Yh-tc01 DC9-24V เครื่องวัดรอบเครื่องยนต์ดิจิทัล 4 หลัก 0.56 นิ้ว

Features:
1.This product is a multi-function speed measuring/counting meter with speed measuring function counting function and upper limit alarm output function.
2.With reliable performance simple installation and wide application range it is generally applicable to all kinds of mechanical equipment such as harvesters machine tools motors fans etc. where rotational speed measurement is required for devices as well as production counting and other occasions.
3.This product is compatible with Hall switch metal proximity switch infrared proximity switch and other detection switch signals.
4.This product can output a channel of NPN alarm signal and the user can connect the indicator light and sounder for warning. The user can customize the alarm field value.
5.The supporting sensor of this product is a three-wire sensor which uses electronic technology to make the sensor have high sensitivity strong reliability good anti-interference performance stable operation in the long term and can be used for speed measurement and counting functions.
6.This product adopts Hall sensor for speed measurement. Through the internal function of the program one probe can be set for multiple detection points thus improving the detection accuracy. The speed measurement adopts the multi-period average speed measurement method which has a wide range of low speed high speed measurement and excellent measurement accuracy. The counting function is realized by the external counting function of the single-chip timer which is stable and reliable.
