The M7 Performance Level 'c' Series are pressure sensors for use in high temperature applications where the process temperatures may reach 400°C (°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 liquid (mercury) is used for pressure transmission.
