Diversity helps to limit effects of unpredictable events. ##### Diversity in factory automation Typically in factory automation a control unit collects data of sensors, analyzes these data and, according to it’s programmed instruction, triggers actuators to a defined operation. In most cases a single-channel structure consisting of sensor, logic and output perfectly fulfills the application requirements. Yet in some cases two-channel structures are preferred to increase the reliability of the control concept.   ##### Clamping control at machine tool spindles [![](https://blog.innovatingautomation.asia/hs-fs/hubfs/Rich%20Text%20Pasting/unknown-1594780378062.jpg?width=520&height=146&name=unknown-1594780378062.jpg)](https://i2.wp.com/www.innovating-automation.blog/wp-content/uploads/2019/08/spindle-position-control.jpg?ssl=1) To monitor clamping positions of tools in machine tool spindles several options are possible: Sensors with binary output (e.g. [PNP normally open](https://www.innovating-automation.blog/an-easy-way-to-remember-pnp-and-npn-sensor-wiring/)) or sensors with continuous output (e.g. 0..10V or [IO-Link](https://www.innovating-automation.blog/back-to-the-basics-what-is-the-value-of-io-link/)) may be installed. The clamping process in many spindles is controlled with hydraulic actuators.This means the clamping force can be controlled by using pressure sensors which control the applied hydraulic pressure in the clamping cylinder.  The combined usage of both position and pressure sensors controls the clamping status in a better manner rather than just using one sensor principle. Typically there are 3 clamping situations: 1) unclasped 2) clamped without object 3) clamped with object. In tooling spindles mostly the clamped position is achieved by using springs which force the mechanics to hold and clamp the object when no pressure is applied. A pneumatic or hydraulic actuator allows to unclasp the object by providing force to overcome the spring load. Without hydraulic or pneumatic pressure therefore the clamped position should be detected by the position sensor. When enough pressure is being built up, after a short delay the unclasped position should be achieved. Otherwise something must be wrong…. ##### The advantage of diversity By using two different sensor principles (in this case pressure sensing and position sensing) the risk of so called common cause failures is reduced. The probability of concurrent effects of environmental impact on the different sensors is diminished, This increases the detection rate of failures. The machine control can immediately react if the signals of pressure and position sensors do not match, which simplifies monitoring of the clamping process. Summary:  Diversity makes life easier in industry.   **For further information:** [Tool Clamping](https://www.balluff.com/en/de/industries-and-solutions/applications/metalworking/monitoring-tool-clamping/) [Overview of pressure sensors](https://www.balluff.com/en/de/productfinder/#/bestseller/ca/F90006?table_page=1&table_size=50) Topics: [IO\_Link](https://blog.innovatingautomation.asia/tag/io_link), [Condition Monitoring](https://blog.innovatingautomation.asia/tag/condition-monitoring), [Mold-ID](https://blog.innovatingautomation.asia/tag/mold-id), [Predictive Maintenance](https://blog.innovatingautomation.asia/tag/predictive-maintenance) - [Tweet](https://twitter.com/share) TAGS [PredictiveMaintenance](https://blog.innovatingautomation.asia/tag/PredictiveMaintenance) [ConditionMonitoring](https://blog.innovatingautomation.asia/tag/ConditionMonitoring) [RFID](https://blog.innovatingautomation.asia/tag/rfid) [MachineVision](https://blog.innovatingautomation.asia/tag/machinevision) [SmartCamera](https://blog.innovatingautomation.asia/tag/smartcamera) [IO\_Link](https://blog.innovatingautomation.asia/tag/io_link) [intralogistics](https://blog.innovatingautomation.asia/tag/intralogistics) [Automobile](https://blog.innovatingautomation.asia/tag/automobile) [IIoT](https://blog.innovatingautomation.asia/tag/iiot) [high temperature](https://blog.innovatingautomation.asia/tag/hightemperature) [industry\_4.0](https://blog.innovatingautomation.asia/tag/industry_4.0?hsLang=en) ### Subscribe for more [![New Call-to-action](https://no-cache.hubspot.com/cta/default/7010809/43c13478-58e0-42a3-af82-b5e6159d8af8.png)](https://cta-redirect.hubspot.com/cta/redirect/7010809/43c13478-58e0-42a3-af82-b5e6159d8af8) Document © Balluff Automation - [![](https://app01.balluff.com/image-fit/30-30/fileadmin/user_upload/germany/icons/fb-icon.png)](http://www.facebook.com/Balluffworldwide) - [![](https://app01.balluff.com/image-fit/30-30/fileadmin/user_upload/germany/icons/linkedin-icon.png)](http://www.linkedin.com/company/5340578?trk=prof-exp-company-name) - [![](https://app01.balluff.com/image-fit/30-30/fileadmin/user_upload/germany/icons/tweet-icon.png)](http://twitter.com/balluff?lang=de) - [![](https://app01.balluff.com/image-fit/30-30/fileadmin/user_upload/germany/icons/youtube-icon.png)](http://www.youtube.com/user/BalluffSensors) [General Terms and Conditions](https://www.balluff.com.cn/en/cn/documents/general-sales-terms-and-conditions/) [Contact](https://www.balluff.com.cn/en/cn/contacts/contact/) [Imprint](https://www.balluff.com.cn/en/cn/documents/imprint/) [Privacy Statement](https://www.balluff.com.cn/en/cn/documents/privacy-statement/)
