Type V2 Fused Silicon
Pressure Transducer/
Transmitter
• True 1% interc hangeability from
unit to unit – laser trimmed
technology
• Fused silicon for superior linearity
and repeatable performance
• Extremely high pr oof and
pressure tolerance
• Rever se polarity protected
• Wide operating range of
–40
°
to +250
°
F
• EMI/RFI protected – IEC 801-3
• Natural gas vehicle systems
appro vals a vailable; compliant to
NGV 3.1
earity and repeatability perfor-
mance, high proof-and-burst pres-
sure tolerance, and wide operating
temperature capability.
There are no epoxies or organic
materials, such as O-rings, to
contribute to signal instability or
drift. This robust unit is virtually un-
affected by shock, vibration, mount-
ing position, or pressure pulsation.
The wide operating temperature
range, all-stainless steel wetted ma-
terials, high overpressure protection,
and highly reliable Ashcroft electron-
ics make the V Series transducer a
solid choice for many applications.
The V2 transducer meets needs
for a variety of demanding OEM
applications such as compressor,
off-road vehicles and construction
equipment, HVAC/refrigeration,
The new Ashcroft® V2 premier
pressure transducer utilizes fused
silicon strain gage technology. This
unique technology is based on a
principle that results in superior lin-
