GEFRAN OIL FILLED MELT PRESSURE TRANSMITTERS WN SERIES
• Pressure ranges from:
0-35 to 0-1000 bar / 0-500 to 0-15000 psi
• Accuracy: < ±0.25% FSO (H); < ±0.5% FSO (M)
• Fluid-filled system for temperature stability
• Oil filling meets FDA requirements CFR 178.3620 and
CFR 172.878
• Oil filling volume:
WN0 (30mm3); WN1, WN2, WN3 (40mm3)
• 1/2-20UNF, M18x1.5 standard threads; other types available
on request
• Other diaphragms available on request
• Autozero function on board / external option
• Drift Autocompensation function (SP version)
• 17-7 PH corrugated diaphragm with GTP coating
GTP (advanced protection)
Coating with high resistance against corrosion, abrasion
and high temperature
AUTOZERO FUNCTION
All signal variations in the absence of pressure can be eliminated
by using the Autozero function.
This function is activated by closing a magnetic contact
located on the transmitter housing.
The procedure is permitted only with pressure at zero.
AUTOCOMPENSATES INFLUENCE
OF MELT TEMPERATURE
Thanks to internal self-compensation, the WSP series
transmitter cancels the effect of pressure signal variation
caused by variation of Melt temperature.
This reduces at the minimum the read error caused by
heating of the filling fluid (typical of all sensors built with
“filled” technology).
