This Mixer is Ideal for Viscous Mixing and Dispersion

The PowerMix (photo) includes two separate agitation systems within one mixer. A planetary blade revolves in combination with a separate high-speed dispersion blade. Both revolve on their own axis as well as on a common axis, and the speed of each can be varied independently of the other. This combination allows a user to fine tune the mixer to meet his specific process needs and the shear rates that are required to optimize his process. The PowerMix is used for high-viscosity vacuum mixing and dispersion as well as the dispersion, of minor liquid or powder ingredients into powder mixes. The PowerMix is available in many sizes from a ½-gal laboratory unit, through a 750-gal production model. The unit shown was designed for vacuum operation, included a special light in the vacuum hood, special charging ports, a wall scraper, elevated base and a flush-type discharge valve. — Charles Ross and Son Company, Hauppauge, N.Y.

Manage Hydrogen Hazards in Plant Environments

Hydrogen is a combustible gas that is difficult to detect and easily ignitable on contact with open flames, electrical sparks or static discharge. This fast, ultrasonic gas-leak detector (photo) quickly detects the ultrasonic noise generated by the escaping gas at a distance from the leak source. It detects the gas at leak initiation regardless of ventilation rate, gas dilution or the direction of the leak, and without the gas having to make physical contact with a sensor element. This makes it an ideal choice for detection in vessels and pipes in open and ventilated areas. The detector, which is based on robust microphone technology, has a detection radius for hydrogen up to 8 m at a leak rate of 0.01 kg/s. The detectors are SIL suitability rated and hold relevant C-UL and ATEX certifications. — General Monitors, Lake Forest, Calif.

When the Heat is on, this Device Keeps Pressure Gauges Cool

Extreme process temperatures reduce the accuracy, reliability, durability and lifespan of a pressure gauge. The Sta-Kool cooling element (photo) was designed specifically with high-temperature processing environments in mind. Under laboratory test conditions, the 316L stainless steel Sta-Kool cooling element was able to reduce 400°F liquid process temperatures to 100°F at the active portion of the Bourdon tube. The Sta-Kool has a maximum operating temperature of 750°F at 3,500 psi operating pressure, and a maximum operating pressure of 5,000 psi at 100°F. It can be either threaded or welded to any pressure gauge with ½-in. NPT male connection made from a compatible material. It can also be attached in between a pressure gauge and diaphragm seal for the most comprehensive process measurement-protection possible, protecting the instrument from both pulsation and temperature extremes. — Ametek US Gauge, Largo, Fla.

Online Machine Diagnosis Via W-LAN

Sometimes it is complicated to access machines and equipment that has to be monitored using measuring instruments due to long distances for cables. Use of a wireless-based solution is considerably more efficient and offers greater potential savings. The C300_Wireless system (photo) is installed in a compact switching cabinet with a transmission module. Installation of the monitoring system is simply the mounting of the sensor, installing a switch-gear unit and laying the spur cable. If a failure occurs in the data link, the measured values are stored locally until connection to a control unit has been restored. The heart of the system — online machine diagnostics — is still based on established methods of measuring and evaluating structure-bourne noise signals and intelligently linking them to process data. — DMT GmbH & Co. KG, Essen, Germany
