The Air Content Probe and Control System has been designed specifically for use in the pulp and paper industry. It can be used effectively in other applications where the measurement or control of air content is important, such as water/waste and mining industries.

Process Measurement & Controls provides an effective solution to identify and controls problems before they start. The System utilizes high accuracy, durable ceramic sensors that are ideally suited for measuring levels and pressures in paper slurry applications. Other applications include controlling the defoamer in recycling and brownstock washing, and verifying the signal from a consistency meter.

The System provides real-time measurement of entrained or injected gas content in a pre-determined zone of an aqueous suspension. Two PMC flush-mounted pressure sensors are placed in direct contact with process liquid. The sensors are typically fixed laterally on one or more pipes that are firmly held in place on a plate of in flanges mounted on the top or side of a tank, vessel, or flotation cell. The changes in pressure between them provides an accurate measurement of dispersed gas content.

Numerous functional gases are used in pulp and paper manufacturing for processes such as pulp-bleaching liquid-oxidation, pulp and water acidification, ink flotation, and effluent treatment. Unwanted air in these Systems can seriously impair pumping, washing, and papermaking operations. Online monitoring of air content allows for better of aeration in the decontamination and de-inking of wastepaper pulp. Continuous monitoring of air content in the paper slurry helps to control the air bubble size in recycled pulp suspensions.

Dispersed gas creates surface foam in white water, which eventually releases hydrophobic contaminants when the bubbles burst at the surface. This phenomenon contributes to formation of deposits, web breaks, dirt spots and holes in paper. In pulp washing, air bubbles in pulp mats reduce drainage rate and generate foam in the drop leg. The addition of defoamer is essential for coalescing air bubbles in the pulp suspension or in the surface foam. Moreover, presence of air causes some on-line sensors such as microwave consistency meters to malfunction. Conversely, dispersed air may beneficial when introduced on purpose in a suspension, by aspiration or sparging systems. For example, dispersed air flotation is a key step for decontamination of recycled pulps, where both the amount and size of air bubbles directly affects the rate at which ink particles and other contaminants are removed from the suspension.

The probe can be mounted temporarily or permanently in both non-agitated and agitated vessels, over a broad range of temperatures, in corrosive and abrasive media. The system can be easily made portable for monitoring and troubleshooting air content in various site locations.

Speed limiter to protect the operator from overextension.

Units are maintenance free.

Engineered and tested for durability and reliability.

Various mounting arrangements

Solid cast housing and high quality wire rope cable

More control options than a chain hoist of similar capacity

Application

· TT, TN-S ground system.

· Short circuit, overload and earth leakage protection.

Working environment

· Ambient temperature: -35℃~+70℃

· Altitude: ≤2000m

· Relative air humidity: ≤95%

· Pollution degree: 2

· Without obvious shock and vibration

Features

· Short circuit current limiting function.

· High breaking capability of rated short circuit.

· Easy and reliable "frame" connection.

· Standard TH35mm-track installation.

· When the breaker normally opens or trips because of failure protection, phase and neutral wire are both in the state of break to keep the neutral wire from charging.

· During the operation of make or break, neutral wire connects firstly and breaks later.

Rubber air-spring for highly, effective insulation of machinery and subassemblies against impact and oscillation. The bell-shaped component is made of high-grade elastomer. The construction allows a highly effective insulation without the disadvantage of excessive horizontal deflection. It is impossible for the element to break down as a result of overloading or a sudden drop in pressure. To reduce vertical dampening, the component is available with additional attenuation. The baseplate is equipped with an anti-slip plate so there is no need to anchor the machine to the floor.

Note: For outdoor use (e.g. isolation of a roof top air condition unit) the FAEBI® can be supplied in stainless steel and EPDM elastomer version.
