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="http://machinedesign.com/sensors/stainless-steel-pressure-sensors-handle-6000-psi" target="_blank">read more</a></p> http://machinedesign.com/sensors/stainless-steel-pressure-sensors-handle-6000-psi#comments Products Sensors Thu, 26 Feb 2015 19:32:00 +0000 46851 at http://machinedesign.com Guide Simplifies EMI/RFI Shielding Product Selection http://machinedesign.com/products/guide-simplifies-emirfi-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>.
