They can be programmed with a hand-programmer unit, a PC with USB connection, or wirelessly via Bluetooth. The Bluetooth option allows for programming in hard-to-reach places. Versions can measure maximum lengths between 25 mm and 3.25 m. The series offers high-resolution position sensing with up to &plusmn;0.02% full-scale linearity and &plusmn;0.005% FSO&nbsp;repeatability.</p></div> <div class="og_rss_groups"></div><p><a href="http://hydraulicspneumatics.com/controls-instrumentation/position-sensors-eye-extreme-temperatures" target="_blank">read more</a></p> http://hydraulicspneumatics.com/controls-instrumentation/position-sensors-eye-extreme-temperatures#comments Products Controls & Instrumentation Mon, 15 Jun 2015 19:04:00 +0000 33071 at http://hydraulicspneumatics.com Toughened-Up Hitch Control Also Drops in Price http://hydraulicspneumatics.com/controls-instrumentation/toughened-hitch-control-also-drops-price <div class="field-deck"> When introducing an electrohydraulic hitch control to the Indian market, engineers had not accounted for the hostile conditions typically found on Indian farms.

But Robert Burton certainly was. He authored countless books and technical paper covering closed-loop control of electrohydraulic systems. He also contributed to <strong><em>Hydraulics &amp; Pneumatics</em></strong>. And even though his works wer published about 20 years ago, he insight into the behavior of loads, hydraulic flow and pressure, and electronic control are just as relevant today.</p></div> <div class="og_rss_groups"><ul class="links"><li class="og_links first last"><a href="/blog/hitch-post">The Hitch Post</a></li> </ul></div><p><a href="http://hydraulicspneumatics.com/blog/how-calculate-loop-gain-electrohydraulic-servo-systems" target="_blank">read more</a></p> http://hydraulicspneumatics.com/blog/how-calculate-loop-gain-electrohydraulic-servo-systems#comments Controls & Instrumentation The Hitch Post Fri, 29 May 2015 13:31:00 +0000 32721 at http://hydraulicspneumatics.com Has the Next Generation Arrived? http://hydraulicspneumatics.com/controls-instrumentation/has-next-generation-arrived <div class="node-body article-body">Aside from a big jump from analog to digital control, electronics in fluid power has gone through evolutionary changes.
