Developed by Minco, the sensors can be set to measure gauge or absolute pressures in environments with pressures ranging from 15 to 6000 psi. They produce a 4- to 20-mA analog output and require a supply between 12 and 30 VDC. Accuracy is 0.15% or 0.50% for P8211, while long-term stability for the sensors is 0.15% URL/year.</p></div> <div class="og_rss_groups"></div><p><a href="" target="_blank">read more</a></p> Products Sensors Thu, 26 Feb 2015 19:32:00 +0000 46851 at Guide Simplifies EMI/RFI Shielding Product Selection <div class="node-body article-body"><p>To help its customers find products with characteristics that best match their EMI/RFI shielding applications, Tech-Etch now offers a comparative <em>Shielding Product Guide</em>.

The holders are rugged in vibrational and high shock environments, and batteries may be inserted into the holders using pick-and-place machinery or vacuums. Holders are polarized and have dual-spring, gold-plated phosphor bronze contacts in a glass-filled LCP UL 94V-0 base. They come in bulk (Part #1058) or on tape and reel (Part #1058TR). The battery holder is ISO-9001:2008-certified as well as RoHS- and REACH-compliant.</p></div> <div class="og_rss_groups"></div><p><a href="" target="_blank">read more</a></p> Products Batteries/Power Supplies Thu, 26 Feb 2015 17:14:00 +0000 46831 at For an Energy Source, Look to the Sea <div class="node-body article-body">Global companies and a number of countries are harnessing tides and waves for a new, renewable energy source.</div> <div class="og_rss_groups"></div><p><a href="" target="_blank">read more</a></p> Technologies Energy Thu, 26 Feb 2015 15:18:00 +0000 46811 at <p>All of these systems were designed to operate as an array of turbines.
