Description
The Kongsberg TRX32_FILTER (Part Number 303067B) is a specialized signal conditioning and filtering PCB module used within Kongsberg Maritime’s sensor interface and telemetry systems. Its primary function is to clean up low-level analog signals received from field sensors—such as strain gauges, pressure transducers, or speed pickups—by suppressing high-frequency electromagnetic interference (EMI) and noise before the signal is digitized or processed by the central control system. This module is essential for maintaining signal integrity in electrically “noisy” environments, such as engine rooms or areas with large variable-frequency drives (VFDs).

Important Technical Note: The 303067B is a passive/active filter stage. If your automation system reports “Erratic Signal” or “Signal Noise” from a specific sensor, this module may be failing to filter the input correctly. When inspecting this card, check for signs of overheated components or capacitor leakage, as these are common failure modes in older filtering boards subjected to continuous vibration. Always ensure the shielding of the sensor cable is properly terminated to the chassis ground, as the filter relies on a clean reference ground to perform its job effectively.
