Sensitivity & Measurement Range

The 200350-02-00-CN delivers 100 mV/g output with ±20% tolerance. This high sensitivity captures small vibration signals effectively. Measurement range extends to ±50 g for high-energy machinery monitoring. Amplitude linearity holds at ±1% across the measurement range. For example, a 10 g peak vibration produces approximately 1000 mV output. The Bently Nevada 200350-02-00-CN connects directly to standard IEPE monitor inputs without additional amplification.

Frequency Response Characteristics

Frequency response spans 30 to 600,000 cpm (0.5 to 10,000 Hz). The ±3 dB tolerance applies across this entire operating range. Low-frequency rolloff begins below 30 cpm for this sensor. High-frequency response extends beyond 10 kHz but with increasing attenuation. Mounted resonant frequency reaches 1500 kcpm (25 kHz). Therefore, the sensor avoids resonance interference within its specified measurement band. For most rotating machinery from 120 to 600,000 cpm, this frequency range proves more than adequate.

Mounting Stud Option 02

The 02 mounting stud option provides a ¼-28 to M8 x 1.25 BeCu adapter. Beryllium copper (BeCu) offers excellent conductivity and corrosion resistance. This adapter converts the standard 1/4-28 female thread to M8 x 1.25 metric. Consequently, the 200350-02-00-CN mounts directly onto metric M8 studs commonly found on European and Asian machinery. For imperial mounting systems, choose a different stud option instead. The BeCu material also provides good electrical conductivity for proper grounding.

Country-Specific Approvals (Option CN)

The CN approval option indicates country-specific certifications for the 200350-02-00-CN. These approvals meet local regulatory requirements for specific nations. For example, certain countries have unique electromagnetic compatibility or safety standards. The CN option serves markets with national certification requirements. Consult Bently Nevada documentation for exact countries covered by this option. For global applications without country-specific needs, order the 00 approval option instead. The 200350-02-00-CN satisfies local compliance for its intended destination.

Physical Construction

The 200350-02-00-CN uses a stainless steel housing for excellent corrosion resistance. A welded hermetic seal prevents moisture ingress permanently. The shear ceramic sensing element provides outstanding temperature stability. Height measures 1.65 inches (4.24 cm) for standard form factor compatibility. Hex size measures 11/16 inch (1.8 cm) for installation tools. Weight totals only 0.051 kg for minimal mass loading on machinery surfaces. The 2-pin Mil-C-5015 connector sits on the top face for easy access. Electrical isolation between case and circuitry exceeds 10⁸ ohms. Consequently, ground loops do not affect measurement quality at all.

Environmental Robustness

The 200350-02-00-CN survives extreme operating conditions reliably. Temperature range spans -54°C to +121°C (-65°F to +250°F). IP68 enclosure rating protects against dust and continuous immersion. Shock survivability reaches 5,000 g peak for machine transient events. Relative humidity tolerance reaches 100% condensing without any damage. The welded hermetic seal ensures long-term reliability even in wet environments. For offshore platforms, marine vessels, and outdoor installations, this environmental protection proves absolutely essential.

Electrical Interface

The 200350-02-00-CN requires constant current excitation for proper operation. Excitation voltage spans 18 to 28 VDC for flexible power supply compatibility. Constant current ranges from 2 to 20 mA to suit various signal conditioners. Output bias voltage falls between 8 and 12 VDC under normal conditions. Settling time after power application reaches 2.0 seconds within 1% of final bias. Output impedance stays safely below 150 ohms for long cable runs. Discharge time constant measures at least 0.3 seconds for low-frequency response. Broadband electrical noise from 1 to 10 kHz stays below 350 μg (3,434 μm/s²). For this reason, the sensor provides exceptionally clean signals even at very low vibration levels.

Installation Guidelines

Follow these steps for proper installation of the 200350-02-00-CN.

1. Prepare a flat, clean mounting surface on the machine casing.

2. Apply a thin layer of coupling grease to improve high-frequency response.

3. Install the M8 x 1.25 stud into the machine mounting hole.

4. Thread the BeCu adapter onto the stud using the ¼-28 to M8 conversion.

5. Mount the sensor onto the adapter using the 1/4-28 female thread.

6. Tighten to 2 to 5 ft-lb (2.7 to 6.8 N-m) maximum torque. Do not exceed this value.

7. Connect the 2-pin Mil-C-5015 cable to the top connector.

8. Apply 18-28 VDC constant current excitation at 2-20 mA.

Note: The 200350-02-00-CN requires a clean, flat surface for proper frequency response. Do not exceed 5 ft-lb mounting torque. The sensor case is electrically isolated, so external grounding is not required. For country-specific approval documentation, contact Bently Nevada with your destination country.

Common FAQs

1. What is the sensitivity of the 200350-02-00-CN?

Sensitivity measures 100 mV/g ±20% (10.2 mV/m/s² ±20%). This standard sensitivity matches most industrial monitors perfectly. For a 1 g vibration, output reaches approximately 100 mV. The 200350-02-00-CN provides excellent signal-to-noise ratio for machinery protection systems without any external amplification.

2. What does the CN approval option mean for the 200350-02-00-CN?

The CN option indicates country-specific certifications rather than general approvals. Standard options like 00 carry no approvals. The CN option meets unique national standards for specific destination countries. Before ordering the 200350-02-00-CN, verify that CN approvals apply to your installation location. Contact Bently Nevada for the exact list of covered countries.

3. What is the purpose of the BeCu mounting stud on the 200350-02-00-CN?

Beryllium copper (BeCu) offers excellent electrical conductivity and corrosion resistance. This stud converts the 1/4-28 female thread to M8 x 1.25 metric. Consequently, the 200350-02-00-CN mounts directly onto metric M8 studs common on European and Asian machinery. For imperial mounting systems, order a different stud option instead.

4. What is the operating temperature range for the 200350-02-00-CN?

Operating temperature spans -54°C to +121°C (-65°F to +250°F). Storage temperature matches this same range. The welded hermetic seal prevents moisture ingress across this full range. For extreme high-temperature machinery like gas turbines, the 200350-02-00-CN performs reliably without special cooling.

5. Can I use the 200350-02-00-CN in continuous immersion applications?

Yes, the IP68 enclosure rating protects against continuous immersion. The welded hermetic seal prevents water ingress completely. Relative humidity tolerance reaches 100% condensing as well. For underwater or flood-prone installations, the 200350-02-00-CN withstands these harsh conditions. However, ensure the electrical connector remains properly mated and sealed.
