RPM-Meter LCD-Display Engine Tach-Hour Meter Tachometer Gauge for Car-Motorcycle
Features: This product is a multifunctional speed measuring/counting table with speed measuring function, counting function and upper limit alarm output function. It is generally applicable to all kinds of mechanical equipment such as harvesters, fan, etc, where the speed of devices needs-to be measured.
This product is compatible-for Hall switch, metal proximity switch, infrared-proximity switch and other detection switch signals.
This product can output an NPN-alarm signal, and the user can connect an indicator lamp-and a sound-generator for warning. Users can customize the alarm field-value.
The of this product is a three-wire which adopts electronic technology, so that the has high sensitivity, strong reliability, good anti-interference stable operation in the growth period, and can be used for speed measurement and counting.
This product adopts hall for speed measurement, and through the internal function of the program, one probe-can be used to detect multiple-points, thus improving-the detection accuracy. Multi-period average velocimetry is used for speed measurement, which has a wide low-speed and high-speed measurement range-and excellent measurement accuracy. The counting function is realized by the external counting function of the-timer of the single chip microcomputer, and the counting is stable and reliable.
