Description

The 990-10-XX-01-05 MOD: 163930-01 is a loop-powered 2-wire vibration transmitter engineered to process raw signals from proximity probe systems and output a proportional 4-20 mA analog current loop directly to control architectures. This integration eliminates the need for separate proximitor sensors and centralized monitor racks, allowing for a simplified machinery protection interface on compact rotating assets. The device monitors peak-to-peak casing or shaft vibration to safeguard original equipment manufacturer (OEM) packages against mechanical faults. Optimized for confined physical spaces, the system utilizes specialized narrow-profile transducers to deliver reliable dynamic measurements. The MOD: 163930-01 designation indicates a specific factory modification tailored to adjust internal circuit gain, tune frequency response curves, or match the input impedance requirements of targeted industrial control loops.

Features

Integrated proximitor and transmitter functionality within a single potted enclosure.
Directly outputs a 4-20 mA DC signal proportional to overall vibration displacement.
Dedicated non-isolated dynamic signal terminals (PROX OUT and COM) for field analysis.
Not OK / Signal Defeat circuitry to prevent erroneous control system trips during sensor faults.
Fully encapsulated electronics providing resistance to 100% condensing humidity.

Applications

OEM centrifugal air compressor protection packages.
Small industrial pump vibration monitoring.
Electric motor shaft displacement tracking.
Industrial cooling fan and blower machinery protection loops.

Installation Guidelines

DIN Rail Mounting: Securely latch the integrated mounting clip onto a standard 35 mm DIN rail inside a dust-tight enclosure.
Shielding and Noise Suppression: Connect the cable shield wires to the instrument ground at the PLC/DCS cabinet only. Maintain shield continuity through any intermediate junction boxes without grounding the shield locally at the transmitter.
Transducer Gap Adjustment: Follow standard engineering procedures to adjust the initial mechanical gap of the 3300 NSv probe using the dynamic voltage output from the PROX OUT terminal prior to finalizing installation.
Conduit and Cable Routing: Separate field wiring from high-power electrical cabling to mitigate electromagnetic interference that can distort the low-level transmitter inputs.

Compliance and Certifications

CSA Division 2
ATEX Zone 0 / Zone 2
ABS Marine Type Approval

Key Features:

#Vibration Transmitter

What is the primary measurement range of this transmitter?

The primary full-scale measurement range configured for this device is 0-10 mils peak-to-peak, which equates to 0-250 um peak-to-peak displacement.

Which proximity probe system is compatible with this model?

This transmitter is engineered specifically to interface with the Bently Nevada 3300 NSv narrow side view proximity probe and its associated extension cables.

How does the Not OK circuit protect the control system?

The circuit continuously checks probe and cable integrity. If a loose connection or open circuit is found, the transmitter locks the loop output to avoid false alarms or high-current trip states.

Can I read raw vibration data directly from the field module?

Yes, you can connect a dynamic signal analyzer or oscilloscope to the non-isolated PROX OUT and COM terminals to observe the unconditioned voltage waveform and check the gap status.
