Quick Detail

Description

The 990-04-XX-01-00 mod 147202-01 Vibration Transmitter converts displacement signals from a 3300 NSv Proximity Probe into proportional 4–20 mA outputs for automated machinery control systems. Designed for OEMs of centrifugal compressors, small pumps, motors, or fans, the 990-04-XX-01-00 supports a 0–4 mils pp (0–100 μm pp) full-scale range with a linear measurement span of 0.25–1.65 mm (10–65 mils). The transmitter accepts a 5 m or 7 m system length probe and extension cable, operates from +12 to +35 Vdc with a 23 mA typical current, and handles loop resistances up to 1,000 Ω. Mountable via 35 mm DIN rail clips, the 990-04-XX-01-00 mod 147202-01 features integrated Proximitor Sensor output, non-isolated PROX OUT and COM terminals, and BNC connectors for live vibration and gap voltage diagnostics. Non-interacting zero/span potentiometers allow precise loop adjustment, while the Not OK/Signal Defeat circuit prevents high outputs from faulty probes. Potted construction ensures operation in 100% condensing environments, making the 990-04-XX-01-00 mod 147202-01 ideal for automated vibration monitoring in tight, high-humidity industrial installations.

Applications

Application – Radial Vibration Monitoring on Small Shafts
The 990-04-XX-01-00 mod 147202-01 can measure radial vibration on shafts smaller than 50 mm, using the 0.25–1.65 mm linear range. This allows precise detection of rotor imbalances in centrifugal compressors, motors, or pumps, ensuring accurate automated control and predictive maintenance.

Application – Axial Position Detection
Using the 3300 NSv Proximity Probe input, the 990-04-XX-01-00 mod 147202-01 measures axial displacement on flat targets up to 100 μm. The 4–20 mA output enables real-time monitoring in automated process systems.

Application – Machinery Alarm Input
The transmitter converts peak-to-peak vibration amplitude into standard 4–20 mA signals for control systems. The 990-04-XX-01-00 mod 147202-01 provides accurate input for machinery protection alarms, including tachometer and zero-speed monitoring.
