製品紹介
The Bently Nevada 990-04-50-01-CN 990 Vibration Transmitter is designed to provide continuous monitoring / 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 /fers an efficient and reliable way to detect mechanical issues such as imbalance, misalignment, bearing wear, and looseness. By providing early detection / abnormal conditions, it helps to reduce unplanned downtime, minimize maintenance costs, and extend equipment lifespan.

FAQ
Q1: What type / 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 / 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 / 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 台 mounted?
A7: It can be mounted on DIN rails or directly on panels, /fering flexibility during installation.
Q8: Can it be used for slow-speed machinery?
A8: Yes, provided the vibration frequency falls within the supported 10 Hz–1 kHz range.
Q9: What power supply does the transmitter require?
A9: The 台 typically operates on a 24 VDC power supply.
Q10: How is sensor calibration managed with this transmitter?
A10: Sensor calibration is performed before connection; the transmitter scales the input signal to match the 4–20 mA output.
