Chemical Processing-August 2008

equipment & services Graphical Tools Enhance Process Models PlantTriage’s new visual modeling tools reportedly result in better dynamic process models. Better models give better all-around analysis resulting in optimal PID tuning, accurate simulated response to upsets and process noise, and better robustness analysis. The new drag-and-drop modeling puts the engineer in control of the free to vibrate they are driven to their resonant frequency by piezo ceramic elements. As the level of the material to be sensed rises, the material blocks the movement of the fork. The electronics in the unit sense this change and produce an output that can be used for indication or control. Hawk Measurement (888) 429-5538 www.hawkmeasure.com the pneumatic A15EXP-series also consists of two separate models for dry or wet pick-up. NilFisk CFM (800) 645-3475 www.stop-the-dust.com Brush Gear Motor Offers Quiet Operation in Liquid Measurement Applications The ultra-quiet Peristaltic Pump Gear Motor (PPGM) series is designed to power a wide range of peristaltic positive displace- model fit. Using any bump test data, drag the model curve to match the actual response curve. Instantly, PlantTriage finds a dynamic process model that ref lects the visually designed response. ExperTune (262) 369 7711 www.planttriage.com Explosion-Proof Vacuums Add Safety in Wet or Dry Environments This line of explosion-proof vacuums includes both electric and intrinsically-safe pneumatic models. The 118 EXP series is available in two electric models. The 118EXP is for pick-up of dry materials, while the 118 EXPW is equipped for picking up liquids and other wet hazardous materials. They are made entirely of type 304 stainless steel and equipped with conductive accessories to eliminate percussion arcing and static charge. For use in environments where electricity is undesirable or unavailable, August 2008 chemicAlprocessing.com Level Switch Suits Many Materials The level sensing arrangement used in the Gladiator Vibration Switch Series can handle a wide range of liquids and solids, including slurries and pelletized materials. The sensing element includes two prongs or vanes. When the prongs on the fork are ment pumps. Built to withstand the highly cyclical requirements of peristaltic pumps, it develops significant torque at a relatively low operating rate, ensuring long service life and silent operation. Specific pump requirements are translated into torque, speed and current to provide the exact motor response needed for the pump to provide the required f low rate and pressure for the application. The pump gear motor is available in 16and 30-W models and features a gearbox torque of 0.5 Nm nominal and 24V operating voltage.
