0 to 15000 psi; 0 to 20000 psi; 0 to 350 bar; 0 to 400 bar;
0 to 700 bar; 0 to 1000 bar; 0 to 1350 bar
• High accuracy ±0.1 %FSS BFSL (Model 435);
standard accuracy ±0.2 %FSS BFSL (Models 434/435/437)
• Standard aperture (Models 434/435) and wide aperture
(Model 437) pressure ports support media blends with
high viscosities
• Inconel® X-750 or optional NACE-compliant Inconel® 718
wetted parts
• Multiple electrical connectors supported
• Pressure connections: WECO® 1502, 2002, 2202
• High accuracy 1-wire or 2-wire shunt calibration option allows
ability to validate the offset signal in the field, ensuring the
sensor is actively plugged into the system
• Protective cage option
• RFI/EMI protected
• Intrinsically safe: CFMUS/ATEX/IEC Ex certification
• CE approved


Potential Applications

Acidizing, choke manifold, fracturing and cementing,
measurement while drilling (MWD), mud pumps/mud logging,
new well development and extraction, oil and gas drilling,
service and cement trucks, standpipe, stimulation, well head



• High or standard accuracy allow ability to obtain tighter
system requirements and lower error bands than comparable
competitive models
• Shunt calibration option enhances configurability and
flexibility; 1-wire shunt calibration is achievable with a single
barrier application, helping to minimize installation costs
• IEC Ex approval allows for use in hazardous areas, in AsiaPacific
and EMEA, and by the U.S. Coast Guard
• Protective cage option
• Welded construction 



Models 434/435/437 Wing Union/Hammer Union Pressure
Sensors are designed for demanding oil and gas applications as
well as stimulation and circulation systems. They are constructed
as an all-welded, stainless steel assembly with the sensor
diaphragm and wing union fitting machined as one part, which
provides hermetic integrity and minimizes media leakage versus
multi-piece parts. The isolated pressure sensing diaphragm
minimizes zero-shift during hammer up and eliminates longterm
signal drift in the field. The Weco® 1502, 2002, and 2202
Wing Union-compatible fittings are machined of Inconel® X-750,
or optional NACE-compliant Inconel® 718, allowing for use
with abrasive and corrosive media. The Honeywell proprietary
stainless steel electrical connection provides enhanced
secondary pressure containment. Special assembly processes
provide enhanced shock and vibration for reliable performance
in the field.
