IIoT-enabled pressure sensor
Pneumatic mini slides Festo festo.us
Aventics www.aventics.com/us/ The Aventics PE5 pressure sensor from Emerson measures systems losses and will alert when the leakage rate exceeds a predetermined value. This enables excessive leaks to be diagnosed early and addressed before they become a significant issue. The sensor has two digital or one digital and one analog outputs. An IO-Link connection makes it simple to connect to an Industrial Internet of Things (IIoT) network. The sensor can be used on new installations or easily added to an existing machine. When the machine is switched off, the PE5 sensor measures pressure loss over time. If the pressure drops faster than desired, a local alert is set, and a signal can be sent via the analog or digital outputs. The local alert consists of a change in display color from green to red. To trigger a maintenance task or to automatically generate a work order, the analog and digital signals can be sent to a PLC or other network. The analog output can be switched between a current or voltage signal and the user has full control over the set points. The IO-Link connection offers additional set up and diagnostic options. The local display also shows how much faster the pressure has dropped than expected.
The DGST pneumatic mini slide is designed for for precision handling, press fitting, pick and place, and electronic and light assembly applications. The DGST slide and yoke plates are machined from a single piece of aluminum, which ensures low torsion and accurate alignment. Backlash free piston rod/yoke connection contributes to the slide’s precision and extended service life. Maintenancefree twin piston drives and high-force capacity recirculating ball bearing guides provide the DGST with twice the power of other slides — from 7.6 to 132.6 lb-ft (34 to 590 N) at 6 bar. Cushioning and proximity sensors do not extend beyond the slide’s footprint, which contributes to the new line’s compactness. Three cushioning options are available. Two slides can be piggybacked in minutes simply by bolting the units together — adaptor plates are not needed. Locating port connections, end-position sensing, and precision end-position adjustment together on one side also contributes to ease of installation. Payloads for the seven different sizes of DGST range from 1.5 to 37.5 lb (0.7 to 17 kg) and stroke length ranges from 0.4 to 8-in. (10 to 200 mm).
Thermoplastic for extreme conditions in oil and gas applications Greene Tweed gtweed.com Arlon 3000 XT thermoplastic for extreme conditions in oil and gas applications delivers improved performance over other available materials; in dynamic mechanical analysis, it demonstrated a glass transition temperature 35° F higher than PEEK and provided superior mechanical property retention from 350° to 600° F. In extrusion testing, Arlon 3000 XT outperformed both virgin and filled grades of PEEK and PEKEKK. Arlon 3000 XT provides improved volume resistivity 30 times that of PEEK at 400° F (204°C) and dielectric strength, measured at 730 V/mil using a 40-mil-thick sample in an ASTM D149 testing. Also, Arlon 3000 XT has 1.5 to 6 times higher mechanical properties compared to PEEK in tensile, compressive, flexural, and shear tests at a test range of 392° to 500° F (200° to 260°C), which provides the support typically provided by a metal element.
