FAQ
Frequently Asked Questions (FAQ)
Q1: What is the primary application of the 330425-01-05 accelerometer?
A1: It is designed for casing acceleration measurements in critical rotating machinery, such as gear mesh monitoring or bearing housing vibration monitoring.
Q2: What frequency range does the sensor support?
A2: The frequency response is 10 Hz to 15 kHz (±3 dB), suitable for high-resolution vibration detection.
Q3: Are there special installation requirements for this sensor?
A3: Yes, it should be installed directly on the bearing housing or machine casing for accurate signal transmission. Improper mounting can lead to degraded response or false readings.
Q4: Is a mounting base necessary?
A4: For units with serial numbers not beginning with “G”, it is strongly recommended to use the supplied API mounting base to reduce base strain sensitivity.
Q5: What is the maximum cable length the sensor can support?
A5: The sensor can support up to 305 meters (1000 feet) of cable without signal degradation.
Q6: What type of output signal does the 330425-01-05 provide?
A6: It outputs a voltage signal with a sensitivity of 25 mV/g, which correlates to the measured acceleration.
Q7: What hazardous area certifications does this model have?
A7: It has multiple certifications including ATEX, IECEx, and CSA/NRTL/C for intrinsically safe and non-incendive environments.
Q8: What is the operational temperature range of the sensor?
A8: The 330425-01-05 can operate in environments ranging from -55°C to +121°C, making it suitable for extreme industrial conditions.
