The WN series of Gefran, 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 315°C. The constructive principle is based on the hydraulic tra-
smission 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	Strain gage Wheatstone bridge
Accuracy : <±0.25% FSO (H); <±0.5% FSO (M)	Internally generated 80% calibration signal (R-Cal)
Fluid-filled system for temperature stability	Fully interchangeable with all existing brands
Standard diaphragm is 15-5 PH stainless steel with Armoloy coating	17-7 PH corrugated diaphragm with TiN coating (Titanium Nitride) for ranges below 100 bar-1500 psi
Oil filling meets FDA requirements CFR 178.3620 and CFR 172.878	Oil filling volume: WN0 (30mm ); WN1, WN2, WN3 (40mm )
Grade of protection: IP65 (6-pin connector version)	1/2-20 UNF, M18x1.5 standard threads; other types available on request
