Industrial Pressure Transducer

Setra Systems Inc., a leading global designer and manufacturer of pressure measurement instrumentation for industrial, test and measurement, HVAC/R, semiconductor, energy, environmental, medical, pharmaceutical, and meteorological requirements, has introduced the new AccuSense™ Model ASM, an ultra high-performance Industrial Pressure Transducer, designed to provide exceptional accuracy, stability and overpressure protection within demanding test environments. The patented Model ASM ensures excellent linearity and stability, with full-scale end point accuracy of ±0.05%, or ±0.1% of reading. Units are available in ranges from -14.7 PSI to 1000 PSI, with choices of gauge or absolute pressures and 0 to 5 V DC, 0 to 10 V DC, or 4-20 mA outputs, as well as various pressure and electrical connector types, to suit exact user requirements. Overpressure protection of up to 2X proof pressure is standard, with the optional inclusion of a patented high overpressure protection up to 10X proof pressure. The pressure transducers are also temperature compensated, with a total error band (TEB) of less than ±0.25% full scale, minimising thermal errors, and making outputs virtually unaffected by wide environmental temperature shifts. A hydrophobic porous plug at the top of the unit also protects its recessed air vent from environmental contaminants. The transducers also offer high immunity to RFI from wireless devices, for optimal signal output clarity and accuracy. The sensing elements are packaged in a fully laser-welded stainless steel housing, measuring just 1.3 inches (33 mm) in diameter. This compact size allows for easy installation within space constrained environments, allowing the Model ASM to be used as a drop-in replacement upgrade for legacy sensors of the same footprint, particularly where improved measurement capacity, thermal compensation, tighter total error band and higher accuracy are absolute requirements.
