5 Digital LED Display Tachometer High Precision RPM Speed Meter Digital Ratemeter with Reverse Protection for Brushless Motor

Generators5 Digital LED Display Tachometer High Precision RPM Speed Meter Digital Ratemeter with Reverse Protection for Brushless MotorNewly upgraded tachometer (frequency dual) wide voltage work DC3-15V, identifiable signals are: dry contact, NPN, PNP, pulse, etc., signal amplitude 3-30V, the number of pulses (signal frequency high/low) is proportional to the speed, so the speed measurement has nothing to do with the power shape of the motor, as long as the speed pulse signal can be provided. The speed signal can be provided directly by the motor drive or by an external sensor. The meter head adopts industrial high speed MCU, strong anti-interference, stable and reliable, wide measuring range, high measuring accuracy, and the software adopts the leading full cycle measurement method, which is suitable for all the motors that can provide the pulse output of the speed signal on the market.Feature:1. This is a 5-bit high-precision digital tachometer, suitable for measuring speed/frequency dual-purpose products, frequency measurement accuracy is high, up to 0.01% at 25 degrees Celsius, resolution up to 0.001HZ.2. Can drive pulse signal, can also be connected to the external sensor, identifiable signals are: dry contact, NPN, PNP, pulse, etc.3.Wide voltage DC3-15V, can be flexibly set frequency division value, as long as the pulse signal can be provided all motor speed measurement.4. The key can switch between two working modes of frequency and speed, the working mode power off memory, the key can set the frequency division value according to different needs, the frequency division value can be set 1-99999 and 0.0001-9.9999 file frequency division value power off memory.5. Wide frequency measurement range, 0.15HZ-100KHZ.6. Automatic range switching, from 0.000HZ (R/M) to 000.00KHZ (KR/M).7. There is reverse connection protection, positive and negative lines are not burned, the measurement signal amplitude is 3-30V, more than this parameter may be damaged.Specifications:Display number: 5 digits LED digital tube display numberRefresh rate: signal frequency >3HZ:3 times/second; Signal frequency 3HZ: approximately equal to the signal frequency.Measurement accuracy: 0.1% ±1digit or 0.01% at 25°CMeasuring range: 0.15HZ-100KHZ, 9r-999.99Kr /mMeasurement method: full cycle measurement methodInput resistance: 100K/ resistancePower supply: Default DC3-15VVoltage: AC2000V 1min between the external terminal and the housingVibration resistance: Vibration number :10-55HZ, acceleration 50m/s? 5minX10 inX, Y and Z directionsNote:1.Due to the light and screen difference, the item's color may be slightly different from the pictures.2.Please allow 1mm-1cm differences due to manual measurement.Package includes:1x Tachometer
