200350-12-00-CN | Bently Nevada 100 mV/g Accelerometer

Introduction to the Bently Nevada 200350-12-00-CN

When machinery vibration threatens uptime, the 200350-12-00-CN from Bently Nevada provides reliable, accurate data. This accelerometer is part of the 200350 series, designed for continuous condition monitoring in demanding settings. With a sensitivity of 100 mV/g ±20% and a measurement range of ±50 g, it captures both subtle and severe vibration events. The 200350-12-00-CN is built to withstand extreme conditions, from -65°F to +250°F, and is sealed to IP68 for use in condensing humidity.

Key Features & Technical Specifications

• Sensitivity: 100 mV/g ±20% (10.2 mV/m/s² ±20%) ensures consistent output.
• Frequency Range: 30–600,000 cpm (0.5–10,000 Hz) covers low to high frequencies.
• Measurement Range: ±50 g allows monitoring of normal and severe vibrations.
• Output Bias Voltage: 8 to 12 VDC provides stable baseline signal.
• Excitation Voltage: 18 to 28 VDC, with constant current 2 to 20 mA.
• Enclosure Rating: IP68 for protection against dust and prolonged immersion.
• Operating Temperature: -65°F to +250°F (-54°C to +121°C).
• Shock Survivability: 5,000 g pk ensures durability in harsh conditions.
• Housing Material: Stainless steel with welded hermetic sealing.
• Electrical Connector: 2-Pin Mil-C-5015 top-mounted for easy installation.

Real-World Applications

In rotating machinery like pumps, fans, and compressors, the 200350-12-00-CN excels at early fault detection. Its wide frequency range captures bearing wear and imbalance. The IP68 rating makes it ideal for washdown environments or outdoor installations. For example, a petrochemical plant can rely on this accelerometer to monitor critical pumps in humid, corrosive areas, reducing unplanned downtime.

Installation & Setup

Mount the 200350-12-00-CN using the M8x1.25 adhesive stud mount (included with the -12 option). Tighten to 2–5 ft-lb (2.7–6.8 N·m) maximum torque. Connect via the 2-pin Mil-C-5015 top connector. Ensure excitation voltage between 18 and 28 VDC with constant current 2–20 mA. Allow 2.0 seconds settling time after power-up for bias stabilization.

Maintenance & Reliability

Routinely inspect the cable and connector for damage. The stainless steel housing and welded hermetic seal resist corrosion and moisture ingress. With no moving parts, the ceramic shear sensing element offers long-term stability. Periodic verification of output bias voltage (8–12 VDC) confirms proper operation. For maximum reliability, follow the manufacturer's guidelines for periodic recalibration.
