Gefran's HMX series includes pressure sensors with HART communication protocol for use in high temperature environments with the presence of explosive atmospheres.
The main feature of this product line is the ability to read media temperature up to 400°C.
The principle of construction is based on the hydraulic transmission of pressure.
The fluid-filled system ensures temperature stability.
The physical measure is converted into electrical measure through strain gauge technology.
Pressure ranges: 0-17 to 0-2000 bar / 0-250 to 0-30000 psi
Strain measurement principle with a Wheatstone bridge
