BENTLY NEVADA 990-05-70-01-05 Vibration Transmitter Outstand the 990 Vibration Transmitter System

What is the 990 Vibration Transmitter System?

The 990 Vibration Transmitter is intended primarily for the original equipment manufacturers (OEMs) of centrifugal air compressors or small pumps, motors, or fans who prefer to provide a simple 4 to 20 mA proportional vibration signal as the input to their machinery control system.

990-05-70-01-05 is TSI spare parts. The transmitter is a two-wire, loop-powered device that accepts input from our 3300 NSv proximity probe and its matching extension cable (available in 5 m and 7 m system length options).
The transmitter conditions the signal into appropriate peak to-peak vibration amplitude engineering units, and provides this value as a proportional 4 to 20 mA industry-standard signal as the input to the control system where machinery protection alarming and logic occurs.

What is the Accessories of 990-05-70-01-05?

122115-01:990/991 Test Adapter. Package includes: 990/991 Test Adapter, 9V battery, Universal AC Adapter, Power Cord (North American), User Guide and Soft Carrying Case.
The 990/991 Test Adapter inverts and isolates the PROX OUT signal from the 990 Transmitter so that you can connect 990 Transmitters to AC-powered diagnostic equipment. The Adapter modifies the PROX OUT signal so that it matches our standard Proximitor sensor signals
123266-01:Coaxial Cable Kit. Includes 4 cables with length of 1.5 meters (5 feet) each.
02211505: Single coaxial cable with length of 1.5 meters (5 feet)
330153-05:Cable Connector Kit. Package Includes 1 set of 75 Ω miniature male and female connectors, shrink tubing and 3300 Isolator Seal for protection of coaxial connectors.

Why is this system stand out?

Integrated Proximitor Sensor requires no external unit
Non-isolated PROX OUT and COM terminals plus a coaxial connector to provide a dynamic vibration and gap voltage signal output for diagnostics.2
Non-interacting zero and span potentiometers under the Transmitter label supports loop adjustment.
Test Input pin for quick verification of loop signal output, using a function generator as the input.
A Not OK/Signal Defeat circuit prevents high outputs or false alarms due to a faulty proximity probe or loose connection.
Choice of DIN-rail clips or bulkhead mounting screws as standard options simplifies mounting.
