200350-11-00-CN | Bently Nevada 100 mV/g Accelerometer

Introduction to the 200350-11-00-CN Accelerometer

When machinery vibration threatens uptime, the 200350-11-00-CN from Bently Nevada provides reliable monitoring. This accelerometer is part of the 200350 series, designed for industrial vibration measurement. It offers a sensitivity of 100 mV/g ±20% and a measurement range of ±50 g, making it suitable for a wide range of rotating equipment.

Key Features and Technical Specifications

• Sensitivity: 100 mV/g ±20% (10.2 mV/m/s² ±20%)
• Frequency Range: 30–600,000 cpm (0.5–10,000 Hz) ±3 dB
• Measurement Range: ±50 g
• Output Bias Voltage: 8 to 12 VDC
• Excitation Voltage: 18 to 28 VDC
• Constant Current Excitation: 2 to 20 mA
• Operating Temperature: -65°F to +250 ºF (-54°C to +121 ºC)
• Enclosure Rating: IP68
• Housing Material: Stainless Steel
• Sealing: Welded Hermetic

The ceramic shear sensing element ensures accurate readings across a broad frequency range. The IP68 rating allows operation in condensing humidity and non-submerged conditions. With a mounted resonant frequency of 1500 kcpm (25 kHz), this sensor captures high-frequency vibrations effectively.

Installation and Setup Guide

Mount the 200350-11-00-CN using the M6x1 adhesive stud mount. The mounting thread is 1/4-28 female. Apply a mounting torque between 2 to 5 ft-lb (2.7 to 6.8 N-m). The electrical connector is a 2-pin Mil-C-5015 type located at the top. Ensure the excitation voltage stays between 18 and 28 VDC with constant current from 2 to 20 mA. Allow 2.0 seconds settling time within 1% of bias after power-up.

Maintenance and Reliability Tips

Periodically inspect the welded hermetic seal and stainless steel housing for damage. The IP68 rating protects against dust and water ingress, but verify the connector is properly mated. Check output bias voltage regularly; it should remain between 8 and 12 VDC. For long-term reliability, follow the manufacturer’s guidelines for periodic calibration and verification.
