Level switch suits tank monitoring, interface control

The NuTec LS2000 level switch is said to provide highly reliable level monitoring and interface control in demanding applications that require precise measurement, long life, low maintenance and cost-of-ownership. The switch is designed for two-wire, 4-20 mA loop power that allows it to serve as a drop-in replacement for other two-wire mechanical float and paddle switches without any wiring modifications during plant retrofit projects, which simplifies installation and reduces cost. The switch also is available for 115/230 Vac or 24 Vdc input power and a 6 A relay output. It features an advanced no-moving-parts thermal mass flow sensor constructed with either 304/305 stainless steel or with 316L all welded stainless steel wetted surfaces for rugged environments. With no moving parts to break, maintenance is claimed to be virtually unnecessary after installation.

Filtering centrifuge filters down to less than 5 microns

The Laboratory/Pilot Plant Filtering Centrifuge is reportedly ideal for replicating the solid/liquid separation performance of larger vertical or horizontal filtering centrifuges. The solids holding capacity ranges from 0.09 (2.5 liters) to 0.26 cubic feet (7.4 liters). Various filtering cloths are available down to less than 5 microns. All contact surfaces are 316 stainless steel on stainless steel base with casters; electrical classification is Class I Division 1. A variable frequency drive (VFD) with digital RPM readout and speed control are on-board in a NEMA-7&9 cabinet. The VFD allows basket speeds of up to 3,600 rpm which can generate separation forces of up to 2,600 G’s.

Pressure transducers deliver in harsh environments

The high-accuracy PX41 Series heavy-duty pressure transducers are rugged, low cost output units for industrial applications and have a FM approved Intrinsically Safe rating standard. Ten-feet (three meters) of four conductor shielded cable is standard. Constructed completely in stainless steel, they reportedly suit the harshest environments. A twist-lock connector is available with the wide selection of amplified and current output models in the PX41 series. The PX41 Series is available in gage, sealed gage, absolute pressure, and a special MSHA approved model is available.

Asset management software optimizes maintenance processes

The iSense software suite is a tool for maintenance, documentation and management of pH and Dissolved Oxygen (DO) sensors. With the software, sensors used in the process are said to be highly accurate, more reliable and become significantly more cost-efficient to maintain. Based on proprietary Intelligent Sensor Management (ISM) technology, the software offers measurement loops for field operation that allow users of process analytical equipment to run their processes using intelligent sensors that are able to provide sensor-specific, real-time status information.

Gas detection system functions in range of climates

The SafEye Xenon 800 Gas Detection System detects a wide range of hydrocarbons over an open path of up to 120 meters. Resistant to false alarms and poisoning, it said to operate well in an extremely wide range of climates. A unique combination of triple optics and dual-spectrum sensor allows the system to maintain operational integrity in up to 90% signal obscuration.

Gas pressure regulators provide accuracy, bubble-tight shut-off

This line of gas pressure regulators is designed with advanced features that  are said to provide superior accuracy and long–term reliable operation. The regulators feature accuracies of ±1% of full scale, as well as compact design, low noise and wide rangeability. The regulators are available in body sizes of 1-in. to 10-in. They boast true top-entry design, which provides for ease of maintenance in all models and sizes, and bubble tight shut-off, for environmental responsibility.  The large rangeability designed into these regulators provides for quieter operation and lower pressure drop through the regulator.

Supervision software gathers data after configuring a single control loop

The wizard builder creates connection wizards for communication between process controllers (DCSs and PLCs) and PC-based software. PlantTriage performance supervision software uses thiswizard technology. To analyze an entire plant, you must first connect to hundreds of data sources in the plant control system. After configuring a single control loop, the wizard builder uses its intelligence about specific control systems to automatically poll the control system for the data it needs. The wizard builder is said to reduce configuration time by up to 90% and practically eliminates address configuration errors.
