These transducers offer superior performance in a small 0.75" diameter package. The micromachined silicon sensor has been proven to deliver premium accuracy, elite temperature performance, and long term stability. The silicon sensor is protected by a stainless steel diaphragm which transfers pressure to the sensor by a thin film of silicon oil. The PX409 is ruggedized with a minimum of 4x overpressure protection and secondary containment rated to an even higher pressure. Custom specifications for accuracy, temperature performance, units, fittings, and ranges are available. These models are ideal for industrial, automation, test, automotive, and aerospace applications. The 316SS construction and high accuracy make the PX409 suitable for many oil and gas product applications. It is excellent for calibration, and test applications in the oil industry.
