21747-040-01 Bently Nevada 4-Meter 7200 Series Extension Cable

Product Overview

The Bently Nevada 21747-040-01 is a specialized 4-meter proximity transducer extension cable designed for critical machinery protection systems. This component interfaces directly with 7200 series monitoring equipment to deliver dependable data transmission.

Functional Description

This extension cable serves as a crucial link between proximity probes and Proximitor sensors. By protecting low-voltage signals from electrical noise, the cable preserves data integrity across its entire 4-meter span. It supports non-contact displacement measurements by accurately transmitting the gap-to-voltage variations from the sensor tip to the control room monitor. Consequently, operators receive precise readings of static and dynamic distances between the probe and the observed target area.

Technical Characteristics

• System Compatibility: Designed specifically for Bently Nevada 7200 series proximity transducer systems.
• Probe Integration: Works seamlessly with both 5mm and 8mm proximity probes.
• Frequency Range: Supports consistent signal transmission from 0 Hz (DC) to 10 kHz.
• Linear Range: Maintains calibration accuracy over a standard 80 mil (2 mm) linear measuring range.
• Industrial Compliance: Helps machinery monitoring setups conform to API 670 standards for vibration monitoring.
• Environmental Shielding: Incorporates advanced noise-rejection construction to counteract electromagnetic interference in heavy industrial zones.
