NAK Filled Melt Pressure Sensor – Output 4…20mA – SIL2
NAK Sodium Potassium – Output 4…20mA – SIL2
Pressure ranges from: 0-17 to 0-1000 bar / 0-250 to 0-15000 psi
Accuracy: < ±0.25% FS (H); < ±0.5% FS (M)
Hydraulic transmission system for pressure signal guarantees stability at working temperature (NaK) Liquid conforming to RoHS Directive.
The KE Series are for use in high temperature applications where the process temperatures may reach 538°C (1000°F) such as high temperature engineered polymers. The K Series utilizes standard melt pressure principles and construction, but uses a near incompressible NAK (Sodium Potassium) for pressure transmission. The thick film extensimetric technology of KE series provides to transform the physical quantity “pressure” into an electrical signal, in this case 4 to 20 mA. 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.
