Connect Capacitive Sensors in Series for Smarter Equipment Control

Use multiple capacitive sensors to verify different conditions before equipment starts. Series connection provides a simple way to improve control of feeding and material handling equipment.

When one sensor is not enough

In many automated feeding systems, equipment is controlled based on whether material is detected at a single point.

But sometimes you need to know what is happening in two places at the same time.

Is there feed available in the hopper? Is the feed pan already full? Should the auger actually be running?

By connecting capacitive sensors in series, you can use multiple detection points as one condition for controlling the equipment.

How series-connected sensors work
The SCR SE series from dol-sensors is designed for applications where two or more capacitive sensors need to be connected in series. When the sensors are connected in series, the output is activated only when all connected sensors are triggered. This makes it possible to verify conditions at multiple points before activating or deactivating equipment – without requiring a separate control signal from each sensor. Sensor 1 Detects the material or condition at the first point. + Sensor 2 Detects the material or condition at the second point. = Equipment control The output is activated when the required conditions are met.

A simple example: Controlling a feed auger

One sensor can be installed in the hopper to detect whether feed is available, while another sensor monitors the feed pan.

Connecting the two sensors in series allows the status at both locations to be taken into account when controlling the feed auger.

For example, this can prevent the auger from running when the hopper is empty.

The result is a simple way to reduce unnecessary empty running, helping to limit equipment wear and unnecessary energy consumption.

Simple series connection. No additional control system required.

The SCR SE sensors are connected directly in series with the load.

The sensors have no polarity requirements, making installation straightforward. Built-in overload and short-circuit protection also help protect the sensors in demanding applications.

For OEMs, this provides a simple way to introduce multi-point detection into feeding equipment without unnecessarily increasing system complexity.

Designed for demanding agricultural applications

dol-sensors capacitive sensors are developed for reliable detection in demanding environments found in poultry and pig production.

They can be used to detect feed and other materials without mechanical moving parts, making them well suited for automated feeding and material handling equipment.

Could series connection improve your equipment?

Every feeding system is different. The optimal sensor setup depends on what you need to detect, where the sensors are installed and how the equipment should respond.

机械开关损坏会导致牲畜饲料管线出现问题

在畜牧业生产领域,高效可靠的饲料输送系统至关重要。这些系统通常依靠传感器来调节和监控进料流量。

其中最常用的是机械开关和电容式传感器。尽管每种传感器都有其优点,但与电容式传感器相比,机械开关存在一些不同的问题。

机械开关:容易磨损

机械开关通过物理接触起作用,这本身就使它们容易磨损。在牲畜饲料生产线中,这些开关会不断移动,饲料会磨损,从而导致其组件逐渐退化。随着时间的推移,这可能导致:

增加维护

随着零件磨损,需要经常更换和调整。这意味着需要更多的工作,对牲畜造成更多不必要的干扰。

不准确

磨损的开关可能无法准确检测进料水平,从而导致过量填充或进料不足。每位农场经理都知道,这将对产量产生巨大影响,因为它会增加垃圾中霉菌形成的风险,导致饲料泄漏,并显著影响牲畜的生长。

停机时间

机械开关的故障可能会中断供电过程,从而导致运行停机。与不准确的情况一样,停机时间会影响牲畜的生长,在极端条件下会导致大量的生产损失。

饲料供应涉及将原材料、原料或混合饲料运送到工厂、植物或动物养殖企业等生产场所。保持稳定可靠的饲料供应对于任何生产场所的有效运转以及农业环境中动物的福祉至关重要。

将电容式传感器纳入馈电供应管理

通过集成电容式传感器,可以提高饲料供应链的有效性。电容式传感器是测量材料中存储的电荷容量或量的电子设备。它们通过检测电容的变化来工作,电容是材料储存电荷的能力。

电容式传感器在管理馈电电源方面具有广泛的应用。例如,它们可以有效地衡量垃圾箱、筒仓或储罐等存储设施中的原材料数量。这种监控有助于避免材料短缺,并由于足够的原材料或复合饲料可用性而保证不间断生产。

监控流量

电容式传感器还可用于监控通过管道或传送带运输的原材料的流量。这有助于优化向生产过程供应材料的速度,确保原材料既不过剩也不缺乏。

总体而言,在进料供应过程中使用电容式传感器有助于提高效率、降低成本并防止生产中断。它们为监测和控制原材料流动提供了一种可靠且具有成本效益的手段,确保生产能够保持在最佳水平。
