• 2022-01-23

An outdoor marine tachometer, including an infrared transmitter, which is fixed on the rotating shaft of the engine for transmitting infrared signals; An infrared receiver for receiving an infrared signal; A counting unit for detecting the number of times of the received infrared signal; The CPU is provided with a time unit, a processing unit and a comparison unit. The processing unit is used to process the acquired time and the number of times of receiving infrared signals to obtain the speed value and the speed data signal respectively. The comparison unit is provided with two predetermined times in unit time to compare with the speed value. When the speed value falls outside the interval of the two predetermined times, The comparison unit outputs an alarm signal; A display unit for receiving a speed data signal and displaying speed data; The alarm is used to receive the alarm signal output by the comparison unit and send out audible and visual alarm The invention can timely remind the driver of possible engine failure to improve vigilance.

Marine tachometer is mainly used to measure the speed of diesel engine. It is also suitable for measuring the speed of locomotive and other types of engines. Marine tachometer is used to indicate the speed of diesel engine, which is stable and accurate. It is composed of sensor, converter and tachometer.

Marine Tachometer to monitor the rpm of your engine from teleflex and faria.The tachometer of Hemu International TradeCo.,Ltd. is designed to measure accurate machine speed to achieve effective machine performance. The utility model relates to an outdoor marine tachometer, which comprises an infrared transmitter, which is fixed on the rotating shaft of an engine for transmitting infrared signals; An infrared receiver for receiving infrared signals.

The instrument adopts connector connector, which is convenient for installation. 4C or 5C harness can be used for external electrical connection. Wiring mode of instrument in use: compatible with VDO curve and Faria. It can be directly replaced as long as the parameters of instrument and sensor match. The external electrical connection is a 4C or 5C harness. It is suitable for various speed sensors to accurately display the traveling speed of vehicles and ships.

The instrument adopts cross coil to drive the pointer, which has good durability and earthquake resistance; Operating temperature: - 40 ℃ ~ + 85 ℃; Protection grade: IP67, with strong waterproof and anti fog functions and strong compatibility. It is applicable to all kinds of vehicles, ships, yachts and generator sets, and will not be affected for outdoor use.
