A failing Acuson CH5-2 does not always mean buying a new probe. Use the fault table below to match what you are seeing on screen to a likely cause, then check what a repair assessment would need.
| Manufacturer | Acuson |
|---|---|
| Model | CH5-2 |
| Probe type | Convex array |
| Compatible systems | Acuson CV70, Acuson Sonoline, Acuson X150, Acuson X300 |
The CH5-2 typically pairs with Acuson CV70, Acuson Sonoline, Acuson X150, Acuson X300; the same fault can present differently between console revisions, which is why the host system is asked for with the quote details.
On convex probes such as the CH5-2, the curved acoustic window wears unevenly under pressure-heavy scanning; lens condition is the first thing to check when image quality drops.
Common failure modes for the CH5-2
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? |
|---|---|---|
| Bent, broken or corroded connector pins | Mechanical damage from forcing or dropping the connector | Usually repairable |
| Strain relief separated, split or stiff | Flex fatigue where the cable meets the probe or connector | Usually repairable |
| Bubbles or lifting at the lens face | The lens separating from the acoustic stack underneath | Usually repairable |
| Large areas of the array not firing | Extensive element loss across the acoustic stack | Usually not economical |
| Visible nicks, grooves or staining on the lens surface | Mechanical wear or disinfectant damage to the lens | Usually repairable |
| Dark bands or dropout lines in the image | Failed transducer elements or a broken conductor in the cable | Case by case |
| Depth performance clearly below what this probe used to deliver | Ageing elements or lens delamination reducing acoustic output | Case by case |
Check these before you ship the probe
- Inspect the lens face under good light for cuts, bubbles, lifting edges or discoloration.
- Flex the cable gently along its length while imaging – intermittent dropout points to broken conductors.
- Compare penetration and uniformity against a known-good probe on the same preset.
- Check the strain reliefs at both ends for splits, stiffness or separation from the cable.
- Examine the connector for bent or corroded pins, cracks and a working locking mechanism.
Repair, exchange or replace — which applies to your CH5-2
Three paths apply to a failing CH5-2: 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 CH5-2 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 CH5-2 can be repaired, and on what terms, is confirmed in writing once the probe has been assessed.
