频闪仪购买需要注意哪些技术细节？

频闪仪购买需要注意的问题：

频闪灯是一种可以使旋转、往复、摆动或振动的物体看起来静止不动的设备。这称为定格动画效果。如果在使用频闪仪观察时移动的物体看起来是静止的，则频闪仪会与物体的振动频率相协调。

工业频闪仪是一种测量仪器，通常用于检查运动中不同机器部件上的应力。例如，工业频闪灯可用于印刷车间，以评估打印机滚筒的转速。因此，工业频闪仪也可以用作转速计，以计算循环运动部件的转数或每分钟转数 （RPM）。

在购买电子工业频闪仪之前，必须考虑预期的应用。LED频闪仪可以达到几千赫兹的闪光频率，从而可以对非常快的序列进行光学检查。因此，频闪仪的闪光频率必须适应对要检查的转子、齿轮、凸轮、轴、主轴等的测量。

除了调整闪光频率外，频闪仪还提供设置相移的可能性。这意味着闪光脉冲以图像光学旋转的方式延迟。这样就可以将旋转部件上的标识品牌移动到正确的位置。

用于工业维护的非接触式频闪仪。购买LED频闪仪时要评估的一个关键因素是频闪仪使用的光源类型。现代发光二极管 （LED） 频闪仪与传统的氙气闪光灯没有任何共同之处。在现代 LED 频闪仪中，强大的 LED 阵列能够对物体进行全面照明。由于 LED 频闪仪的可扩展性，即使是移动的纸幅等大型部件也可以轻松检测。对于某些无损检测应用，可能需要使用紫外线 （UV） LED 的特殊频闪仪。

灯具的触发器是频闪灯的另一个重要组成部分。简单的频闪仪具有内部调节器，用于控制 LED 灯具或氙气管。在这些频闪仪灯设计中，无法从外部触发。更复杂的频闪仪配备了触发输入，允许外部速度传感器控制灯具。因此，频闪仪的闪烁始终等于物体的转数或振荡次数。当驱动辊子的不同转速时，这一点尤其有利。尤其是在纸张生产领域或印刷品测试期间，情况尤其如此。

对于手持式频闪仪，决定性因素是电源的执行方式。在这里，频闪仪的使用频率至关重要。如果偶尔使用手持式频闪仪，电池供电通常就足够了。如果经常使用手持式频闪仪灯，建议使用可充电电池供电。固定安装频闪仪通常配有交流电源适配器或直接由电源供电。

购买频闪仪时，还应考虑应用所需的入口防护 （IP） 等级。IP 等级或等级指定设备是否防尘或防水。如果在恶劣的工业条件下使用频闪灯，建议使用 IP67 等级，以***佳保护免受外部环境影响。

A stroboscope light is a piece of equipment that can make a rotating, reciprocating, oscillating or vibrating object appear still. This is referred to as a stop-motion effect. If a moving object appears to be stationary when observed with a stroboscope, then the stroboscope is attuned to the vibration frequency of the object.

An industrial stroboscope light is a measuring instrument commonly used to inspect stresses on different machine parts in motion. For example, an industrial stroboscope light can be used in a print shop to evaluate the rotational speed of a printer roller. Thus, an industrial stroboscope also can be used as a tachometer to count the number of revolutions or measure the revolutions per minute (RPM) of a cyclically moving part.

Before purchasing an electronic industrial stroboscope light, one must consider the intended application. An electronic stroboscope can reach a flash rate of several thousand Hertz, making it possible to carry out optical inspections for very fast sequences. Therefore, the stroboscope's flash rate must accommodate measurement of the rotors, gears, cams, shafts, spindles, etc. to be inspected.

In addition to the adjustment of the flash rate or flash frequency, modern stroboscopes also offer the possibility of setting a phase shift. This means that the flash pulse is delayed in such a way that the picture optically rotates. This makes it possible to move the marking brands on the rotating parts into a correct position.

Non contact stroboscope in use for industry maintenance.A key factor to evaluate when buying an electronic stroboscope light is the type of light source used by the strobe. Modern light-emitting diode (LED) stroboscopes have nothing in common with the conventional Xenon flashers. In modern LED stroboscopes, powerful LED arrays enable comprehensive illumination of an object. Due to the scalability of the LED stroboscopes, even large parts like moving paper webs can be inspected with ease. For certain non-destructive testing applications, special stroboscopes that utilize ultraviolet (UV) LEDs may be required.

The trigger of the luminaire is another important component of the stroboscope light. Simple stroboscopes have internal regulators to control the LED luminaires or xenon tubes. Triggering from outside is not possible in these stroboscope light designs. More complex stroboscopes are equipped with trigging inputs that allow external speed sensors to control the luminaires. Thus, the flashing of the stroboscope is always equal to the number of revolutions or oscillations of the object. This is particularly advantageous when different rotational speeds of rollers are driven. This is the case especially in the sphere of paper production or during the testing of printed products.

In the case of handheld stroboscopes, the decisive factor is how the power supply is performed. Here it is of crucial importance how often the stroboscope is used. If the handheld stroboscope is used sporadically, a battery power supply is often sufficient. If the handheld stroboscope light is used frequently, a rechargeable battery power supply is recommended. Fixed installation stroboscopes are generally supplied with an AC power adapter or powered directly from the mains.

When acquiring a stroboscope, one should also think about the ingress protection (IP) rating required for the application. The IP rating or class specifies whether a device is dustproof or waterproof. If a stroboscope light will be used in harsh industrial conditions, an IP67 rating is recommended for optimal protection against external environmental influences.
