Basic Features

The 3500/50-01-00 Dual Channel Tachometer Module is designed to receive input from proximity probes or magnetic pickups to determine shaft rotational speed, rotor acceleration, and rotor direction.

Module size: Approximately 2.2 cm × 12.4 cm × 12.6 cm

Weight: Approximately 0.1 kg

Country of origin: United States

Functional Features

The module is programmable through the 3500 Framework Configuration Software, offering multiple configuration options to meet diverse monitoring needs, including:

Speed monitoring, setpoint alarm, and speed band alarm

Speed monitoring, setpoint alarm, and zero-speed notification

Speed monitoring, setpoint alarm, and rotor acceleration alarm

Speed monitoring, setpoint alarm, and reverse rotation notification

Additionally, the 3500/50-01-00 can be configured to provide conditioned keyphasor signals to the 3500 rack backplane, eliminating the need for a separate keyphasor module in the system.

Accuracy

The measurement accuracy of the 3500/50M Tachometer Module is ±20 rpm/min, ensuring reliable and precise speed monitoring performance.

Application Field

The module is primarily used for rotating machinery speed monitoring in industrial environments, including:

Compressors

Fans

Oxygen concentrators

Pumps

Motors

Steam turbines

It is widely applied in industries such as power generation, petrochemical, pulp and paper, and steel manufacturing, and fully complies with the API 670 standard requirements for machinery protection systems.
