how to wire a tachometer on a boat

• 2023-03-03

The tachometer wiring on a boat instrument panel only needs to install a tachometer sensor on the flywheel housing, and two wires are connected to the tachometer. (The two lines are different). The wiring method of marine tachometer x100r/min should add a DC motor on the main shaft of the engine (such as beside the generator). Then measure its voltage and calibrate the corresponding value with a tachometer.

Wiring method of marine tachometer x100r/min, hello, add a DC motor on the main shaft of the engine (such as beside the generator). Then measure its voltage and calibrate the corresponding value with a tachometer. The principle of speed sensor is that most of them output pulse signal (approximate sine wave or rectangular wave). The methods for measuring speed of pulse signal include frequency integration method (that is, F /V conversion method, whose direct result is voltage or current) and frequency calculation method. Most of them output pulse signals (approximate sine wave or rectangular wave). The methods for measuring speed of pulse signal include: frequency integration method (i.e., F /V conversion method, whose direct result is voltage or current), and frequency operation method (whose direct result is digital).

In automation technology, there are many measurements of rotational motion speed, and the linear motion speed is often measured indirectly through rotational speed. The DC tachogenerator can convert the rotating speed into electrical signals. The tachometer requires a linear relationship between the output voltage and the speed, and requires a large output voltage gradient and good time and temperature stability. The tachometer can generally be divided into DC type and AC type. The rotary speed sensor is in direct contact with a moving object. When the moving object contacts the rotary speed sensor, the friction force drives the roller of the sensor to rotate. The rotation pulse sensor installed on the roller sends out a series of pulses. Each pulse represents a certain distance value, so that the linear velocity can be measured.

For the preliminary installation of the speed sensor support assembly, first fix the vertical plate of the fixed support to the fixed base plate on the side of the diesel engine frame through several fastening screws, then screw the adjusting screw through the vertical slot of the vertical plate and into one end of the horizontal rod of the fixed support, and then install the adjustable support on one end of the fixed support, and the adjustable support can move flexibly.
