Performance Level 'c' - 4...20mA output
The ME Performance Level ‘c’ series of Gefran are
Pressure transmitters for use in high temperature environment.
The main characteristic of this series is the capability of
Measuring temperature of the media up to 752 F (400°C) such as high temperature engineered polymers.

The constructive principle is based on the hydraulic transmission
Of the pressure.
The fluid-filled system assures the temperature stability.
The physical measure is transformed in an electrical measure
by means of the strain-gauge technology.

• Pressure ranges from:0-250 to 0-30000 psi  / 0-17 to 0-2000 bar
• 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.
• Auto-zero function on board / external option
• Standard diaphragm is 15-5 PH stainless steel with GTP+ coating
• 17-7 PH corrugated diaphragm with GTP+ coating for ranges below 1500 psi -100 bar
   GTP+ (advanced protection) Coating with high resistance against corrosion, abrasion
   and high temperature

All signal variations in the absence of pressure can be eliminated by using the Auto-zero function.
This function is activated by closing a magnetic contact located on the transmitter housing.
The procedure is permitted only with pressure at zero
