FAQ
Q1: What type of sensors can be connected to the 990 Vibration Transmitter?
A1: The unit is compatible with seismic transducers and velocity sensors designed for vibration monitoring.
Q2: Does the transmitter provide linear scaling of vibration levels?
A2: Yes, the 4-20 mA output is linearly proportional to the measured vibration velocity or displacement.
Q3: Can the 990 transmitter filter out low-frequency noise?
A3: Yes, it incorporates internal filtering to minimize the influence of non-relevant low-frequency signals.
Q4: How does the transmitter handle signal overload or excessive vibration levels?
A4: The output saturates at the maximum 20 mA level, indicating that the vibration exceeds the configured range.
Q5: Is it possible to adjust the measurement range?
A5: Yes, depending on the specific configuration, the transmitter can be ordered with different full-scale ranges.
Q6: What is the typical frequency response of the 990 transmitter?
A6: The standard response covers approximately 10 Hz to 1 kHz, suitable for most machinery applications.
Q7: Does the transmitter require external signal conditioning?
A7: No, it is a standalone loop-powered device that conditions and outputs the vibration signal directly.
Q8: How is calibration performed?
A8: Calibration is done using standard vibration test equipment and adjusting against known reference signals.
Q9: Can the transmitter be used in hazardous areas?
A9: It can be supplied in versions certified for hazardous environments, depending on the installation requirements.
Q10: What diagnostic features does the transmitter provide?
A10: It includes fault indication through signal output abnormalities, helping detect wiring or sensor issues.
