4. Structure and Composition

• Signal Input Terminal: Used to connect various sensors, such as eddy current sensors and vibration sensors, to receive original measurement signals.
• Signal Conditioning Module: The core part of the pre-amplifier, which amplifies, filters and conditions the input original signal to convert it into a standard signal that can be recognized by the monitoring system.
• Communication Interface Module: Provides digital or analog output interfaces, supports mainstream industrial standard communication protocols, and realizes data interaction with the upper monitoring system.
• Power Supply Module: Provides stable DC power for the internal circuit of the pre-amplifier and the connected sensors to ensure normal operation of the whole system.
• Housing and Mounting Bracket: Adopts industrial-grade protective housing, which has good dustproof and anti-collision performance, and supports DIN rail or panel mounting to meet the installation needs of different control cabinets.

6. Installation and Maintenance

Installation Requirements

• Location Selection: It should be installed in the control cabinet close to the sensor to minimize the length of the signal cable and avoid signal attenuation and interference caused by excessively long cables.
• Connection Standard: Ensure that the connection between the sensor cable and the pre-amplifier is tight and firm, and the wiring is correct according to the product manual to prevent signal distortion caused by loose connections.

Maintenance Guidelines

• Regular Inspection: Regularly check the wiring terminals for looseness, and inspect the housing for corrosion, scratches or other physical damage to ensure the integrity of the equipment.
• Calibration Suggestion: The pre-amplifier itself generally does not require regular calibration, but it is necessary to ensure that its supporting 3300 XL series sensors are calibrated regularly to ensure the accuracy of measurement data.
• Troubleshooting Steps: If the monitoring data is abnormal, first check whether the power supply voltage is stable and the communication connection is normal; if there is no problem, check the sensor signal input to eliminate sensor faults.
