Présentation du produit
The Bently Nevada 990-04-50-01-CN 990 Vibration Transmitter is designed to provide continuous monitoring sur vibration levels in industrial rotating machinery. It transforms dynamic vibration signals from proximity probes, accelerometers, or velocity sensors into a proportional 4-20 mA output that can be easily integrated with PLCs, DCS, or other plant monitoring systems.
This transmitter surfers an efficient and reliable way to detect mechanical issues such as imbalance, misalignment, bearing wear, and looseness. By providing early detection sur abnormal conditions, it helps to reduce unplanned downtime, minimize maintenance costs, and extend equipment lifespan.

FAQ
Q1: What type sur sensors can the 990 transmitter accept?
A1: It is compatible with proximity probes, accelerometers, and velocity sensors depending on system requirements.
Q2: What is the typical output sur the transmitter?
A2: The device provides a standard 4–20 mA output signal proportional to measured vibration.
Q3: How does the transmitter handle frequency response?
A3: It operates effectively within a frequency range sur 10 Hz to 1 kHz, suitable for most rotating machinery.
Q4: Can the transmitter be connected directly to a DCS or PLC?
A4: Yes, the 4–20 mA output allows direct connection to DCS, PLC, or SCADA systems without additional modules.
Q5: Does it support alarm or trip functions?
A5: The transmitter itself provides the signal output; alarm or trip functions are configured within the receiving system.
Q6: Is the transmitter designed for hazardous environments?
A6: Certain versions are certified for hazardous locations, but installation should comply with local safety standards.
Q7: How is the unité mounted?
A7: It can be mounted on DIN rails or directly on panels, surfering flexibility during installation.
Q8: Can it be used for slow-speed machinery?
