Bently Nevada 200355-10-00-00 Accelerometer Overview

The Bently Nevada 200355-10-00-00 is a 200350 series accelerometer made in the USA. This sensor measures vibration on industrial rotating machinery. The mounting stud option 10 provides a 1/4-28 adhesive stud mount for easy installation. Tolerance option 00 delivers 100 mV/g ±20% sensitivity. Agency approval option 00 indicates no hazardous area certifications. Therefore, this version suits general industrial environments only. The sensing element uses ceramic material with shear geometry for excellent stability.

Sensitivity & Frequency Response

The Bently Nevada 200355-10-00-00 offers reliable sensitivity specifications. Sensitivity is 100 mV/g ±20% (10.2 mV/m/s² ±20%) for standard monitoring systems. Frequency range at ±3 dB spans 30-600,000 cpm (0.5-10,000 Hz) . This wide range covers most machinery fault frequencies. Measurement range reaches ±50g for high-amplitude applications. Transverse sensitivity is less than ≤7% for minimal cross-axis error. Amplitude linearity holds at ±1% for accurate measurements across the full range. Mounted resonant frequency is 1500 kcpm (25 kHz) for high-frequency response capability.

Now consider the electrical noise performance. Broadband electrical noise from 1-10 kHz measures 350 μg (3,434 μm/s²) . This low noise floor enables detection of small vibration changes. Output bias voltage ranges from 8 to 12 VDC for standard interface compatibility. Excitation voltage must be 18 to 28 VDC for proper sensor operation. Constant current excitation requires 2 to 20 mA from the power supply. Settling time within 1% of bias is only 2.0 seconds for fast startup.

Output & Impedance Specifications

The Bently Nevada 200355-10-00-00 provides consistent output characteristics. Output impedance is less than 150 ohms for driving long cables. Discharge time constant reaches ≥0.3 seconds for low frequency response. Electrical isolation between case and circuit exceeds 10⁸ ohms. Consequently, grounding the case does not affect measurement quality. The sensing element uses ceramic material with shear geometry for excellent temperature stability. This shear design minimizes base strain sensitivity compared to compression designs.

Environmental & Mechanical Specifications

The Bently Nevada 200355-10-00-00 operates in demanding environmental conditions. Operating temperature range spans -54°C to +121°C (-65°F to +250°F) . Shock survivability reaches 5,000 g peak for rugged durability. Relative humidity tolerance goes to 100% condensing, non-submerged conditions. Enclosure rating is IP68 for complete dust and water immersion protection. The housing is welded hermetic for permanent sealing.

Now examine the mechanical construction details. Hex size is 11/16 inch (1.8 cm) for wrench access. Height measures 1.65 inches (4.24 cm) from mounting surface to connector top. Weight is only 0.051 kg for minimal added mass on machinery. Housing material is stainless steel for excellent corrosion resistance. Sealing is welded hermetic to prevent moisture ingress. Electrical connector is 2-pin Mil-C-5015 for reliable field connections. Electrical connection position is top mounted for easy access. Mounting thread is 1/4-28 female for stud or screw attachment. Mounting torque maximum ranges from 2 to 5 ft-lb (2.7 to 6.8 N-m) .

Installation Guidelines

Follow these steps to install the Bently Nevada 200355-10-00-00 correctly. First, clean the mounting surface thoroughly to remove oil and debris. Second, apply adhesive to the 1/4-28 stud per manufacturer instructions. Third, attach the stud to the clean surface and allow curing. Fourth, thread the accelerometer onto the stud by hand until snug. Fifth, tighten the sensor to 2 to 5 ft-lb (2.7 to 6.8 N-m) maximum torque. Finally, connect the 2-pin Mil-C-5015 connector until fully seated.

Do not exceed 5 ft-lb of mounting torque to avoid damage. Use only approved adhesive for the stud mount application. Also, avoid routing sensor cables near high voltage sources. The 200355-10-00-00 requires 18-28 VDC excitation with 2-20 mA constant current. Verify output bias voltage reads between 8 and 12 VDC after connection.

Package Contents

Frequently Asked Questions (FAQ)

1. What is the difference between shear and compression accelerometers?
The 200355-10-00-00 uses ceramic shear sensing geometry. Shear designs offer better temperature stability and lower base strain sensitivity than compression designs.

2. Can this sensor be used in submerged applications?
Yes. The Bently Nevada 200355-10-00-00 has IP68 rating and welded hermetic sealing. However, the connector must remain properly mated for full submersion protection.

3. What excitation current does this accelerometer require?
The 200355-10-00-00 requires constant current excitation between 2 and 20 mA. Standard industrial IEPE power supplies typically provide 4-10 mA.

4. Is the sensor case electrically isolated?
Yes. Electrical isolation between the case and circuit exceeds 10⁸ ohms. Therefore, grounding the sensor case does not affect the measurement signal.

5. What is the settling time after power application?
The 200355-10-00-00 settles to within 1% of bias voltage within 2.0 seconds. Consequently, measurements are stable shortly after power-up.
