Study Notes
Pressure Instruments
- Combination Vacuum/ Pressure Gauge: Features two scales, one for negative (vacuum) and one for positive (pressure) readings.
- Liquid Filled Gauge: Often filled with glycerin. This type is known for its resistance to vibration due to the liquid's high viscosity.
- Tank Pressure Gauge: Employed in cylinders and often equipped with alarms.
- Oil Gauge: Used extensively in large pumps and compressors, considered a critical instrument.
- Capillary Gauge: Utilizes a differential pressure tube filled with clean fluid, such as silicone, glycerin, or water. Suitable for duty processes, even with corrosive, unstable, or viscous substances.
- Vacuum Gauge: Employs vacuum measurement units. Ideal for applications where heat sensitivity is a concern.
- Manometer: A pressure instrument filled with water or mercury. Commonly found in furnaces where slightly negative pressure is desired, and also used in conjunction with blowers.
- Digital Gauge: Features a diaphragm, enabling easier reading.
- Delta p Transmitter: Measures the difference between two related pressures. Essential for flow and level monitoring.
- Pneumatic Transmitter: Utilized in areas where spark hazards are a concern. A gauge should be installed nearby in locations without electricity.
- Smart Pressure Transmitter: Allows recalibration from remote locations. Offers the advantage of time and date stamps.
