Import Bently Nevada 3500/93 Tachometer Module — Buy in wholesale FOB from Supplier in China

The Bently Nevada 3500/93 Tachometer Module is a speed monitoring instrument designed for the 3500 series machinery protection system, processing shaft rotational speed signals from proximity probes and magnetic pickup sensors. This module measures and conditions pulse inputs to provide accurate RPM data for overspeed protection, trend analysis, and machine control in critical rotating equipment. The unit accepts inputs from both eddy current proximity probes and passive magnetic pickups, with programmable speed range and alarm setpoints configurable through the 3500 rack software. Xiamen Zhexun Electric Automation Co., Ltd. supplies this module as an OEM-compatible replacement component for industrial maintenance and upgrade programmes.

Construction utilises FR4 PCB laminate with copper circuitry and an ABS housing designed for DIN rail or rack mounting within the 3500 system chassis. The module operates on 24V DC supply derived from the rack backplane, with standard industrial operating temperature range. Signal processing includes peak detection, waveform analysis, and digital filtering to ensure stable speed measurement despite shaft runout or electrical noise. The 3500/93 interfaces with the 3500 system display and communication modules to provide real-time speed indication and alarm status to plant operators and automated control systems. In typical applications, the module supports speed ranges from near-zero to tens of thousands of RPM depending on sensor type and pulse count per revolution.

Primary buyers include power generation facilities maintaining gas and steam turbines, oil and gas operators with centrifugal compressors, and heavy industrial plants with large motors and generators. The 3500/93 enables compliance with ISO 10817 vibration monitoring standards by providing the speed reference necessary for vibration spectrum analysis. Importers should confirm with Xiamen Zhexun Electric Automation Co., Ltd. the exact sensor compatibility, whether the module firmware supports their specific application requirements, and any calibration or configuration services provided. The module's role in machine protection makes verification of functional condition prior to installation particularly important.
