1、 Overview

The complete set of zz3 electric tachometer is used to measure the speed and steering of the ship's propulsion stern shaft. It can be used in the environment with impact, vibration, salt fog, oil fog, condensation, mold, air relative humidity less than 98% and temperature from - 25% to + 55 ℃. The indicator on the port side is marked with "backward" on the left side of the dial and "forward" on the right side, while the indicator on the starboard side is marked with the opposite sign.

Supply scope of complete set:

1. One zcfy-12th hydro magnetic tachogenerator.

2. Zz3 indicator (each tachogenerator can drive 16 indicators at the same time), and the range should be provided when ordering.

3. One detachable sprocket and one integral sprocket, and the shaft diameter shall be provided when ordering.

4. Roller chain, length should be provided when ordering.
