Quick Detail

Description

The 990-08-XX-01-CN MOD 163930-02 Vibration Transmitter is a two-wire, loop-powered device designed for automated machinery monitoring. The 990-08-XX-01-CN MOD 163930-02 Vibration Transmitter accepts a 3300 NSv proximity probe and extension cable, converting shaft motion into a 4–20 mA signal for PLC and DCS systems. With a full-scale range of 0–8 mils pp (0–200 μm pp) and a linear measurement span of 0.25–1.65 mm, the 990-08-XX-01-CN MOD 163930-02 Vibration Transmitter supports vibration tracking on compressors, pumps, motors, and fans.

Powered by +12 to +35 Vdc and allowing up to 1,000 Ω loop resistance, the 990-08-XX-01-CN MOD 163930-02 Vibration Transmitter installs on a 35 mm DIN rail with a 7 m system length. Operating from −35°C to +85°C, the 990-08-XX-01-CN MOD 163930-02 Vibration Transmitter outputs dynamic vibration and gap voltage through a 10 kΩ PROX OUT connection for diagnostics and alarm logic.

Applications

Monitor centrifugal compressor shaft vibration
Using the 0–8 mils pp (0–200 μm pp) range, 990-08-XX-01-CN MOD 163930-02 Vibration Transmitter sends a proportional 4–20 mA signal to PLC or DCS racks. The 0.25–1.65 mm linear measurement span allows operators to read shaft motion in real time and trigger trip logic before the rotor contacts the bearing housing.

Measure pump bearing movement
When connected to a 3300 NSv probe, 990-08-XX-01-CN MOD 163930-02 Vibration Transmitter converts eddy-current displacement into loop current. With +12 to +35 Vdc supply and 1,000 Ω loop resistance, long control cables can run directly to control panels in pump stations without additional signal conditioners.

Track motor rotor position during start and stop
The dynamic PROX OUT output of 990-08-XX-01-CN MOD 163930-02 Vibration Transmitter provides vibration waveform and gap voltage. Maintenance staff can compare waveform amplitude during acceleration and coast-down to identify rotor rub or misalignment.

Send fan vibration data to plant alarm system
Installed on a 35 mm DIN rail, 990-08-XX-01-CN MOD 163930-02 Vibration Transmitter delivers a continuous 4–20 mA vibration signal to distributed I/O modules. At 23 mA current limiting, the control card receives safe current even if the probe cable loosens.

Specifications

Competitive Advantage

Output direct 4–20 mA signal to control system
990-08-XX-01-CN MOD 163930-02 Vibration Transmitter eliminates external signal converters. The transmitter directly scales shaft displacement to a standard loop current, so one analog input channel can immediately read machine vibration.

Operate in hot and cold equipment areas
With an operating range of −35°C to +85°C and storage down to −52°C, 990-08-XX-01-CN MOD 163930-02 Vibration Transmitter works near compressors, outdoor skids, and ventilation systems where cabinet heaters or coolers are limited.

Allow long cable routing inside plant
The 7.0 m transducer system length and 1,000 Ω allowable loop resistance enable 990-08-XX-01-CN MOD 163930-02 Vibration Transmitter to transmit vibration current through extended wiring to remote control rooms without signal attenuation concerns.

Provide diagnostic waveform output
Through the 10 kΩ PROX OUT connection, 990-08-XX-01-CN MOD 163930-02 Vibration Transmitter supplies raw vibration waveform and gap voltage for portable analyzers. Technicians can verify probe gap and shaft condition without shutting down the machine.
