The Kobold KPA Series Pressure Sensor combine several unique features to provide an instrument that is tough, accurate, and economical. Both the fitting and the sensing diaphragm are precision machined out of a single piece of 17-4 PH stainless steel. Because there are no welds or seals, the KPA offers an exceptionally high cycle life. The semiconductor strain gauges are kiln fused to the diaphragm for a highly stable molecular bond that resists strain caused by applications with high pressure pulsations. It has a 4-20 mA, 2-wire transmitter and a 1/4" NPT fitting. Other options are available in OEM quantities. The KPA provides significant levels of RFI, EMI, and ESD protection which makes it an ideal choice for industrial applications.
