Features LED DISPLAY: The digital tachometer features a 4-digit LED display for an easy and smart way to display speed, improving the user experience. WIDE MEASURING RANGE: The digital motor tachometer offers a wide speed measurement ranging from 1 to 50,000 RPM, catering to various speed measurement needs. HIGH ACCURACY: The LED tachometer maintains high accuracy through its algorithmic range measurement, instantly reflecting the rotational speed to obtain reliable measurements. STABLE PERFORMANCE: RPM speed meter adopts low-speed measurement cycle for high-speed rotation and ensures flicker-free display, which ensures stable performance. VERSATILE APPLICATION: The motor speed meter provides compact and excellent functionality that makes it suitable for a variety of speed measuring devices. Specification: Item Type: Digital Tachometer Material: ABS Speed range: 1-50000 RPM Input power supply: DC9-30V Output current: 20mA (for sensor) Error range: ±0.5‰-±1.5‰ RPM Display: 4-digit LED Size: approx. 78x42x24mm/3.07x1.65x0.94in (Standard Panel Size) Mounting hole size: approx. 76.5x39.5mm/3.01x1.56in Speed (RPM) Screen Description >50000 FULL Screen Overflow 50000~10000 X.

Low Speed Alarm Value LSP (factory: 60) When the measured speed is less than the low speed alarm value, the output port emits a signal, set to 0 to close. FPA Gear Molecules (Factory: 1) Measured Speed x Gear Numberer/Gear Denominator FPB Gear Denominator (factory: 1) CS Unevenly split gear teeth (factory: 0) When gear spacing is uneven, this can be used to set the number of sampled pulses during a revolution to measure speed. Enter the number of induced pulses for a revolution in this element. When CS 0, the electronic gear is activated. When CS is not 0, the CS parameter takes effect. LS Minimum speed measured (factory: 60) This parameter is mainly used to accelerate the tachometer zeroing time. For example, if the minimum speed is 10 RPM, it will reset to 0 in 6 Package List 1 x Digital Tachometer 1 x Sensor 2 x Magnets
