Product Details

➪The 990-05-70-03-01 is a Bently Nevada 990 Series Vibration Transmitter designed primarily for original equipment manufacturers (OEMs) of centrifugal air compressors or small pumps, motors, and fans who prefer to provide a simple 4 to 20 mA proportional vibration signal as the input to their machinery control system .

➪The transmitter is a two-wire, loop-powered device that accepts input from a Bently Nevada 3300 NSv proximity probe and its matching extension cable .

➪Full-scale: 05-0-5 mils pp (0-125 μm pp)

System Length: 70-7.0 meters (23.0 feet)

Mounting: 03-DIN clips and screws

Agency Approval: 01-CSA Division 2

➪Power Requirement: +12 to +35 Vdc input at the transmitter terminal

➪Current Limiting: 23 mA typical

➪Operating Temperature (Transmitter): -35°C to +85°C (-31°F to +185°F)

➪Storage Temperature (Transmitter): -51°C to +100°C (-60°F to +212°F)

➪Probe Operating Temperature: -35°C to +177°C (-31°F to +350°F)

Features

·Integrated Proximitor Sensor : The integrated Proximitor sensor requires no external unit, simplifying installation and reducing cabinet space requirements .

·Two-Wire Loop-Powered Design : The transmitter operates as a two-wire, loop-powered device, requiring only +12 to +35 Vdc input and providing simple integration into existing control systems .

·Diagnostic Outputs : Non-isolated PROX OUT and COM terminals plus a coaxial connector provide a dynamic vibration and gap voltage signal output for diagnostics, allowing machinery health assessment without additional sensors .

·NOT OK/Signal Defeat Circuit : Prevents high outputs or false alarms due to faulty proximity probes or loose connections by driving the output below 3.6 mA within 100 μs of a fault condition .

·Power-up Inhibit Circuit : Eliminates signal errors due to line voltage transients by keeping the output below 3.6 mA for 2-3 seconds after power application .
