Melt Pressure Transmitters
ME Series
The ME series are pressure transmitters 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 trasmission 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: ME0 (30mm3 ); ME1, ME2, ME3 (40mm3 )
• 1/2-20UNF, M18x1.5 standard threads; other types available on request
• Autozero function on board / external option
