Acoustic sensors for pump monitoring
SITRANS DA400 is an acoustic sensor 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 early before they affect the process. The SITRANS DA400 acoustic analyzer can simultaneously and continuously monitor up to four independent delivery valves.
For structure-borne noise measurement
The SITRANS DA400 acoustic diagnostic unit acoustically measures the structure-borne noise
- In the version for pump monitoring; on oscillating displacement pumps
- In the version for material flow monitoring; on pipes, conveying equipment or channels.
It comprises an electric diagnostic unit and up to four acoustic sensors.
Key Features
- Increased plant availability through
- Optimum maintenance scheduling by early detection of faulty components
- Precise leak site identification minimises 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
- Increased productivity
Continuous and independent status monitoring:
- Of the flow control valves, for leaks
- Of the membranes, for material fatigue
- Of the temperature loading of the hydraulic oil
- Of flowing bulk solids in pipes, conveying equipment or channels
Communication of the status to superordinate control systems:
- Via digital outputs
- Digitally, via PROFIBUS DP
Simple to operate and parameterize:
- Locally, via digital display and keys
- PROFIBUS DP
Application
In the version for pump monitoring, the SITRANS DA400 allows continuous, simultaneous and independent monitoring of up to four flow control valves in a pump for leaks. In addition, another four inputs are available for monitoring standard signals (e.g. diaphragm and temperature monitoring). This means that the condition of an oscillating displacement pump is monitored in every phase of its operation.
The SITRANS DA400 is used in all industries where an oscillating displacement pump is used.
The version for material flow monitoring monitors the material flow in liquids or gases that is usually as a result of impact or friction, e.g. against the pipe or channel wall.
