您的工厂准备好迎接智能传感器了吗?

您的工厂准备好迎接智能传感器了吗?

除非您每时每刻都在关注工厂内安装的机器的动态,否则无法始终保持最佳的生产率和效率,也无法避免计划外停机和生产损失。

传统传感器提供的信息量有限,且无法提供能与控制器交换的诊断或参数数据。集成式智能传感器解决方案提供任何必要的数据,可在任何时候全面呈现企业的状况。

作为互联企业不可或缺的组成部分,智能传感器能令您轻松访问可操作的情景化数据,有助于将整体设备效率 (OEE) 和平均故障间隔时间 (MTBF) 最大化,同时缩短机器的平均修复时间 (MTTR)

但是您如何判断您的工厂是否适合使用智能传感器?

是时候让一切明朗了:

需要频繁清洁的传感器最需要升级为智能传感器。例如,在粉尘严重和脏污的工业环境中,光电传感器镜头经常会沾上碎屑,因此需要频繁清洁以保持其性能。

此类应用可受益于智能传感器技术,它利用固有的诊断功能提醒维护人员传感器镜头脏污,但仍可检测相关物体是否存在。

以后,当碎屑积累到一定程度时,传感器将无法再检测目标。

如果使用智能传感器,维护团队在机器出现产能问题前就能得到通知,以便在常规维护周期内清洁传感器。由于能切实预防停机事件,这一特性优势显著。

某些应用中,焊渣或其他金属材料会在接近传感器表面积聚,此时也同样适合采用智能传感器。

操作人员将获悉常规维护期间需要注意机器的哪些区域,而不是等到出现产能问题或整条产线停机才行动。

要确定您是否适合选择智能传感器,其关键在于针对停机事件 (与传感器损坏和故障相关) 计算传感器配置的成本。仍不确定是否值得投资智能传感器?

It’s Time to Come Clean

Sensors that require frequent cleaning are prime candidates for a smart sensor upgrade. For example, in dusty and dirty industrial environments, photoelectric sensor lenses can often collect debris and therefore need frequent cleaning to maintain their performance.

Such applications could benefit from smart sensing technology, leveraging the inherent diagnostics to provide indication to maintenance personnel that a sensor lens may be dirty but still detecting presence/absence of objects.

In the future, the debris may build up to a point where the sensor can no longer detect the target.

When using a smart sensor, the maintenance team will be notified before the machine exhibits yield issues so the sensors can be cleaned during a normal maintenance cycle. This is extremely impactful since it actually PREVENTS downtime.

The same holds true for proximity sensors in applications involving weld slag or other metallic materials that can build up on sensor face.

Instead of waiting for a yield issue or a complete line down situation, the operator will receive warnings that areas of the machine require attention during normal maintenance.

Calculating the cost of sensor configurations for the downtime related to sensor damage and malfunctions is the key to determining whether switching to smart sensors is right for you. Still unsure if smart sensors are worth the investment?
