Quick Detail

Description

The 990-04-50-01-CN Vibration Transmitter is a high-precision, loop-powered vibration transmitter designed for industrial automation and machinery protection systems. The 990-04-50-01-CN Vibration Transmitter accepts input from a single 3300 NSv Proximity Probe and its extension cable, converting vibration signals into a proportional 4 to 20 mA output for process control systems. With a linear range of 0.25 to 1.65 mm (10 to 65 mils) and full-scale vibration measurement of 0-4 mils pp (0-100 μm pp), the 990-04-50-01-CN Vibration Transmitter provides accurate, real-time peak-to-peak vibration data for centrifugal air compressors, small pumps, motors, and fans. The device operates over an extended temperature range from -35°C to +85°C (-31°F to +185°F), with storage from -52°C to +100°C (-62°F to +212°F). Its 10 kΩ output impedance, maximum loop resistance of 1,000 Ω at 35 Vdc, and typical current limit of 23 mA ensure reliable and consistent signal delivery. The 990-04-50-01-CN Vibration Transmitter features integrated Proximitor Sensor capability, non-isolated PROX OUT and COM terminals, and a coaxial connector for dynamic vibration and gap voltage diagnostics. Standard mounting options include 35 mm DIN rail clips or bulkhead screws, while potted construction allows operation in 100% condensing humidity environments. Compatible with 5-meter system lengths and 3-meter Proximitor sensor leadwire, the 990-04-50-01-CN Vibration Transmitter provides precise vibration monitoring in automated industrial machinery.

Applications

Centrifugal Air Compressor Vibration Monitoring
The 990-04-50-01-CN Vibration Transmitter is ideal for centrifugal air compressors where compact installation and accurate vibration feedback are required. Its full-scale option of 0-4 mils pp and linear range of 0.25 to 1.65 mm allow precise measurement of radial and axial vibrations. The transmitter’s compatibility with a 3300 NSv Proximity Probe ensures reliable input in confined spaces, while the 35 mm DIN rail mounting facilitates integration into automated compressor monitoring systems.

Small Pumps, Motors, and Fans Condition Monitoring
For small pumps, motors, and fans, the 990-04-50-01-CN Vibration Transmitter provides real-time vibration signals to machinery control systems. Its output impedance of 10 kΩ and maximum loop resistance of 1,000 Ω guarantee signal stability over distances up to 3 meters from the Proximitor sensor, enabling predictive maintenance and alarm triggering in automated equipment.

Process Automation and Control Integration
The 990-04-50-01-CN Vibration Transmitter supports seamless integration into industrial automation systems. Loop-powered operation between +12 to +35 Vdc allows direct connection to control loops, while the transmitter’s integrated Proximitor Sensor and dynamic PROX OUT signals enable automated diagnostics, including peak-to-peak amplitude monitoring and gap voltage analysis.
