Speed standard generating device Standard speed generating device model:HAD-ZSFS

The standard speed generating device has three main characteristics: wide output range, high stability, and high resolution.

Speed range from1.00r/minto40000.00r/minExpanding uncertainty is better than5*10-5（k=3）The resolution has reached0.001r/min.

The standard speed generating device adopts advanced servo drive technology and high-quality servo system, ensuring a balance between precise speed and strong torque output. We also use precision gear sets and gearboxes, with dual axis output, to ensure that the high-speed shaft operates smoothly3000.000r/minto40000.00r/minStill in contact with the low-speed shaft1.0000r/minto3000.000r/minSimilarly, it has stable rotational speed and low noise.

Simultaneously adopting multi-core microprocessors, touch screens, virtual instruments, and third-generation frequency synthesis technology(DDSDigital direct synthesis technology)It ensures both excellent quality characteristics and convenience in operation, use, and maintenance.

exist1.0000~40000r/minUsed for the detection and calibration of Hall, photoelectric, magneto electric, magnetic sensitive and other speed sensors and supporting speed instruments; It can also be used for the detection, calibration, and verification of handheld contact tachometers.
