The M3 series of Gefran, are pressure transducers for using in High temperature environment. The main characteristic of this series is the capability to read temperature of the media up to 400°C. The constructive principle is based on the hydraulic transmission of the pressure. The fluid-filled system assures the temperature stability. The phisical measure is transformed in a electrical measure by means the strain-gauge technology.

Pressure ranges from: 0-35 to 0-2000 bar / 0-500 to 0-30000 psi	Accuracy: <±0.25% FSO (H); <±0.5% FSO (M)
Fluid-filled system for temperature stability	Mercury filling volume: M30 (30mm), M31-M32-M33 (40mm )
1/2-20UNF, M18x1.5 standard threads; other types available on request	Standard diaphragm is 15-5 PH stainless steel with GTP coating
17-7 PH corrugated diaphragm with GTP coating for ranges below 100bar-1500psi
