Gefran NAK Filled Melt Pressure Sensor – Voltage Output. Sil2

Overview:

The K7 Series are for use in high temperature applications where the process temperatures may reach 538°C (1000°F) such as high temperature engineered polymers. This series utilizes standard melt pressure principles and construction, but uses a near incompressible (NAK Sodium Potassium) for pressure transmission. The phisical quantity is transformed in a electrical measure by means the thick film strain-gauge technology. The SIL2 certified version makes the product suitable for use in the Functional Safety applications, particularly in the process plants for the production of polymers, where it is an essential requirement.
