BENTLY 330190-040-00-CN
Product Introduction
The BENTLY 330190-040-00-CN is a 4.0 m ETR extension cable designed for extreme heat zones. It reliably connects 330191 probes to proximitors in steam turbines and gas turbines.
Unlike standard 330130 cables, this unit withstands continuous exposure up to 260°C. The “-CN” suffix confirms compliance with specific Chinese regional market certifications and requirements.

Quality Control Process (Engineer’s Perspective)
- Incoming Verification: We check source traceability and verify serial numbers against anti-counterfeit databases. Visual inspection confirms no physical damage or connector corrosion.
- Live Functional Test: Power-on self-checks validate basic operation. We run continuous load tests exceeding 24 hours with temperature logging to ensure stability.
- Electrical Parameter Test: Insulation resistance is verified using a 500 V Megger, requiring >10 MΩ. Ground continuity is also strictly checked.
- Firmware Verification: We read and record internal firmware versions. DIP switch and jumper settings are photographed for future reference.
- Final QC & Packaging: The unit is sealed in an anti-static bag. A QC Passed label with the inspection date is applied before shipping.
Replacement Pitfall Guide
❗ Temperature Rating Confusion: Never substitute standard 330130 cables in ETR applications. Standard cables fail rapidly above 177°C, while this unit handles 260°C.
❗ System Length Mismatch: Ensure the probe (330191) plus this 4.0 m cable equals your proximitors rating. A 5.0 m system requires a 1.0 m probe and this 4.0 m cable.
❗ Cable Jacket Damage: Inspect for heat discoloration or brittleness during replacement. Even ETR cables degrade if clamped too tightly against hot piping.
❗ Connector Seating: ClickLoc connectors must be fully seated. High-temperature expansion can loosen connections over time, causing intermittent signal loss.
❗ ESD Damage: Use an anti-static mat during installation. Dry environments significantly increase electrostatic discharge risks to sensitive electronics.
Keep these in mind and you’ll cut 90% of rework time.

Compatibility Matrix & Benchmarks
- 330190-040-00-CN → 330190-040-00-05 : Direct — same cable, multi-agency approval vs. CN only
- 330190-040-00-CN → 330130-040-00-00 : Incompatible — standard temp (177°C) vs. ETR (260°C)
- 330190-040-00-CN → 330190-030-00-CN : Needs Adaptation — different length (3.0 m vs. 4.0 m)
- Signal Attenuation: < 0.5 dB over full 4.0 m length
- Thermal Stability: < 1% sensitivity shift at 260°C
