Proximitor Sensor | 330100-50-02 | Bently Nevada

Technical Specifications

330100-50-02 is a Proximitor Sensor manufactured by Bently Nevada. This sensor is part of the 3300 XL Proximitor series, offering advanced capabilities for both static (position) and dynamic (vibration) measurements, making it an essential tool for accurately monitoring performance.

Features

Static and Dynamic Measurement: Supports both position and vibration monitoring. Measures target position for alignment and rotor tracking, while also detecting vibration issues such as imbalance, misalignment, and wear.

Ideal for Keyphasor and Speed Applications: Provides reliable Keyphasor signals for phase reference and accurate speed measurement, supporting rotor analysis and machinery protection.

Stable Output Across Wide Temperatures: Delivers accurate and consistent signals in harsh environments, maintaining reliable performance under significant temperature variations.

-02 Intrinsically Safe Explosion-Proof Control (Hazardous Area Installation)

Safety Barrier Configuration: When installed in Zone 2 or requiring connection to an intrinsically safe circuit, an intrinsically safe barrier must be connected in series.

Voltage Drop Compensation: Introducing a safety barrier will cause a voltage drop in the circuit. To ensure sufficient linear operating space for the preamplifier's internal circuitry, a stronger negative voltage is required at the power input, ideally between -23 Vdc and -26 Vdc (if the voltage is positive (-23.5 Vdc), the maximum linear range of the preamplifier may be reduced due to current limiting by the safety barrier).

Technical FAQ

Q: How is the 330100-50-02 different from the 330100-50-00 in hardware?

A: The circuitry and measurement performance are identical, including the sensitivity of 200 mV/mil. However, the 330100-50-02 housing carries hazardous-area certifications such as Ex ia / Class I, Div 1, and its internal electrical parameters comply with explosion-proof requirements.

Q: What special wiring requirements apply to 330100-50-02 in hazardous areas?

A: As an Intrinsically Safe (IS) device, it must be connected through a safety barrier (IS barrier) before interfacing with a 3500 or 3300 monitoring system. The barrier limits energy entering the hazardous area and prevents ignition from electrical sparks.

Q: Does using a safety barrier affect the power supply requirements of 330100-50-02?

A: Yes. Without a safety barrier, the unit operates on -17.5 Vdc to -26 Vdc. When a safety barrier is used, the supply voltage must be maintained between -23 Vdc and -26 Vdc. Voltages above -23.5 Vdc may reduce the linear measurement range.

Q: Is the 330100-50-02 prone to failure, and how can a fault be identified?

A: The Proximitor is generally reliable because it is a solid-state electronic device. The most common failures are caused by moisture or oil contamination in the high-frequency coaxial connector, or loose terminal wiring connections.
