Product Introduction
The BENTLY 190501-12-00-CN is a low-frequency piezoelectric velocity sensor built for continuous machinery protection. It specifically targets slow-speed rotating equipment like cooling fans and gearboxes.
Unlike standard velocity sensors, this unit captures frequencies down to 1.5 Hz. This allows it to accurately monitor machines operating as slowly as 90 rpm without signal attenuation.

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
❗ Firmware Mismatch: Newer monitor modules may require updated sensor calibration constants. Verify compatibility with your 3500/42M or 1900/65A monitor.
❗ DIP Switch / Jumper Misconfiguration: Factory defaults rarely match field settings. Always check bus termination resistors and sensor type jumpers on the terminal block.
❗ Terminal / Cable Incompatibility: Pin definitions can change between revisions. Always verify shield grounding at the third terminal block to prevent signal noise.
❗ Power Supply Mismatch: Calculate total rack power requirements carefully. Always include a 20% headroom margin for transient loads during startup.
❗ 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.
