McNab Shaft Torque Data Transmitter Simulator

Marine Systems > Shaft Horsepower / Torque Meters > Shaft Torque Data Transmitter Simulator

General Description

The McNab “Data Transmitter Simulator” (Catalogue#: 500298) is a complete solid-state battery powered simulator that provides FM telemetry circuitry to simulate shaft torque. It is suitable for all McNab (LVDT or Strain Gage Sensors) shaft torque monitoring systems. It is particularly useful for shipboard personnel to functionally verify the torque meters for pre-underway check out.

Application

The simulator is a tool used for functional testing and trouble-shooting. By simulating torque shaft mounted components without having to remove anything from shaft, the simulator transmits a modulated signal to the ship Signal Conditioner Receiver for processing. Various torque valves can be switched in simulate the entire range of the torque meter. An operating manual (#616) is provided with each unit.
