  • INQUIRY

BENTLY NEVADA 190501-18-00-00 is a proximitor (also known as a probe driver) belonging to the 1900/65A Series of high-performance eddy current sensor systems.

Its core function is to supply power to the eddy current probe and process the weak signal returned by the probe, converting it into a standardized DC voltage signal proportional to the gap voltage. This signal is ultimately used for precise measurement of shaft vibration and shaft position in rotating machinery.

Key Features & Functions

Signal Conversion & Drive:

Provides the necessary power to the connected eddy current probe.

Receives signals detected by the probe resulting from changes in the electromagnetic field due to the proximity of a metal conductor (e.g., machine rotor shaft).

Linearizes the weak RF signal and converts it into a easily transmittable and recognizable gap voltage signal ranging from -2V DC to -18V DC, along with a buffered output signal of -4V DC to -20V DC.

System Compatibility:

It is a standard component of the 3300 XL 8mm System and 3300 XL 11mm System.

Typically used in conjunction with 3300 XL 8mm probes and 3300 XL extension cables to form a complete measurement loop.

High-Reliability Design:

Bently Nevada products are renowned for their high reliability in harsh industrial environments. This proximitor is designed for critical mechanical equipment such as steam turbines, gas turbines, compressors, and pumps.

Provides stable and accurate measurements, essential for predictive maintenance and mechanical protection.

Foundation for Mechanical Protection:

The vibration and position signals generated by this unit are sent to subsequent monitors (e.g., 3300 monitors) and compared with preset alarm values. When vibration or displacement exceeds safe limits, the system triggers an alarm or shutdown signal to prevent serious damage to large rotating equipment.
