The W7 Performance Level 'c' Series are pressure sensors for use in high temperature applications where the process temperatures may reach 315°C (600°F) such as high temperature engineered polymers.

The W Series utilizes standard melt pressure principles and construction; strain sensing technology is bonded foil strain gauge.

A near incompressible mixture (diathermic oil) is used for pressure transmission.
