Quick Detail

Description

The 990-10-70-01-00 Vibration Transmitter is a high-precision, loop-powered device designed for industrial automation, providing a reliable 4 to 20 mA proportional vibration signal for machinery control systems. This transmitter accepts input from a 3300 NSv Proximity Probe and its extension cable (system lengths of 5 m or 7 m), converting dynamic vibration and gap measurements into engineering units for predictive maintenance and automated machinery protection. The linear range of 0.25 to 1.65 mm (10 to 65 mils) and full-scale option 0-10 mils pp (0-250 μm pp) ensure precise monitoring of small shaft movements in centrifugal air compressors, pumps, motors, and fans. The 990-10-70-01-00 supports DIN-rail or bulkhead mounting, features non-isolated PROX OUT and COM terminals, and provides a BNC leadwire output for dynamic diagnostics up to 3 m (10 ft). Operating from −35°C to +85°C and with storage up to −52°C to +100°C, the 990-10-70-01-00 transmitter ensures stable performance in harsh industrial environments. Its potted construction and integrated Proximitor Sensor minimize false alarms, prevent high-output faults, and simplify installation in confined spaces, making the 990-10-70-01-00 an essential component for automated machinery monitoring systems.

Applications

Centrifugal Air Compressors
The 990-10-70-01-00 receives input from the 3300 NSv Proximity Probe to measure vibration amplitudes within a linear range of 0.25 to 1.65 mm (10 to 65 mils). The transmitter converts this into a 4–20 mA proportional signal, allowing real-time machine protection and automated speed monitoring.

Small Pumps, Motors, and Fans
Using system lengths of 5 to 7 meters, the 990-10-70-01-00 transmits accurate vibration signals to control systems for predictive maintenance. Its operating temperature range of −35°C to +85°C ensures reliable performance in various industrial environments.

Diagnostic and Automation Integration
The transmitter supports non-isolated PROX OUT and COM terminals and includes a BNC connector for dynamic vibration and gap voltage output, enabling integration with automated diagnostic systems and real-time fault detection.

Specifications

Competitive Advantage

Stable and Precise Output
With a maximum loop resistance of 1,000 Ω at 35 Vdc and current limiting at 23 mA typical, the 990-10-70-01-00 provides consistent 4–20 mA output signals, minimizing error in automated control systems.

Robust Environmental Tolerance
The potted construction and wide temperature range (operating: −35°C to +85°C; storage: −52°C to +100°C) make the 990-10-70-01-00 highly resistant to humidity, condensation, and harsh industrial conditions.

Flexible Mounting Options
With DIN rail clips or bulkhead mounting screws, the 990-10-70-01-00 supports automated system designs requiring quick installation, modularity, and maintenance efficiency.

Enhanced Safety and Fault Prevention
The Not OK/Signal Defeat circuit in the 990-10-70-01-00 prevents false alarms and high-output faults due to loose probe connections, enhancing safety and reliability in automated machinery control.
