Gefran NAK Filled Melt Pressure Sensor – Voltage Output

Overview:

The KN 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 K Series strain sensing technology is bonded foil strain gage

Description:

• Pressure ranges from: 0-35 ato 0-1000 bar / 0-500 to 0-150000 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. NaK is defined as a safe substance (GRAS).
• Quantity of NaK contained per model: KN0 series (30mm3) (0.00183 in³) , KN1, KN2, KN3 (40mm³) (0.00244 in³)
