The PX835 explosion proof / flame proof pressure transmitter is ideal for a broad spectrum of pressure sensing requirements, requiring hazardous location approvals for explosion proof, flame proof or intrinsically safe. The PX835 is designed with an all welded stainless steel case and manufactured to provide the user with accurate, reliable, and stable output data. This is accomplished through the use of state of the art sensor technology combined with digital calibration to provide extremely linear and precise performance over the entire specified pressure and temperature range.
