FAQ
Q1: What type / vibration sensors are compatible with the 990-05-70-03-CN?
A1: It is compatible with accelerometers and proximity probes designed for industrial vibration measurement.
Q2: How is the 4–20 mA output signal scaled?
A2: The output is typically factory-configured to represent vibration amplitude (e.g., velocity in mm/s RMS or displacement in µm peak).
Q3: Can this transmitter be used in hazardous areas?
A3: Yes, depending on the certification (ATEX, CSA, or equivalent), it can be applied in classified hazardous zones.
Q4: What is the frequency response range / this model?
A4: The device typically supports a frequency range / 10 Hz to 1 kHz, suitable for most rotating equipment monitoring.
Q5: Does it require external signal conditioning?
A5: No, the transmitter internally processes the vibration signal and directly provides a proportional 4–20 mA output.
Q6: How should the transmitter be mounted for best performance?
A6: It can be DIN rail mounted or panel mounted, with proper grounding to minimize noise interference.
Q7: What power supply voltage is recommended?
A7: A stable 24 VDC supply is recommended for optimal performance.
Q8: Can the transmitter be connected directly to a DCS?
A8: Yes, the 4–20 mA analog signal can be directly integrated into most DCS and PLC systems.
Q9: How does it handle high vibration shock events?
A9: The transmitter is designed with overload protection to withstand short-term vibration shocks without performance degradation.
Q10: Is this transmitter configurable in the field?
A10: Configuration is limited; most scaling and setup are factory-defined for stability and simplicity.
