Sensitivity & Measurement Range

The 200350-12-00-00 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 entire measurement range. For example, a 10 g peak vibration produces approximately 1000 mV output. The Bently Nevada 200350-12-00-00 connects directly to standard IEPE monitor inputs without any 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.

Adhesive Mounting with Option 12

The 12 mounting stud option provides an M8 x 1.25 adhesive stud mount. This mounting method uses epoxy or cyanoacrylate adhesive for installation. Adhesive mounting works exceptionally well on curved or irregular machine surfaces. The M8 x 1.25 thread matches metric standards common on European and Asian equipment. For temporary testing or permanent installation, adhesive studs offer great flexibility. This method leaves no permanent threads in the machine casing. The 200350-12-00-00 removes cleanly when the testing period ends. For applications where drilling is not permitted, adhesive mounting proves invaluable.

Physical Construction

The 200350-12-00-00 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 machine 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 200350-12-00-00 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 200350-12-00-00 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 200350-12-00-00.

1. Clean the mounting surface thoroughly with isopropyl alcohol.

2. Apply epoxy or cyanoacrylate adhesive to the M8 stud base.

3. Press the stud firmly against the surface for 30 seconds.

4. Allow the adhesive to cure fully per the manufacturer's instructions.

5. Thread the sensor onto the stud using the 1/4-28 female thread.

6. Tighten to 2 to 5 ft-lb (2.7 to 6.8 N-m) maximum torque.

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 200350-12-00-00 requires a clean, flat surface for proper adhesive bonding. Do not exceed 5 ft-lb mounting torque. The sensor case is electrically isolated, so external grounding is not required. For permanent installations, consider threaded mounting instead of adhesive.

Common FAQs

1. What is the sensitivity of the 200350-12-00-00?

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 200350-12-00-00 provides excellent signal-to-noise ratio for machinery protection systems without any external amplification.

2. What is the purpose of the M8 adhesive stud on the 200350-12-00-00?

The M8 x 1.25 adhesive stud attaches to machine surfaces using epoxy or cyanoacrylate. This method works well on curved or irregular surfaces where drilling is not permitted. For temporary testing, the stud removes cleanly after use. For permanent installations, the 200350-12-00-00 with adhesive mount provides a non-invasive attachment solution.

3. What is the operating temperature range for the 200350-12-00-00?

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 200350-12-00-00 performs reliably without special cooling.

4. Can I use the 200350-12-00-00 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 200350-12-00-00 withstands these harsh conditions. However, ensure the electrical connector remains properly mated and sealed.

5. What approvals does the 200350-12-00-00 carry?

The 00 agency approval option indicates no certifications are required for this model. This sensor lacks CSA, ATEX, and IECEx approvals. For non-hazardous area installations only, the 200350-12-00-00 works perfectly. Hazardous area applications require a different approval option code such as 05 or CN.
