Zhuang Diao PLC
The 990-04-50-03-00 990 Vibration Transmitter is specifically designed for original equipment manufacturers (OEMs) of centrifugal air compressors, small pumps, motors, and fans. It provides a simple 4 to 20 mA proportional vibration signal,allowing seamless integration with machinery control systems for monitoring and protection.
This two-wire, loop-powered device works with the 3300 NSv proximity probe and its matching extension cable, available in 5 m and 7 m system lengths. The transmitter processes the signal into peak-to-peak vibration amplitudeengineering units and outputs a proportional 4 to 20 mA signal, which serves as input for the control system, enabling machinery protection alarms and logic functions.
Key Features
Integrated Proximitor Sensor – No need for an external unit.
Dynamic Signal Output – Provides a non-isolated "PROX OUT" and "COM" terminal along with a coaxial connector, enabling dynamic vibration and gap voltage signal output for diagnostics.
Adjustable Loop Settings – Features non-interacting zero and span potentiometers (under the transmitter label) for easy loop adjustments.
Test Input Function – Allows quick verification of the loop signal output using a function generator.
Signal Defeat Circuit – Prevents false alarms or high outputs caused by a faulty proximity probe or loose connections.
Flexible Mounting Options – Supports both DIN-rail clips and bulkhead mounting screws for easy installation.
This vibration transmitter ensures reliable and accurate vibration monitoring, making it an ideal choice for industrial applications requiring efficient machinery protection and diagnostics.
