Product Info

The Model-9403 is an amplifier designed to support both simplified monitoring via DC output (+2VDC) and waveform analysis via AC output (±2V) using vibration sensor signals. It offers three selectable measurement modes—acceleration, velocity, and displacement—which can be switched using internal jumpers. Output levels can also be adjusted (LOW / MID / HIGH) to match application needs.

The DC output can be connected to PLCs for continuous monitoring, while the AC output is ideal for detailed analysis with FFT analyzers. Additionally, it features a through-out function, allowing a single sensor signal to be shared across multiple devices.

SHOWA SOKKI offers product sales and support throughout Thailand, including industrial zones in Chonburi, Rayong, Ayutthaya, Pathum Thani, and Bangkok. Feel free to contact us for more information.
