Quick Detail

The 990-04-XX-01-01 MOD:165335-01 Vibration Transmitter is engineered for industrial automation environments that require a simplified yet reliable vibration monitoring interface for centrifugal compressors, pumps, motors, and small rotating machines. Designed as a two-wire loop-powered device, the transmitter accepts input from a 3300 NSv proximity probe and extension cable and converts dynamic vibration amplitudes into a proportional 4–20 mA signal for direct integration into plant control systems and OEM machinery controllers. This enables continuous condition monitoring and alarm logic without the need for separate proximitor hardware. Featuring DIN-rail mounting options, CSA Div 2 approvals, and operating temperature capability from −35°C to +85°C, the 990-04-XX-01-01 MOD:165335-01 Vibration Transmitter supports stable operation in confined machinery spaces and high-humidity industrial locations. With a full-scale range of 0–4 mils peak-to-peak and a linear range of 0.25 to 1.65 mm for Prox Out, the transmitter enables predictive maintenance strategies and diagnostics within automated vibration monitoring networks. The integrated Proximitor circuitry, test pin input, zero/span adjustments, and fault/Not-OK protections further enhance operational reliability for OEM process equipment and industrial control applications.

Applications

Application 1 Centrifugal Air Compressors
Ideal for OEM compressor packages where limited space and small clearances require the use of NSv probes and 4–20 mA vibration feedback for protection loops.

Application 2 Industrial Pump Skids
Full-scale 0–4 mils pp measurement supports monitoring of hydraulic pump vibration amplitudes for bearing health assessment in petrochemical and refining environments.

Application 3 Small Motors and Fans
Two-wire loop power and DIN-rail mounting reduce installation complexity for motor skids and fan units, enabling continuous vibration tracking in HVAC and process utilities.

Application 4 Compact Machinery Control Panels
4–20 mA output integrates directly into PLC, DCS, and safety interlock panels without requiring external proximitor modules, reducing footprint and wiring congestion.

Application 5 High-Humidity Industrial Areas
Potted construction supports operation in up to 100% condensing humidity, suitable for cooling towers, compressor rooms, and wet process areas.

Specifications

Competitive Advantage

Competitive Advantage 1 Integrated Proximitor Functionality
Eliminates external proximitor devices, reducing wiring, failure points, and OEM panel space consumption by approximately 20–30%.

Competitive Advantage 2 Direct 4–20 mA Industrial Signal
Industry-standard current-loop output allows instantaneous compatibility with PLC/DCS systems used in plant automation and protection control.

Competitive Advantage 3 High Environmental Stability
−35°C to +85°C operating temperature plus CSA Div 2 approval extend deployment into hazardous compressor trains and refinery utilities.

Competitive Advantage 4 Fault Handling & Not-OK Logic
Signal defeat circuitry prevents false alarming due to probe faults or loose connectors, improving system reliability in predictive maintenance networks.

Competitive Advantage 5 Adjustable Calibration & Diagnostics
Zero/span potentiometers, Prox Out diagnostics, and test input terminals support calibration verification and commissioning without removing the transmitter from service.
