Quick Detail

Description

990-10-XX-01-00 MOD 283278-01 Vibration Transmitter is a two-wire loop-powered device designed for automation machinery monitoring. 990-10-XX-01-00 MOD 283278-01 Vibration Transmitter accepts a 3300 NSv proximity probe and 7.0 m extension cable, then converts shaft displacement into a 4–20 mA control signal for PLC or DCS input cards. The full-scale range reaches 0–10 mils pp (0–250 μm pp), while the Prox Out channel provides a 0.25–1.65 mm linear measurement span for waveform checking. Powered by +12 to +35 Vdc and allowing 1,000 Ω loop resistance, 990-10-XX-01-00 MOD 283278-01 Vibration Transmitter supports long wiring runs inside equipment skids. The transmitter operates from −35°C to +85°C and mounts on a 35 mm DIN rail near compressors, pumps, and motors. A 10 kΩ diagnostic output and 23 mA current limiting help technicians verify probe gap and vibration level. In rotating equipment control cabinets, 990-10-XX-01-00 MOD 283278-01 Vibration Transmitter continuously sends vibration amplitude to alarm logic and shutdown systems.

Applications

Measure compressor shaft vibration in PLC cabinet
Installed with a 3300 NSv probe, 990-10-XX-01-00 MOD 283278-01 Vibration Transmitter converts a 0–10 mils pp (0–250 μm) shaft movement into a 4–20 mA signal. The 7.0 m system length allows the probe to reach the bearing housing while the transmitter remains inside the control panel. PLC analog input modules read the current loop directly for alarm and trip logic.

Monitor pump bearing movement during operation
Using the 0.25–1.65 mm linear measurement range, 990-10-XX-01-00 MOD 283278-01 Vibration Transmitter tracks shaft displacement on small process pumps. The 23 mA current limiting protects the loop when excessive vibration occurs, enabling maintenance staff to detect bearing wear early.

Send motor vibration signal to DCS monitoring screen
Powered by +12 to +35 Vdc, 990-10-XX-01-00 MOD 283278-01 Vibration Transmitter outputs proportional vibration amplitude to DCS I/O cards. The 1,000 Ω loop resistance supports long cable routing across equipment skids without adding external signal conditioners.

Verify probe gap during commissioning
The 10 kΩ Prox Out diagnostic port of 990-10-XX-01-00 MOD 283278-01 Vibration Transmitter provides waveform and gap voltage through a BNC connector with up to 3 m leadwire distance. Technicians connect a portable analyzer to set probe target spacing and confirm proper installation.

Trigger shutdown logic on turbine skids
When vibration approaches the 10 mils pp full-scale range, 990-10-XX-01-00 MOD 283278-01 Vibration Transmitter sends a high loop current close to 20 mA, allowing the control system to activate relay shutdown and protect rotating equipment.

Specifications

Competitive Advantage

Connect directly to analog input cards
Because 990-10-XX-01-00 MOD 283278-01 Vibration Transmitter outputs a standard 4–20 mA signal, no external signal converter is required. The control system receives vibration data without additional interface modules.

Install near machinery using DIN rail
The 35 mm DIN rail mounting of 990-10-XX-01-00 MOD 283278-01 Vibration Transmitter lets installers place the transmitter inside motor control panels, reducing probe cable exposure and minimizing routing distance.

Support long field wiring runs
With allowable 1,000 Ω loop resistance at 35 Vdc, 990-10-XX-01-00 MOD 283278-01 Vibration Transmitter maintains accurate current transmission over extended cables across plant equipment areas.

Operate in wide ambient temperature range
Rated −35°C to +85°C, 990-10-XX-01-00 MOD 283278-01 Vibration Transmitter works in outdoor compressor packages, cooling towers, and enclosed skids where cabinet temperature changes significantly.

Provide on-site diagnostic signal
The built-in Prox Out waveform output of 990-10-XX-01-00 MOD 283278-01 Vibration Transmitter enables portable analyzers to read shaft motion directly, helping technicians confirm probe alignment and vibration condition without removing wiring.
