The Bently 990-16-XX-01-CN/00 vibration transmitter, with the suffix 05 or CN, has been officially certified explosion-proof by the China National Instrument Explosion-Proof Safety Supervision and Inspection Center. It is suitable for industrial sites requiring explosion-proof protection, such as chemical plants. This cable, part of the Bently 3300 XL NSv series, is a standard 4.5-meter extension cable. It is primarily designed for vibration monitoring of large and medium-sized rotating machinery, such as centrifugal air compressors, small pumps, fans, steam turbines, compressors, fans, water pumps, coal mills, gearboxes, and motors. It is widely used in industries such as steel, power generation, metallurgy, chemicals, and petrochemicals.
This vibration transmitter is primarily intended for original equipment manufacturers (OEMs) who require a simple 4-20 mA proportional vibration signal for their machinery control systems. As a two-wire loop-powered device, the Bently 990-16-XX-01-CN/00 converts vibration signals into a proportional 4-20 mA standard current signal and transmits it to equipment control systems such as PLCs or DCSs, providing reliable support for condition monitoring and system protection of industrial rotating machinery.
The 990-16-XX-01-CN/00 offers the following features:
Integrated proximity sensor, eliminating the need for external units;
Non-isolated "PROX OUT" and "COM" terminals and a coaxial connector provide dynamic vibration and gap voltage output signals for diagnostics;
Zero and span potentiometers are located below the transmitter label, enabling loop adjustment without interfering with each other;
A test input allows for quick verification of loop signal output using a function generator;
A "Not OK" circuit prevents high output or false alarms caused by probe failure or loose connections;
Standard DIN rail clips or panel mounting screws provide flexible and easy installation;
Potted construction withstands high humidity environments (up to 100% condensation);
Compatible with the 3300 NSv proximity probe, it is suitable for installation in tight spaces and limited clearances.
This transmitter is compatible with Bentley 3300 XL vibration sensor probes, including the 330101, 330902, 330103, 330104, 330105, and 330106 models. Extension cables are available in 5- and 9-meter system lengths.
