Description
Product Introduction
The Vibro-Meter VM600 MPC4 provides real-time machinery protection by continuously monitoring shaft vibration, axial position, and dynamic pressure across high-value rotating equipment. Placed within a standard 19-inch rack, it processes raw signals to trip emergency shutdown loops before mechanical damage occurs.
Facilities choose the Vibro-Meter VM600 MPC4 when critical turbomachinery requires API 670 compliance and fast 20 ms trip execution. With 4 dynamic channels and 2 phase-reference inputs, it processes complex vibration metrics onboard, eliminating reliance on external host software during active plant transients.
Key Selling Points & Differentiators
- Dual tachometer processing enables tracking order-derived vibration during machine run-up and coast-down phases without signal aliasing.
- Every surplus card completes a 5-point engineering inspection including 500 V megger isolation checks and a 24-hour continuous burn-in test.
- Features active line-fault monitoring (OK meter circuit) that distinguishes real vibration spikes from transducer cable breaks, preventing false emergency trips.
- Not recommended for installation without the matching IOC4T rear input/output module and proper backplane keying.
- Fully compliant with API 670 standards for machinery protection systems.
Standard Quality Control Procedure
To ensure immediate field operational readiness, every Vibro-Meter VM600 MPC4 unit follows a strict 5-step quality verification process:
- Incoming Inspection: Verification of physical documentation, visual inspection for PCB copper track oxidation or connector pin wear, and serial number cross-referencing against manufacturer production records.
- Live Functional Test: Insertion into a dedicated VM600 test rack. The card undergoes power-on self-test checks, backplane bus handshake validation, 0–10 V and 4–20 mA signal injection across all 4 dynamic channels, speed input signal tracking, and a 24-hour continuous burn-in run with thermal tracking. Full test reports and video evidence are provided upon request.
- Electrical Parameter Tests: Insulation resistance evaluation using a 500 V megger (>10 MΩ target) between logic power planes and chassis ground, alongside supply voltage stability measurements.
- Firmware / Configuration Verification: Digital readout and recording of onboard DSP firmware builds (e.g., V3.1.0) and hardware jumper matrix settings.
- Final QC + Packaging: Final engineering sign-off, sealing inside anti-static ESD bags, multi-layer bubble wrap protection, heavy-duty carton packaging, and attachment of a dated “QC Passed” label. Passed the above checks; verified functional at time of test.
