DatasheetDynisco LDA415 Pressure Sensor for Washdown Applications
The Dynisco LDA415 Series is designed for food and medical extrusion applications where washdown capability is required. The sensor uses a special high-temperature NaK fill and an Inconel diaphragm, allowing accurate pressure measurement in processes with temperatures up to 538 °C.
The all-welded stainless steel construction provides high reliability, repeatability and suitability for demanding cleaning environments. For easy connection and disconnection, the transducer is available with a 1/2-14 NPT conduit fitting or a 6-pin hermetically sealed Bendix-style connector.
