Gefran - Pressure Sensor | K3 NAK - Sodium Potassium - mV/V Output Get latest price

The K3 Series are pressure sensors  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; strain sensing technology is bonded foil strain gage.

A near incompressible sodium-potassium (i.e. NaK) mixture is used for pressure transmission.

NaK is FDA recognized safe (GRAS) substance.

Application:

• As for FDA approval,  K series is suitable for Mercury free , food and medical application
• Processing  special polymers, technopolymers (538°C /1000°F)

• Pressure ranges from: 0-35 to 0-1000 bar / 0-500 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. NaK is defined as a safe substance (GRAS)
