Industrial Pressure Transducer Provides High Performance

The AccuSense model ASM is an ultra high-performance pressure transducer, designed to provide exceptional accuracy, stability and overpressure protection within demanding test environments. The patented device 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. This expanded protection capability makes the Model ASM the highest performing pressure transducer of its kind on the market. The unique design of the ASM combines Setra Systems’ patented, field-proven, capacitance sensing technology with the very latest in electronic circuitry design, including integral DSP. The pressure transducers are also temperature compensated, with a total error band of less than ±0.25% full scale, minimizing 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. Sensing elements are packaged in a fully laser-welded stainless steel housing, measuring just 1.3 in. in diameter.
