KN

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
