Product Description
990-05-XX-01-00 MOD：289549-17 Bently Nevada 990 Series 2-wire Proximity Transmitter
Engineered with a 2-wire, loop-powered architecture, the 990-05-XX-01-00 MOD: 289549-17 transmitter seamlessly integrates an internal Proximitor sensor to output a standard 4-20 mA proportional radial vibration signal. It eliminates the critical technical pain point of needing a separate proximity sensor rack, allowing direct connection to an OEM control system or DCS. Backed by an optimized design for narrow spaces, it is the definitive choice for small target monitoring on centrifugal air compressors, pumps, motors, and fans.
Real-World Application Case Study
Project: Centrifugal Compressor OEM Skid Integration
Location: Indonesia (2025 Deployment)
Application: This exact model was successfully deployed for a manufacturing plant in Indonesia in 2025, operating flawlessly under tropical humid conditions. Installed onto space-restricted skid packs using integrated 35 mm DIN rails, the transmitters process tight-clearance radial vibration measurements from the high-speed shafts and feed them as raw 4-20 mA data straight to the central control loop.
Custom Product FAQ
Q: Why does this transmitter have a BNC jack if it outputs a 4-20 mA current loop?
A: The coaxial BNC connector provides an unfiltered, raw dynamic voltage output (PROX OUT). While the 4-20 mA loop sends an averaged peak-to-peak amplitude back to your control PLC, field technicians can hook a portable machinery analyzer up to the BNC port to check real-time gap voltages and waveform orbits during a shutdown.
Q: Can this 990 transmitter be used with standard 3300 XL 8mm probes?
A: No. The 990 transmitter internal circuits are tuned exclusively to balance the lower electrical capacitance of the 3300 NSv (Narrow Side View) probe and extension line family. Wiring an 8mm probe to it will cause significant tracking errors and break calibration compliance.
Q: What is the maximum distance the 4-20 mA wire loop can run?
A: Because it uses an industry-standard 2-wire 4-20 mA analog loop, the current signal can be transmitted over long distances—often up to several hundred meters depending on the loop power supply voltage (accepts +12 to +35 Vdc) and line resistance—without signal attenuation.
