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.
