Mechanical Vacuum Portable Gauging

Mechanical vacuum portable gauging refers to the use of mechanical devices or instruments to measure the pressure or vacuum level in a closed system. These gauges are typically portable, meaning they can be easily moved and used in various locations.

Mechanical vacuum gauges work based on different principles depending on the specific type of gauge. Here are a few commonly used mechanical vacuum gauges:

  1. Bourdon Tube Gauge: This gauge uses a curved tube that straightens or bends based on the pressure difference between the vacuum and the reference pressure. The movement of the tube is then translated into a pressure reading on a calibrated scale.
  2. Pirani Gauge: A Pirani gauge measures pressure based on the thermal conductivity of the gas. It typically consists of a heated wire exposed to the vacuum environment. The cooling effect of the gas on the wire changes its resistance, which is correlated to the pressure level.
  3. McLeod Gauge: McLeod gauges measure pressure by compressing a known volume of gas into a graduated glass tube. The pressure is determined by measuring the change in volume of the gas when compared to the reference volume.
  4. Penning Gauge: Penning gauges utilize the ionization of gas molecules by high-energy electrons in a low-pressure environment. The resulting ion current is measured and used to determine the pressure level.

Portable mechanical vacuum gauges are commonly used in applications such as vacuum systems, HVAC maintenance, leak detection, and vacuum packaging. They offer the advantage of being simple to operate, robust, and relatively cost-effective compared to more advanced electronic vacuum gauges.

What is the principle of servo tank gauge?

The principle of a servo tank gauge is based on hydrostatic pressure measurement. A servo tank gauge is a device used to measure the level and temperature of liquids in storage tanks. It consists of a probe, which is installed inside the tank and a processing unit, which is located outside the tank.

The probe consists of a series of electronic sensors that are mounted at various depths along a long, flexible cable. The cable is lowered into the tank until it reaches the bottom. The sensors measure the hydrostatic pressure exerted by the liquid on the probe, which is directly proportional to the liquid’s depth.

The processing unit receives the signals from the sensors and calculates the liquid level using a microprocessor. The liquid temperature can also be measured using a temperature sensor that is integrated into the probe.

The servo tank gauge uses a servo motor to control the position of the probe inside the tank. The servo motor moves the probe up and down, keeping it in the correct position to measure the liquid level accurately. The servo motor is controlled by the processing unit, which receives signals from the sensors and adjusts the position of the probe accordingly.

The servo tank gauge can provide accurate and reliable measurement of the liquid level and temperature in storage tanks. It is commonly used in the oil and gas industry, chemical industry, and other industries where accurate measurement of liquid levels is critical for inventory control, process optimization, and environmental protection.
