光学速度和长度传感器，旨在对移动表面和物体的速度和长度进行无接触测量，例如，线缆、带材、管材、纤维、薄膜、纸张、热钢和车辆。
该系列包括两个型号：基于物体图像的光栅空间滤波的ISD-3和基于激光多普勒干涉的ISD-5。
ISD-3系列光学速度和长度传感器规格：
- 速度范围，km/h：0.2..250
- 速度测量精度，% RMS：小于±0.15
- 距离测量精度，% RMS：小于±0.1
- 物体图像的光栅空间滤波
- 可靠地测量任何表面
- 适用于汽车和铁路应用
ISD-5系列光学速度和长度传感器规格：
- 速度范围，m/s：0.005..20
- 速度测量精度，% RMS：0.02
- 距离测量精度，% RMS：小于±0.05
- 激光多普勒干涉
- 适用于冶金、电缆生产、纺织面料等工业应用
在对物体进行校准后，消除安装轴的误差。 ** 对于典型的道路表面。在均匀且无对比度的表面上，实际的上限可能会更低。 *** 仅受照明灯的限制，因为它直接由电源供电。处理器单元和传感器电子设备具有独立的+5V线性调节器，容忍度高达35V。 由于我们持续改进传感器的努力，RIFTEK保留在事先通知的情况下更改规格的权利。
