Application:

SITRANS DA400 for continuous monitoring of oscillating positive displacement pumps. The diagnostic system detects even tiny leaks in the delivery valves. As a result, defects can be detected earlier in their development before they affect the process.

The SITRANS DA400 acoustic analyzer can simultaneously and continuously monitor up to four independent delivery valves. Four additional inputs are also available for sensors for monitoring the pump diaphragms and oil.

System operation and configuration are easily done either locally by LCD and keyboard or via PROFIBUS DP / PA.

Status and alarm notification is signaled to the master process control system via digital outputs or via PROFIBUS DP / PA and also available on the local display.

• Increased plant availability through
  • Optimum maintenance scheduling by early detection of faulty components
  • -recise leak site identification minimizes shutdown and repair time
  • Extended maintenance intervals
  • Increased pump reliability
• Avoidance of costly successive damages
• Increased safety in critical applications
• Early detection of performance declines
• Increase productivity

The SITRANS AS100 is designed to detect changes in high-frequency sound waves from moving equipment and materials, providing instant reactions to variations in solids flow. It serves to alert operators of blockages, product absence, or equipment failures, allowing for timely preventive action and cost avoidance. This system commonly applies to pellets, powders, and bulk solids in various setups such as pipes, chutes, vibratory feeders, pneumatic conveyors, or aerated gravity flow systems.

When paired with a SITRANS CU02 control unit, the AS100 can identify high flow, low flow, or no flow conditions and can be integrated into a control loop via a 4 to 20 mA output. It features two fully programmable independent relays to operate alarms or control devices. Additionally, with its non-invasive nature, lack of moving parts, and robust stainless steel enclosure, it requires minimal maintenance.
