Locate the source, drive and receiving position for this task
Required inputs are the specific sensor configuration, location, liquid/tubing, sampling rate, thresholds and time windows. Confirm liquid contact, pressure and destination along each illustrated section before defining drive and connection responsibilities.
Select sensing position and range from the target faults
Define target faults and permitted response time before selecting sensing locations, tubing and signal range. Confirm ABD and PDM5 capabilities for the actual configuration; unverified ranges or accuracy are not guaranteed.
| Condition to compare | Information required | Selection affected |
|---|---|---|
| Monitoring objective | Loss of liquid supply, bubbles, blockage or leakage | Select measurement locations and supporting checks |
| Time correlation | Current aspiration, dosing or switching stage | Define appropriate signal ranges for different actions |
| Controller response | Potentially affected sample, recorded delivery and restart conditions | Connect alarms to actionable responses |
Compare product options against task requirements
The following candidate options match this page's responsibilities. Compare them against the operating conditions described, then check capacity, materials and interfaces on the product pages. Card images show representative configurations; suitability must still be confirmed at actual operating points and by application results.
| Product category | Corresponding role | Confirm before selection |
|---|---|---|
| ABD bubble-detection module | Bubble or liquid-state identification in defined tubing | Validate detection and false alarms for tubing material, dimensions, medium and action window |
| PDM5 pressure-detection module | Pressure-state monitoring at a defined fluidic location | Confirm range and wetted configuration by model; validate normal baseline and abnormalities separately |
Establish decision criteria for each action stage
Establish normal-operation baselines and assess sampling, dosing, washing and shutdown separately. The controller should associate alarms with the current sample, valve position and recorded delivery before deciding whether to stop, retry or flag an operation.
Action records should link commands, valve or interface states and actual received results. When raw material, container or sample identity changes, reconfirm shared paths and conditions permitting the next step. Completion of drive movement alone does not replace task acceptance.
Test detection, false alarms and recovery
Introduce controlled air aspiration, blockage, leakage and bubbles, and measure false alarms and recovery. Normal sensor output only describes the monitored state; it does not replace received-volume or method acceptance tests.
| Validation scenario | Measurement or observation | Interpretation and action |
|---|---|---|
| Fault detection | Introduce controlled faults and record false alarms | Evaluate detection rate and false alarms together |
| Release after recovery | Compare signals with the actual liquid state | Recheck affected deliveries even after signals return to normal |
Record test medium, configuration, installed path and operating sequence; present routine operating points and boundary results separately. Calculations support design discussions, component documentation checks models, and installed measurements confirm the actual task.
After an abnormality or maintenance, first identify which segment needs recovery
Normal air segments, viscosity changes and sampling delays may be misclassified. The controller determines task validity; sensors alone do not prove dose or assay results.
Retain current source, container identity, completed actions, valve or interface state and actual receiving information. Use the table to locate the stage that changed before deciding to retry, continue or restart. After recovery, recheck the relevant operating point before returning an uncertain action to the automatic cycle.
