pressures below atmospheric pressure. It provides readings that indicate how much lower the pressure is compared to the surrounding atmospheric pressure. This is particularly useful in many applications, such as in vacuum systems and processes where maintaining a specific negative pressure is crucial for efficiency and safety.

The function of a vacuum gauge is tailored to detect slight variations in pressure, allowing operators to monitor systems that operate under vacuum conditions effectively. This is essential in various industries, including food packaging, pharmaceuticals, and manufacturing, where maintaining a negative pressure can influence product integrity and equipment performance.
