APPLICATONS
The G3 pressure transducer combines
performance with value to meet the
demanding needs of the original equipment manufacturer in applications
ound in:
f
• Performance Racing
• Railroad/Transportation
• Compressor Control
• HVAC and Refrigeration
• Agricultural Implements
• Process Automation and Control
• Hydraulic & Pneumatic Sensing
• Pump Monitoring
FEATURES
• 1.5% Total Error Band Accuracy
• Broad Temperature Capability
• All-welded 316L SS Wetted Parts
• High EMI/RFI rating
• Ranges vacuum through 300 psi
• Up to IP 67 Ingress rating
• Diagnostic rails
The Ashcroft®Type G3†pressure transducer
has been specifically designed with the high
volume OEM in mind.
The Ashcroft
®
Type G3 pressure transducer
combines a high stability isolated piezoresistive
sensor with our proven ASIC technology to provide a highly accurate and repeatable transducer for both gauge and absolute pressure ranges.
Calibration via digital compensation results in
an extremely accurate instrument over a wide
temperature range. The G3 design is well suited
for demanding, high cycle applications.
The circuitry is held within an internal cage
and housed in an enclosure of reinforced Nylon.
All specifica tions are subject to change witho ut notice.
All sales subject to standard terms a nd conditions.
