The Esaote CW5 Pencil/CW is a common candidate for repair rather than replacement. This page lists its typical failure modes, self-checks you can run, and the details a repair lab needs from you.
| Manufacturer | Esaote |
|---|---|
| Model | CW5 Pencil/CW |
| Probe type | Pencil/CW array |
| Compatible systems | Esaote MyLab 20 Plus, Esaote MyLab 30 CV, Esaote MyLab 40, Esaote MyLab 50, Esaote MyLab ClassC, Esaote MyLab Five |
In service the CW5 Pencil/CW is most often found on Esaote MyLab 20 Plus, Esaote MyLab 30 CV, Esaote MyLab 40, Esaote MyLab 50, Esaote MyLab ClassC and other listed systems. Console-side settings and module revisions still vary, so the exact system build is part of any assessment.
For CW pencil probes such as the CW5 Pencil/CW, the short parts list means diagnosis is quick: cable continuity, connector condition and crystal output cover most failures.
Common failure modes for the CW5 Pencil/CW
Match what you are seeing against the table below. The right-hand column reflects how faults of this kind typically assess – the actual verdict always depends on the individual probe.
| What you see | Likely cause | Typically repairable? |
|---|---|---|
| Connector lock broken or hardware missing | Mechanical damage to the connector shell | Usually repairable |
| Bent, broken or corroded connector pins | Mechanical damage from forcing or dropping the connector | Usually repairable |
| Large areas of the array not firing | Extensive element loss across the acoustic stack | Usually not economical |
| Intermittent signal that changes as the cable moves | Broken internal conductors in the cable | Case by case |
| Dark bands or dropout lines in the image | Element dropout, or a conductor break inside the cable | Case by case |
| Split seams or impact marks on the probe body | A drop or knock; housings are routinely replaced or resealed | Usually repairable |
| Air pockets or peeling visible on the acoustic lens | Lens delamination from the acoustic stack | Usually repairable |
Check these before you ship the probe
- Run the system’s built-in probe test or element check if your console provides one.
- Compare penetration and uniformity against a known-good probe on the same preset.
- Inspect the lens face under good light for cuts, bubbles, lifting edges or discoloration.
- Photograph the complete manufacturer label – the exact revision matters for parts compatibility.
- Check the strain reliefs at both ends for splits, stiffness or separation from the cable.
Repair, exchange or replace — which applies to your CW5 Pencil/CW
Three paths apply to a failing CW5 Pencil/CW: repair (typical for lens, housing, cable and connector damage), exchange (fastest route back to scanning) or replacement (when the acoustic stack is too far gone). The deciding factors are how much of the array still fires, whether the housing is intact and what downtime costs you. Each probe is judged on its actual condition.
What we need to quote your CW5 Pencil/CW repair
- A clear photo of the complete manufacturer and model label on the probe
- A description of the fault: what you see on screen and when it started
- The ultrasound system (console) the probe is used with
- Screenshots or photos of the image problem, if the fault is visual
- Photos of any physical damage – lens, housing, cable or connector
Images shown are representative and are not photographs of an individual unit. Nothing on this page claims OEM authorization or guarantees universal fit. Whether a specific CW5 Pencil/CW can be repaired, and on what terms, is confirmed in writing once the probe has been assessed.
