VACUUM METER
Features:
-
Measurement of Vacuum: Vacuum meters are designed to measure the level of vacuum within a system. Vacuum is essentially a pressure measurement below atmospheric pressure, and it is commonly expressed in units such as inches of mercury (inHg), millimeters of mercury (mmHg), or pascals (Pa).
-
Types of Vacuum Meters:
- Manometer: A simple U-tube manometer filled with a liquid, such as mercury or oil, is one of the oldest and most basic forms of vacuum meter. The difference in liquid levels indicates the vacuum level.
- Bourdon Tube Gauge: Bourdon tube vacuum gauges use a curved, flattened tube that straightens as vacuum pressure decreases. This motion is used to indicate the pressure on a dial.
- Piezoelectric Transducers: Some modern vacuum meters use piezoelectric crystals to measure the strain caused by vacuum pressure. This strain is converted into an electrical signal for measurement.
- Pirani Gauge: Pirani gauges operate on the principle that the thermal conductivity of gas decreases with lower pressure. They measure the heat transfer from a heated wire suspended in the vacuum.
-
Applications:
- Laboratory Use: Vacuum meters are widely used in laboratories for experiments and processes that require precise control of vacuum levels, such as chemical reactions, material testing, and vacuum distillation.
- Industrial Processes: Industries like semiconductor manufacturing, pharmaceuticals, and food processing rely on vacuum meters to control and monitor vacuum levels in various production processes.
- Automotive: In automotive applications, vacuum meters can measure engine vacuum, which is essential for diagnosing engine performance issues and tuning.
-
Vacuum Ranges: Vacuum meters come in different models with varying vacuum measurement ranges. The appropriate vacuum meter is chosen based on the expected vacuum level within the system.
