转眼间秋天就要到来了，今天我给大家简单的介绍一下产品的基本信息，希望通过介绍大家对这个产品可以了解的更多！什么叫做Posi-flate线性振荡器，相信大家一定不是很了解，没有关系，我给大家介绍一下，它主要使用在哪个行业，怎么样使用寿命才会长一点！另外我们要在哪里才可以买到原装！
Posi-flate振荡器是用来产生重复电子讯号（通常是正弦波或方波）的电子元件。其构成的电路叫振荡电路。能将直流电转换为具有一定频率交流电信号输出的电子电路或装置。种类很多，按振荡激励方式可分为自激振荡器、他激振荡器；按电路结构可分为阻容振荡器、电感电容振荡器、晶体振荡器、音叉振荡器等；按输出波形可分为正弦波、方波、锯齿波等振荡器。广泛用于电子工业、医疗、科学研究等方面。
Posi-flate低频振荡器（low-frequency oscillator，或称LFO）是指产生频率在0.1赫兹到10赫兹之间交流讯号的振荡器。这个词通常用在音讯合成中，用来区别其他的音讯振荡器。
振荡器主要可以分成两种：谐波振荡器（harmonic oscillator）与弛张振荡器（relaxation oscillator）。
主要适用于各大中院校、医疗、石油化工、卫生防疫、环境监测等科研部门作生物、生化、细胞、菌种等各种液态、固态化合物的振荡培养。
自激多谐振荡器也叫无稳态电路.两管的集电极各有一个电容分别接到另一管子的基极，起到交流耦合作用,形成正反馈电路，当接通电源的瞬间,某个管子先通，另一只管子截止,这时，导通管子的集电集有输出,集电极的电容将脉冲信号耦合到另一只管子的基极使另一只管子导通.这时原来导通的管子截止.这样两只管子轮流导通和截止，就产生了震荡电流。
由于器件不可能参数*一致,因此在上电的瞬间两个三极管的状态就发生了变化，这个变化由于正反馈的作用越来越强烈,导致到达一个暂稳态.暂稳态期间另一个三极管经电容逐步充电后导通或者截止，状态发生翻转,到达另一个暂稳态.这样周而复始形成振荡。

VMAX? Linear Vibrator
480 Series
 

The VMAX Linear Vibrator operates with low noise levels and high force outputs and accommodates the most demanding of applications. Special end mounts, dual ports and a totally enclosed housing make it one of the most unique linear vibrators on the market. With a state-of-the-art piston design, the VMAX linear vibrator does not require a spring to start and is centrifugally balanced, which prolongs the life and increases the force output over conventional models. The VMAX vibrator comes in a variety of sizes to suit almost every application, big and small.

Suitable for Many Different Applications

The VMAX vibrator is suitable for many different applications, including vibratory conveying, vibratory compacting and discharging of either dry or wet difficult to handle bulk solids from bins and hoppers. The VMAX linear vibrator is versatile with regard to most applications because its force output can be adjusted for a wide range of requirements by simply increasing the compressed air pressure and/or volume using conventional low cost air or electrical controls. The flexibility and range of the VMAX linear vibrator can be enhanced considerably by utilizing a two mass design, where the output force can be multiplied numerous times its normal maximum output. The VMAX linear vibrator can also be used to compact materials when filling containers to achieve maximum space utilization and save shipping costs.

Cost Performance Advantages

When designed into a vibratory conveyor for instance, the VMAX linear vibrator has tremendous cost and performance advantages over using an electric vibrating motor for the drive mechanism. This is because the VMAX linear vibrator starts and stops quickly and smoothly and is more controlled for significantly better performance. It does not go through a violent resonance phase like an electric vibrating motor. When an electric vibrating motor starts and/or stops, it goes through what is called a resonance phase, where the frequency of the vibrating system is at the natural frequency of the suspension. When this happens, amplification of movement occurs and the conveyor reacts violently. In addition, this violent movement takes some time to settle down and fully stop, which is not only detrimental for many applications, but can be costly to resolve as well.

Also, because the VMAX linear vibrator operates with compressed air, it is a natural for explosion proof applications and much safer to use. When used with filtered and lubricated compressed air, the VMAX linear vibrator requires only minimal maintenance.

 Features and Benefits
