The unit is CSA–approved for hazardous areas, Class 1 Div 1 Explosion proof Groups A, B, C, D, as well as mining applications, Class 2 Div 1 Groups E, F, G. Standard models are configured with 316L, 17-4 PH, or Inconel 718 materials. With a maximum operating pressure range up to 20,000 PSI (1,378 bar), the AST46SW will maintain high performance with zero signal drift due to an extremely thick and robust sensing diaphragm. Microprocessor technology produces excellent performance over a wide temperature range; advanced electronics, additionally, result in a compact overall size (one inch diameter and less than five inch overall length).
