Sensor de pressão Wing union/Hammer union
Principais características


• Quick delivery service
• Inconel® X-750 wetted parts for additional durability with
abrasive or corrosive media
• ±0.2 % accuracy BFSL
• Rugged, robust design
• RFI/EMI protected
• Optional on-board temperature sensor
• Optional one wire (with IS approval) or two-wire (without
IS approval) shunt calibration allows users the ability to
validate the offset signal in the field, ensuring the sensor is
actively plugged into the system
• Intrinsically safe
• CE approved; CSA/ATEX certification

Potential Applications

• Acidizing
• Choke manifold
• Fracturing and cementing
• Mud pumps / mud logging
• New well development and extraction
• Oil and gas drilling
• Service and cement trucks
• Standpipe
• Stimulation
• Well head measurement 



The Model 424 Wing Union Pressure Sensors are rugged
sensors designed for use with 2002 and 2202 wing unions in
demanding land-based and off-shore applications.
The isolated pressure sensing diaphragm minimizes zero shift
during hammer-up and eliminates long-term signal drift in the
field. The sensor diaphragm and wing union fitting are machined
as one part. Model 424 is constructed as an all-welded assembly
using a deep penetration, proprietary, electron beam welding
process which also ensures hermetic integrity for all field conditions.
These sensors incorporate special assembly processes
to vibration and shock proof the components to ensure performance
is maintained during the rigors of fracturing and cementing
applications. The Model 424 Wing Union is machined
of Inconel® X-750, providing service with highly abrasive and
corrosive media
