Hardware Specifications

Mechanical Monitoring and Signal Integrity

The 350800 sensor operates as a critical component in environmental safety loops. While primarily distinct from rotor dynamics monitoring, its integration into the Bently Nevada platform ensures that environmental conditions are correlated with machinery performance. The sensor output is calibrated to 15 mV / % LEL, requiring precise signal conditioning to prevent false alarms. Cross-talk suppression and noise rejection are implemented within the sensor head to maintain signal stability in high-EMI environments. Validation of the signal output against specified calibration gases is necessary to ensure the integrity of the safety monitoring chain.

Field Installation Guidelines

• Flameproof Mounting: The sensor enclosure is flameproof; ensure all thread engagements and cable entries are tightened according to local hazardous area installation standards.
• Orientation: Install the sensor in a vertical, downward-facing orientation to prevent debris accumulation on the sensing element.
• Grounding: Secure the metal housing to a verified earth ground point to minimize static buildup and electromagnetic interference.
• Calibration Access: Provide adequate clearance for routine calibration gas application and sensor maintenance.

Frequently Asked Questions

• What is the response time of this gas sensor?

  The response time is dependent on gas concentration and airflow; refer to the technical manual for specific T90 response time constants under standard testing conditions.

• Is the sensor interchangeable with the 350800-01-006-00?

  Yes, this part is the official revision/replacement. Compatibility should be verified against the host system's input range and configuration settings.

• Does this sensor require external power?

  The sensor operates on a low-voltage DC loop provided by the host monitoring system; ensure loop voltage is within the rated range.

• How is the sensor calibrated?

  Calibration requires a certified reference gas and an application kit to maintain accuracy; follow the prescribed field calibration intervals.

• Can it be used in high-dust environments?

  Yes, the IP66/IP67 enclosure rating provides protection against dust ingress, though excessive buildup on the sensor head may affect gas diffusion.

• Does the sensor output provide a fail-safe signal?

  The sensor loop current or voltage levels are designed to distinguish between normal gas readings, sensor faults, and signal over-range conditions.

• What is the impact of moisture on the sensor?

  While the sensor is IP-rated, direct liquid water contact on the sensing element can temporarily inhibit gas detection; ensure proper drainage.

• Can the sensor detect multiple gas types?

  The calibration is specific to target gas types; consult the documentation to confirm the target gas for the 15 mV / % LEL sensitivity setting.
